Emulate C datatypes in C#

Question

Is there a way to emulate special C datatypes, like uint64 (_int64), anyID (_int16) in C#? I defined the special datatypes in C like this:

typedef unsigned _int16 anyID;
typedef unsigned _int64 uint64;

Its for using the TS3 Plugin API. It has to be C# though, and I just want to use the from TS3 defined C datatypes in C#.

The equivalent of a typedef is using:

using anyID = System.UInt16;
using uint64 = System.UInt64;

The sizes of the different numeric types in C# can be found here: Integral Types Table.

One thing to note: the sizes of the different numeric types are fixed in C#, unlike in C where they are platform-dependent, so it's usually redundant to define aliases for numeric type sizes like int64.

Interesting that while `ushort` is normally equivalent to `System.UInt16`, for the `using` it isn't... – xanatos Mar 03 '17 at 09:45
Yup, that got me at first, too. – Alex Mar 03 '17 at 09:46

unsigned ints are already predefined See MS c# types

in short: ushort is an unsigned 16bit int, and ulong is an unsigned 64bit int..

And how can I declare an alias? So like, when I write uint64 it takes it as ulong? – J.Horr Mar 03 '17 at 09:33
Use a using statement such as using _int16 = ushort; – BugFinder Mar 03 '17 at 09:35
Turns out ushort is an alias anyway, so you can do "using _int16= System.UInt16;" – BugFinder Mar 03 '17 at 09:41

For unsigned integers you have ushort, uint and ulong, which is the equivalent to unsigned int16, unsigned int32 and unsigned int64 respectively.
