sizeof

[Guest]

What is the equivalent of sizeof in VB.NET?
In C# you can write:
nTotalSize += sizeof(int);

what is the equivalent in VB.NET?

Tom Shelton provided this advice:

monitorInfo.cbSize = Marshal.SizeOf(monitorInfo)

monitorInfo.cbSize = Marshal.SizeOf(monitorInfo)

ACK. Notice that this will require an "instance" of the type instead of the
type name.

You're wrong there.
Look carefully at the overloads and you will see that one of them takes a
type 'Object', the other takes a type 'Type'.

Try this:

Imports System.Runtime.InteropServices
Module Module1
Sub Main()
Debug.WriteLine(Marshal.SizeOf(GetType(Int32)))
End Sub
End Module


No objects constructed.

What prompted you to suggest this, are we talking about different versions of
the .NET framework or something? You sounded pretty sure.

I would use DirectCast but hey it works....

Ooops. Scrolled through the overloads in IntelliSense too quickly...

No, you are right, I missed the overload.
