How to write a text file in C#

I need to write a strings into a text file from C#, each string on 开发者_StackOverflowa new line...How can I do this?

You can use File.WriteAllLines:

string[] mystrings = new string[] { "Foo", "Bar", "Baz", "Qux" };

System.IO.File.WriteAllLines("myfile.txt", mystrings);

If you wish to append the text lines to the file, use AppendAllText:

string appendText = "This is extra text" + Environment.NewLine;
File.AppendAllText(path, appendText);

How about StreamWriter class? Read more here...

And do not forget about exception handling e.g missing file permissions etc.

Use the StreamWriter class; take a look at this tutorial. A new line is simply the character \n (Unix) or the characters \r\n (Windows).
