Going to C# from heavy Python experience


Question

Hey there! I'm a noob and I need help.

 

 

I've been given certain liberties on my companies next GUI adventures and after enough research I've decided I'm going with Visual C#. The ease of Visual Studio with the friendliness of C# seems like an excellent combination. The only problem is.... I don't really know C#. I get the basic Syntax, it's pretty straight forward as I have quite a bit of experience with PHP (and less so with C) but I know I need to drastically improve. Partial Classes, for example, scare me. Although so does this odd thing known as compiling and strong typing.

 

 

Answer Guide:

Keep in mind I'm a visual person and have never been very good with books. Sure I can read and comprehend but I have a much easier time with watching by example and taking apart other peoples code on github or something. This doesn't mean I don't want books, just that they are second fiddle.

 

Question:

As a heavy Python3/Qt4/MySQL programmer where is the best place to start learning C#?

 

Are there any projects you know of written in C# that would be easy for me to dissect?

 

Do you have any experience with both Python and C# and know a thing or two about important differences / "gotchas"?

 

 

Thanks a ton!

If you've done a lot of any object-oriented language then the syntax of C# should not be a huge issue. Stackoverflow has an awesome C# community, if you ask a question there it usually gets answered in 5 minutes. I'm an expert on C# and .NET so I can probably answer most of your questions as well.

 

I think the bigger change from Python is getting to know .NET, the underlying platform: how code is compiled into assemblies, how assemblies can reference each other, how garbage collection works in regards to reference and value types, all the basic types in the root System namespace (Object, String, Type, etc.) that sort of thing. .NET is a wonderful development environment with excellent documentation, comprehensive, high quality libraries, and this is reflected in many independent open-source projects that build on the platform. Personally, I'm totally spoiled and wouldn't use anything else these days. C# was consistently designed as a "pit of success": usually the most obvious thing to do is the best thing to do (unlike in some other *cough languages).

 

If you're going to do GUI programming, WPF can be a pretty tough pill to swallow. Try to focus on one thing at a time.

 

Coming from Python you're likely used to exploratory programming inside the REPL. Visual Studio doesn't provide a C# REPL, but LINQPad is a great alternative.

 

I'm not convinced of the value of learning by reading other code; perhaps you can understand it but it'll be hard for you to figure out why it was coded this way. A really good book for experienced programmers is C# in a Nutshell. For an in-depth treatment of the .NET platform (once you have some experience with it), read CLR via C#.

I'm glad you're an expert. For the most part I'm fairly self-sufficient but I may ask direct C# questions from time to time (so long as I haven't found something on S.O. yet).

 

I agree on C#, it looks like a wonderful language so far and I'm a bit disappointed I overlooked it the first time around. I believe there were some issues with Linux compatibility at the time that immediately removed it from my "check it out" list. Now that's no longer of concern.

 

I've been working out the Windows Form Application but haven't touched WPF; I'll stay away for now. WFA however is very straight forward and simple.

 

I don't really touch the REPL much these days but I agree it was a big help in the beginning, I'll take a look a LINQPad. Thanks.

 

I read other peoples code not to understand the syntax but the reasoning. I don't generally get into that until I have a firm grasp of the language, but the one thing I don't want to happen is code Python in C#. There is a C# way of doing things and in general other peoples code are a good indicator of those methods. I've never been formally taught so I have to learn formalities and methodologies the hard way, unfortunately.

 

Thanks for the help. I'll check those books out.

It's usually referred to as WinForms. ;)

I'm having a really good time with it so far. I wish I got into this much sooner.

 

Update:

I enjoy the type system. I didn't think I'd like strongly typed languages (I didn't like it in C) but I actually find it gives a certain peace of mind after a while. I'm not a fan of using the 'new' keyword to instantiate a new object reference (and arrays), but, I guess I'll just have to deal (I'm not a big fan of the explicit 'self' parameter in Python methods either, so...win some, lose some).

 

I've got the basics down, including Structs, Enums, Classes, Arrays and anything easier than those. Having a heck of a time. I haven't touched generics or threads, but I don't think they'll be too difficult. Time will tell.

To be precise, C# is statically typed whereas Python is dynamically typed, i.e., every identifier has a fixed type which can be figured out just by looking at the code, whereas in Python types are assigned and can change at run time. The terms "weak" and "strong" typing don't have well-defined meanings.

 

Glad to know you're having fun with it!

I always recommend csharp-station to people looking to learn C#. The tutorials are well written, short enough not to feel overwhelming, but long enough to give you all of the basics that you need. And as Andre suggested, Stack Overflow is an invaluable tool. Definitely consult that site when you run into a problem.

Right now I'm reading "C# Yellow Book" by Rob Miles. I like the way he breaks things down with some light humor thrown in. After which I will read "C# in a nutshell" which I've ordered online and just waiting to arrive. If by the end of that 1000 page "nutshell" I need a bit more I'll take a look at your suggestion. I'm also reading "Code The Hidden Language" and "The C Programming Language" in the meantime as suggested by Joel Spolsky from Stack Exchange. 

 

I just can't take on anymore books right now lol. I will however look into it.

Sorry, still not very good at terminology. I'm a decent to pretty good programmer, but as I was all self taught the terminology sometimes escapes me; if I even know it at all.

Small note about that. The types in C# are aliases for the actual types in .NET. In that fashion, int is an alias to Int32, long to Int64, and so on. You might find it sometimes to be more appropriate to use the .NET types, particularly if you share code with non-C# .NET developers (VB.NET, F#...). They would know exactly what the types are, instead of going through C# documentation to read on what "long" means.

 

It is something so simple, and it really depends on your usage, but it is something to give a thought or two about. Personally, I've started to use the .NET types, thus I'm getting a clear distinction between types and other C# keywords (they're not with the same colour). Not that it matters that much, but still, I like my cake this way! :laugh:

I personally go by what the language specification recommends:

 

  Quote
Each of the predefined types is shorthand for a system-provided type. For example, the keyword int refers to the struct System.Int32. As a matter of style, use of the keyword is favored over use of the complete system type name. http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-334.pdf (page 18)

I have to take one of your sides, and Andre is Green. If Ruby Rod taught me anything it was that it must be green. Thanks guys though, I'm glad I know it's an alias.

It seems like you are well on your way with C# and the .NET framework. My story was different... I started with C# etc... but switched to Python because of its no brainer syntax. However, my days with C# is far from over and I still sometimes go back to it when I am building a web based enterprise application. .NET has some awesome libraries that makes things much faster.

 

Anyhow, I would feel really bad if you found the following tools later than now. I don't want you to spend your wheels and waste too much time because the following tools and resources made my applications look super awesome even though I was still a complete noob ;)... don't tell that to my employers now!

Probably the best video tutorial series I came across for .NET stuff. The basic C# was well enough but the ASP.NET part also made me very comfortable toward the web.

Ah, thanks for that. I may at some point actually use devexpress, very pretty.

 

As for the video series, thanks but I have little interest in using ASP.NET.

Not sure if someone has already posted this or you have already looked at but check out http://code.msdn.microsoft.com/

 

You can pretty much get any code sample by filtering it from the left.

 

For 3rd party WinForms controls, I can vouch for DevExpress controls. Been using them since 2003. Great controls and excellent support and cuts down a lot of development time.

    • They are always there, available third week every month, not fully public tho
    • Lol, sounds like you're not up to date with reality and are just repeating what the salesman told ya. Here's a little insight for you: Electric Cars Are Way Less Reliable Than ICE Cars, Says Consumer Reports. Alas, you're entitled to your wrong opinion.
    • misleading its one word to describe what M$ have done, windows 10 perform better on older hardware and even on new hardware sometimes, windows 11 its a mess and no one want to use it for many good reasons, until they listen its customers read the feedback hub comments and maybe backoff its forced requiremens, they are having a vista and 8 moment.
    • Media Player Classic - Home Cinema 2.5.0 by Razvan Serea Media Player Classic - Home Cinema (MPC-HC) is a free and open-source video and audio player for Windows. MPC-HC is based on the original Guliverkli project (which is no longer maintained) and contains many additional features and bug fixes. As the continuation of the original Media Player Classic, MPC-HC isn’t flashy but it works with nearly any media format. MPC-HC uses DXVA technology to pass decoding operations to your modern video card, enhancing your viewing experience. And MPC-HC supports both physical and software DVDs with menus, chapter navigation, and subtitles. Overview of features A lot of people seem to be unaware of some of the awesome features that have been added to MPC-HC in the past years. Here is a list of useful options and features that everyone should know about: Dark interface Menu > View > Dark Theme When using dark theme it is also possible to change the height of the seekbar and size of the toolbar buttons. Options > Advanced Video preview on the seekbar Options > Tweaks > Show preview on seek bar Adjust playback speed Menu > Play > Playback rate The buttons in the player that control playback rate take a 2x step by default. This can be customized to smaller values (like 10%): Options > Playback > Speed step Adjusting playback speed works best with the internal audio renderer. This also has automatic pitch correction. Options > Playback > Output > Audio Renderer MPC-HC can remember playback position, so you can resume from that point later Options > Player > History You can quickly seek through a video with Ctrl + Mouse Scrollwheel. You can jump to next/previous file in a folder by pressing PageUp/PageDown. You can perform automatic actions at end of file. For example to go to next file or close player. Options > Playback > After Playback (permanent setting) Menu > Play > After Playback (for current file only) A-B repeat - You can loop a segment of a video. Press [ and ] to set start and stop markers. You can rotate/flip/mirror/stretch/zoom the video Menu > View > Pan&Scan This is also easily done with hotkeys (see below). There are lots of keyboard hotkeys and mouse actions to control the player. They can be customized as well. Options > Player > Keys Tip: there is a search box above the table. You can stream videos directly from Youtube and many other video websites You can stream videos directly from Youtube and many other video websites Put yt-dlp.exe or youtube-dl.exe in the MPC-HC installation folder. Then you can open website URLs in the player: Menu > File > Open File/URL You can even download those videos: Menu > File > Save a copy Tip: to be able to download in best quality with yt-dlp/youtube-dl, it is recommended to also put ffmpeg.exe in the MPC-HC folder. Several YDL configuration options are found here: Options > Advanced This includes an option to specify the location of the .exe in case you don't want to put it in MPC-HC folder. Play HDR video This requires using madVR or MPC Video Renderer. After installation these renderers can be selected here: Options > Playback > Output Ability to search for and download subtitles, either automatically or manually (press D): Options > Subtitles > Misc Besides all these (new) features, there have also been many bugfixes and internal improvements in the player in the past years that give better performance and stability. It also has updated internal codecs. Support was added for CUE sheets, WebVTT subtitles, etc. Media Player Classic - Home Cinema 2.5.0 changelog: Updated LAV Filters to version 0.80-1-gb9116 Updated MPC Video Renderer to version 0.9.9.2400 Several small fixes and improvements. Graphics Designers Wanted for New Toolbar Buttons A new toolbar is planned for implementation in the player, featuring optional extra buttons and fully customizable layouts. As a result, existing custom toolbar designs will no longer be supported in the future. New button designs are needed, and contributions from graphics designers are welcome. Those interested in helping create the new toolbar are encouraged to read the dedicated information page.
