Re: StreamWriter Truncating Output

Be sure to call Close on your streams.  You can do this automatically as
the object goes out of scope if you use the "using" statement
(recommended):

using(StreamReader sr = new StreamReader(inputfile))
{
  using(StreamWriter sw = new StreamWriter(outputfile))
  {
    string line = "";
    while ((line = sr.ReadLine()) != null)
    {
     sw.Write(line + "\r\n");
    }
  }
}
