Create a .txt file if doesn't exist, and if it does append a new line

Question

I would like to create a .txt file and write to it, and if the file already exists I just want to append some more lines:

string path = @\"E:\\AppServ\\Examp         


        

Answer 1

 else if (File.Exists(path)) 
{ 
  using (StreamWriter w = File.AppendText(path))
        {
            w.WriteLine("The next line!"); 
            w.Close();
        }
 }
