I am planning to create a window app for comparing text, web content, code similar to textcompare.io

[bond009]

Hello Team,

I want to create a Windows app to compare text using C# for my college project. I would like to have a compare view similar to https://textcompare.io 

I have attached the image. Is there any library in C# that supports this kind of comparison? Or can I use any different development stack to develop the app in Windows that support compare component,

 

Thank you

there are already several existing apps that can do this including Notepad++ and Visual Studio Code, is there are reason you're needing/wanting to create your own solution?

don't have to use an online reviewer.

The lions share of such an app would be in the comparison library, and that's the part you're wanting to find pre-written code for?

Sounds suspiciously like homework or an assignment, but even with the benefit of the doubt on that - what would your app bring to the table that existing, well developed and supported apps don't already have?

The first google result for "C# text comparison library" yields this: https://github.com/mmanela/diffplex

This stack overflow post has some information that is a little old but could be a solution for you: https://stackoverflow.com/questions/138331/any-decent-text-diff-merge-engine-for-net

Lastly, if you want to write this yourself, check out Microsoft's documentation on the topic: https://learn.microsoft.com/en-us/dotnet/csharp/how-to/compare-strings

Monaco Code Editor (the same one used in VSCode) can already do this out of the box with only a few lines of code.

If this is for your college project (AKA Homework)... It would seem to me that the purpose is to write your own algorithm to parse, tokenize, compare the strings, then format the data for output.

This is easily done in both windows forms and asp.net web forms in C#, but you have to write the code yourself...

I wanted to develop a tool where I could have more control over the data and apply the union concept. i.e., If I have two lists, I can compare them; I apply the union concept and find out which data is different in what and copy only that data from either of the inputs. 

@satukoro,

I am looking at your answer, and it will help me to start developing my own text comparison. 

@PmRd After checking your reply, I understood https://textcompare.io using the monaco editor; thank you.

If I get stuck, I will ask again.. thank you..
