CodeExpression^ testComment = gcnew 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.
CodeExpression testComment = new CodePrimitiveExpression(true);
int itemIndex = -1;
if( collection.Contains( testComment ) )
    itemIndex = collection.IndexOf( testComment );

' collection, and retrieves its index if it is found.
