// collection, and retrieves its index if it is found.
CodeExpression testComment = new CodePrimitiveExpression(true);
int itemIndex = -1;
if( collection.Contains( testComment ) )
    itemIndex = collection.IndexOf( testComment );
' Tests for the presence of a CodeExpression in the 
' collection, and retrieves its index if it is found.
Dim testComment = New CodePrimitiveExpression(True)
Dim itemIndex As Integer = -1
If collection.Contains(testComment) Then
    itemIndex = collection.IndexOf(testComment)
