What is the C# equivalent of C++ DWORD?

Question

After searching, I heard that UInt32 was the C# equivalent of C++ DWORD. I tested results by performing the arithmetic

*(DWORD*)(1 + 0x2C) //C++
(UInt32)(1 + 0x2C) //C#

They produce completely different results. Can someone please tell me the correct match for DWORD in C#?

Answer 1

Your example is using the DWORD as a pointer, which is most likely an invalid pointer. I'm assuming you meant DWORD by itself.

DWORD is defined as unsigned long, which ends up being a 32-bit unsigned integer.

uint (System.UInt32) should be a match.

#import <stdio.h>

// I'm on macOS right now, so I'm defining DWORD
// the way that Win32 defines it.
typedef unsigned long DWORD;

int main() {
    DWORD d = (DWORD)(1 + 0x2C);
    int i = (int)d;
    printf("value: %d\n", i);
    return 0;
}

Output: 45

public class Program
{
    public static void Main()
    {
        uint d = (uint)(1 + 0x2C);
        System.Console.WriteLine("Value: {0}", d);
    }
}

Output: 45
