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

Try this.

string path = @"E:\AppServ\Example.txt";
if (!File.Exists(path))
{
    using (var txtFile = File.AppendText(path))
    {
        txtFile.WriteLine("The very first line!");
    }
}
else if (File.Exists(path))
{     
    using (var txtFile = File.AppendText(path))
    {
        txtFile.WriteLine("The next line!");
    }
}
