My question would be: why? This question is not as trivial as it may seem.

Basically you can't, without some fairly advanced use of Reflection to recursively parse your type and get the sizes of each of it's constituent parts - which may well have their own contained classes, which may... you get the idea.

And it'll be sloooow.

There is apparently another way. Have a look at this: http://blog.softwx.net/2013/01/benchmarking-c-struct-and-object-sizes.html[^] it's C#, not VB, but it does do the job - apparently, I haven't tried it. I have serious doubts about it's accuracy, given that the code tries up to twelve times to get a consistent result on the same object...if the GC won't tell you the same thing twice in a row, what hope have you got?

Part of the idea of .NET is that for most applications, you aren't supposed to think about the size of your objects - just get on an use them.
