The IntPtr type is designed to be an integer whose size is the same as a pointer. That is, an instance of this type is expected to be 32 bits in a 32-bit process and 64 bits in a 64-bit process.The IntPtr type can be used by languages that support pointers and as a common ...
MSVC targeting 32-bit x86 gives__int64a minimum alignment of 4, butits default struct-packing rules align types within structs tomin(8, sizeof(T)) relative to the start of the struct.(For non-aggregate types only). That's not a direct quote, that's my paraphrase of theMSVC docs link...
