Question

I have written some code for playing a .wav through my application. Now I want to play a mp3 file through.

I have .NET framework 1.1

if you have .NET framework 1.1. only, probably your best approach is to use a P/Invoke wrapper for mciSendCommand

[DllImport("winmm.dll")]
private static extern long mciSendString(
        string strCommand, StringBuilder returnString, 
        int returnBufferLength, IntPtr callback);

void PlayFile(string mp3FileName)
{
    string deviceType = "MPEGVideo";
    string fileName = mp3FileName;
    string alias = "MyMp3File";
    string playCommand = string.Format("open \"{0}\" type {1} alias {2}",
                            fileName, deviceType, alias);
    mciSendString(playCommand, null, 0, IntPtr.Zero);
    playCommand = string.Format("play {0} from 0", alias);
    mciSendString(playCommand, null, 0, IntPtr.Zero);

    // send these when you are finished
    // playCommand = "stop MyMp3File";
    // playCommand = "close MyMp3File";
}
