How would I append the text to the file using the code below?
I notice there is an option to append in the FileStream fs declaration line; but this is not where I want to put it.

CODE:

```
        Console.WriteLine(s2 + "g");
        FileStream fs = new FileStream(s2 + ".txt", FileMode.OpenOrCreate);
        StreamWriter sw = new StreamWriter(fs);
        Console.SetOut(sw);
        Console.WriteLine(s2);
        sw.Close();

```
