How to add a line to an existing txt with C#

Question

I would like to an a new line to a txt file. I've tried this with StreamWriter but it seems to clear the txt then add the line i want and nothing else. I was just wondering is there away to do where i keep the data inside the txt its adding a line too?

Thanks, Josh

You need to use `new StreamWriter("c:\\file.txt", true);` to append to a file rather than overwriting it, see the SO question in the comment by @J3soon for further details. — Alex, Dec 31 '15 at 17:59

Simple:

File.AppendAllText("file.txt", "Some Text to Append");

If you want to use StreamWriter then you just need to specify true for the append argument.

new StreamWriter("file.txt", true);
