If you've ever had to write any interop code to use an unmanaged library in your C# application, you know how tricky it can be to get the data types correct. I often find myself scouring the internet looking for the correct conversions, so I thought I would document everything I have learned so far. This is by no means a comprehensive list of all C++ data types, just the ones I find myself frequently writing interop code for.

C++ Type	C# Type	Size
BOOL	bool	1 byte
BYTE	byte	1 byte
CHAR	byte	1 byte
DECIMAL	Decimal	16 bytes
DOUBLE	double	8 bytes
DWORD	uint, UInt32	4 bytes
FLOAT	float, single	4 bytes
INT, signed int	int, Int32	4 bytes
INT16, signed short int	short, Int16	2 bytes
INT32, signed int	int, Int32	4 bytes
INT64	long, Int64	8 bytes
LONG	int, Int32	4 bytes
LONG32, signed int	int, Int32	4 bytes
LONG64	long, Int64	8 bytes
LONGLONG	long, Int64	8 bytes
SHORT, signed short int	short, Int16	2 bytes
UCHAR, unsigned char	byte	1 byte
UINT, unsigned int	uint, UInt32	4 bytes
UINT16, WORD	ushort, UInt16	2 bytes
UINT32, unsigned int	uint, UInt32	4 bytes
UINT64	ulong, UInt64	8 bytes
ULONG, unsigned long	uint, UInt32	4 bytes
ULONG32	uint, UInt32	4 bytes
ULONG64	ulong, UInt64	8 bytes
ULONGLONG	ulong, UInt64	8 bytes
WORD	ushort	2 bytes
void*, pointers	IntPtr	x86=4 bytes, x64=8 bytes

If I am missing something, or you would like me to include something else, please let me know in the comments below. Thanks!
