Hi,
You can use FileStream class to create or open file and use StreamWriter class to write into file.

Here is an example :

using System.IO;

class TestWriteFile
{

public static void Main()
{

FileStream fs = new FileStream("text.txt", FileMode.Create);
StreamWriter w = new StreamWriter(fs);
w.WriteLine("This is a test string");
w.Flush();
w.Close();
fs.Close();
}
}
