Media Player Project

 Hello there,
I have a problem pulling a .MP3 file from a domainUpDown control to play when I click the play butten. Im sure Im just doing somethin stupid, lol.
 domainUpDown is named "lbMedia"openFileDialog is named "ofdSelectMedia"play button is named "button5"  
 my C# code is written as follows:
private void button5_Click(object sender, EventArgs e)
{
        this.open("lbMedia(" + ofdSelectMedia.FileName + ")");
} 
error->does not contain a def for 'open' (i'm assuming I havent used 'open' correctly?)

error->are you missing an using directive or an assembly reference?
Please help, I realize that if it where a .WAV file it would probably be a lot easier, and I am obviously missing some references.
