StructLayout and Size problem

[Guest]

Hi,

can anyone figure it out, why this code works fine on Full Framwork, but not
correctly on Compact framework. In particular, I see that size of the struct
is igonred in CF (always 8 according to
System.Runtime.InteropServices.Marshal.SizeOf)

[StructLayout(LayoutKind.Sequential, Size=64)]
private struct TestStruct
{
public int data1;
public int data2;
}

Can anyone help me,
Bostjan

Marshalling is limited in .NETCF compared to the desktop, your structure
should be defined as the full size with members in sequential order, for
complex structures you can pass a byte array and then pull out the
individual members using BitConverter etc.
Here are a couple of articles on P/Invoke/Marshalling:-
