MemCpy in C#

Here's an example of implementing a fast equivalent of MemCpy in C# using DynamicMethods.

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Drawing.Imaging;
using System.Linq;
using System.Reflection;
using System.Reflection.Emit;
using System.Runtime.InteropServices;
using System.Text;

namespace Test
{
public unsafe class Program
{
 public delegate void MemCpyFunction(void *des, void *src, uint bytes);

 private static readonly MemCpyFunction MemCpy;

 static Program()
 {
     var dynamicMethod = new DynamicMethod
     (
         "MemCpy",
         typeof(void),
         new [] { typeof(void *), typeof(void *), typeof(uint) },
         typeof(Program)
     );

     var ilGenerator = dynamicMethod.GetILGenerator();

     ilGenerator.Emit(OpCodes.Ldarg_0);
     ilGenerator.Emit(OpCodes.Ldarg_1);
     ilGenerator.Emit(OpCodes.Ldarg_2);

     ilGenerator.Emit(OpCodes.Cpblk);
     ilGenerator.Emit(OpCodes.Ret);

     MemCpy = (MemCpyFunction)dynamicMethod
                 .CreateDelegate(typeof(MemCpyFunction));
 }

 static void Main(string[] args)
 {
     var point1 = new Point
                  {
                      X = 10,
                      Y = 20
                  };

     var point2 = new Point();

     MemCpy(&point2, &point1, (uint)sizeof(Point));
 }
}
}
