On net 4.0, I get:
Unhandled Exception: System.ArgumentException: The specified structure must be
blittable or have layout information.
Parameter name: structure
at System.Runtime.InteropServices.Marshal.StructureToPtr(Object structure,
IntPtr ptr, Boolean fDeleteOld)
at Program.Main(String[] args)
for this testcase:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
using System;
using System.Runtime.InteropServices;
[StructLayout (LayoutKind.Auto)]
public class SimpleClass {
}
class Program
{
static void Main (string[] args)
{
SimpleClass c = new SimpleClass ();
IntPtr p = Marshal.AllocHGlobal (1024);
Marshal.StructureToPtr (c, p, false);
}
}
