2.Intptr、byte[]互相转换

//IntPtr转byte[]<br><br>IntPtr y;//初始化 略 byte[] ys = new byte[yLength]; Marshal.Copy(y, ys, 0, yLength);<br><br><br><br>//byte[]转换为Intptr         public static Intptr BytesToIntptr(byte[] bytes)         {             int size = bytes.Length;             IntPtr buffer = Marshal.AllocHGlobal(size);             try             {                 Marshal.Copy(bytes, 0, buffer, size);                 return buffer;             }             finally             {                 Marshal.FreeHGlobal(buffer);             }         }

 

至于struct和Intptr转换，完全可以参考上面的函数
