Is there a way of doing the below in vb.net because the Or command will not work with a string.

If diaOpenFile.FileName.ToLower.Contains(".mp3" Or ".wma") Then

Thanks, James

String filename = diaOpenFile.FileName.ToLower();
Boolean isAudio = filename.EndsWith("mp3") || filename.EndsWith("wma");

if(isAudio) {
    
    // do work
    
}
Or in VB:

Dim filename As String = diaOpenFile.FileName.ToLower();
Dim isAudio As Boolean = filename.EndsWith("mp3") OrElse filename.EndsWith("wma");

If isAudio
    
    ' do work
    
End If

Oh the temptations for stroking my ego!

....but if you feel my (let's face it) insignificant contribution has made a definite improvement to your product feel free.

if( !succeed( try() ) ) { while(true) try(); }
Oooh, let's throw in lambda expressions, just for the hell of it:

bool isAudio = (new string[]{ ".mp3", ".wma" }).All(
  x => diaOpenFile.FileName.ToLower.Contains(x) );

is diaOpenFile a instance of System.Windows.Forms.OpenFileDialog? if yes you could use the Filter property to filter file types from the start:

diaOpenFile..Filter = "Audio files|*.mp3|*.wma|"
