process argument contains space in filename

Hi everyone:

I want to play a song by clicking a button. For example if i want to play song using windows media player here is the code....On click of play button

Process myProcess = new Process();

myProcess.StartInfo.FileName ="wmplayer";

myProcess.StartInfo.Arguments = @"C:\bin\pleaseforgiveme.mp3";

myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Normal;

myProcess.Start();

This works fine. The problem i am having right now is if the file name is C:\bin\Please forgive me.mp3 i.e if it has whitespaces in the file (space b/w please forgive me) it does n't play the file. Or if it has underscore(_) in file name like please_forgive_me it does not play file. It throws exception. Could any of you help me in this ?

Thanks and with regards

The problem is that escaping the string with @ actually does not escape the special characters like spaces within the string.

One approach is to explicitly escape special characters within the string with \

For example,

void Button2Click(object sender, System.EventArgs e)
{
      try
      {
       Process myProcess = new Process();
       myProcess.StartInfo.FileName ="wmplayer";
       myProcess.StartInfo.Arguments = "\"d:\\dnload\\music\\01 - I'm A Mover.mp3\"";
       MessageBox.Show(myProcess.StartInfo.Arguments.ToString());
       myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
       myProcess.Start();
      }
      catch(Exception ex)
      {
            MessageBox.Show(ex.Message+ex.StackTrace);
      }
}

This works just fine and plays the song.
