How to create .NET structures in IronPython?

[Hubbl3]

HI I am trying to convert some C# code and have run into an issue when trying to marshal a structure pointer. So as an example here is the C# psuedo code:

[StructLayout(LayoutKind.Sequential)]
public struct EXAMPLE_StTRUCT
{
     public ushort Var1;
     public ushort Var2;
}

IntPtr pStruct;

<do some stuff to get the correct ptr>
Struct = Marshal.PtrToStructure<EXAMPLE_STRUCT>(pStruct);

I have been using Ctypes.Structure in previous projects without having many problems but it appears that Marshall.PtrtoStructure can't get the layout information with those. StructLayout does not appear to be importable directly so I have imported StructLayoutAttribute which seems like the correct thing but I haven't figured out to be able to build the struct still. I have tried applying it as a decorator like:

@StructLayoutAttribute(LayoutKind.Sequential)
class EXAMPLE_STRUCT:
        _fields_ = [('Var1', System.Int32),
                    ('Var1',System.Int32)]

but that throws an error about StructLayoutAttribute not being callable. I have also tried:

class EXAMPLE_STRUCT(StructLayoutAttribute(LayoutKind.Sequential)):
     _fields_ = [('Var1', System.Int32),
                   ('Var1',System.Int32)]

but that fails with an error about the meta class which leads me to believe I need to do something like:

class SECURITY_LOGON_SESSION_DATA:
    __metaclass__ = type
    __clrtype__ = StructLayoutAttribute(LayoutKind.Sequential)
    _fields_ = [('Var1', System.Int32),
                   ('Var1',System.Int32)]

but when I call Marshal.PtrToStructure(pStruct, EXAMPLE_STRUCT) I still get an error about my struct needing to be blittable. Thanks for the help y'all are a great community.
