[C#] How do i insert a string to top of Text File?

[$phinX]

I need to add a line of text to the top of a file in my C# app.

I can create files ok, i can append to the end of files ok, but how do i insert a string at, say, line 1?

Please help!!

I'm not sure of the most efficient way, but this way works:

string filename = "c:\\test.txt";

string entireFile = "";

if (File.Exists(filename))

{

StreamReader reader = new StreamReader(filename);

entireFile = reader.ReadToEnd();

reader.Close();

}

StreamWriter writer = new StreamWriter(filename);

writer.WriteLine("This line is pre-pended");

writer.Write(entireFile);

writer.Close();

Instead of opening it using FileMode.Append, use FileMode.Open and I think it'll move stuff back but I'm not totally sure

no, it wont work

AFAIK The only way you can do it is to open the file, copy everything in there, add your text, then paste the stuff from before.

so it would be somethin like what kjordan posted
