C#: marshalling a struct that contains arrays

Question

I am doing some C# interop work. I have the following struct:

#pragma pack(push,1)
typedef struct
{
    unsigned __int64 Handle;
    LinkType_t Type;
    Lin         


        

Answer 1

whenever I initialize the struct the Name, DeviceInfo, and Reserved fields are all set to null

This is correct, and your definition looks OK to me (BTW, you don't need [MarshalAs] on the primitive fields, the default behaviour is to do what you specified there). Because your array fields are null, the marshaler won't do anything about them when marshaling your struct to unmanaged memory, but it's going to create the strings and arrays when unmarshaling.
