DesignerVerb^ testVerb = gcnew DesignerVerb( "Example designer verb", gcnew EventHandler( this, &Class1::ExampleEvent ) );
int itemIndex = -1;
if ( collection->Contains( testVerb ) )
         itemIndex = collection->IndexOf( testVerb );

// Tests for the presence of a DesignerVerb in the collection, 
// and retrieves its index if it is found.
DesignerVerb testVerb = new DesignerVerb("Example designer verb", new EventHandler(this.ExampleEvent));
int itemIndex = -1;
if( collection.Contains( testVerb ) )
    itemIndex = collection.IndexOf( testVerb );

' Tests for the presence of a DesignerVerb in the collection, 
' and retrieves its index if it is found.
Dim testVerb As New DesignerVerb("Example designer verb", New EventHandler(AddressOf Me.ExampleEvent))
Dim itemIndex As Integer = -1
If collection.Contains(testVerb) Then
    itemIndex = collection.IndexOf(testVerb)
End If
