Passing Arrays between C# and C++

Visual C# General

Tim79

I have a Managed C++ DLL which I'm using to wrap calls to a C Lib by a third party vendor. The input is a Word8 array and it's output is a Word16 array. I believe that the equivelant types are short and sbyte respectivly. I've spent the whole day trying to find out how to pass these arrays between the C# code and the C++ DLL. I'll just throw out that I'm using VS2005.

Thanks in Advance,
Tim

Well first off do you know if your Word8 and Word16 are signed or unsigned
Second you got your bit numbers flipped.
Word8 == sbyte or byte (signed or unsigned)
Word16 == short or ushort (signed or unsigned)

Second, what is the C library's function stub How does this compare to what your using for you P/Invoke stub

Sorry, I noticed I switched them around typing up the problem. Let me take a second shot at this and state the issue clearer.

I need to call C++ .Net DLL from C# sending in a Word8 array and getting back a Word16 array. The original data being sent in is simply a C# byte[] and the output I get back will be converted to a C# byte[] also. I can write whatever signature in C++ that I need to accomplish this. I also can pass the data byte array in any format as long as I can convert the byte array to a Word8 array. The Word8 and Word16 arrays are signed.

example signature
Word16 decode(Word8 inbuffer[]);
