    I recall reading somewhere that not all of the "My" objects available to VB function properly in C#. Since most of the objects provided through the "My" keyword are available to C# through other means, it's probably better in the long run to spend a little more time to write the code for that directly. You didn't say exactly what property you were trying to access when the exception occurred, but from what I can see that's available through the ComputerInfo class you'll probably have to resort to pinvoke to get most of that info.
