Array.Copy and Buffer.BlockCopy both do the same thing, but BlockCopy is aimed at fast byte-level primitive array copying, whereas Copy is the general-purpose implementation. My question is - under ...

I am copying N bytes from pSrc to pDest. This can be done in a single loop: for (int i = 0; i < N; i++) *pDest++ = *pSrc++ Why is this slower than memcpy or memmove? What tricks do they use to ...

I understand unsafe code is more appropriate to access things like the Windows API and do unsafe type castings than to write more performant code, but I would like to ask you if you have ever noticed ...

How do I marshal this C++ type? The ABS_DATA structure is used to associate an arbitrarily long data block with the length information. The declared length of the Data array is 1, but the actual ...

I have a system where a remote agent sends serialized structures (from an embedded C system) for me to read and store via IP/UDP. In some cases I need to send back the same structure types. I thought ...

I have an unsafe byte* pointing to a native byte array of known length. How can I convert it to byte[]? An unsafe sbyte* pointing to a zero-terminated native string can be converted to a C# string ...

There appears to be multiple ways to do this, but the examples I've tried haven't worked for me. I read somewhere that using unsafe pointers would be the way to go for more complex structures that ...

This is the original declaration: [StructLayout(LayoutKind.Explicit, Size = 16)] public unsafe struct X { [FieldOffset(0)] public ushort a; [FieldOffset(2)] public fixed byte b[14]; }; I would ...

I have a legacy application written in Delphi 2007 which generates byte arrays like this: command_data = packed record direction : word; name : array [0..9] of char; end; ...

I want to use a function written in C in C# application. The function is exported to dll file. C function code: #include <stdio.h> #include <stdlib.h> extern "C" __declspec(...
