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

Use the correct constructor:

else if (File.Exists(path))
{
    using(var tw = new StreamWriter(path, true))
    {
        tw.WriteLine("The next line!");
    }
}
