Ｃ＃下，struct与字节数组的相互转换

public struct TControlRequest
{
      public int     Code;               // command code
      public int     UserID;             // user id, 0=inner system

      public unsafe fixed char    Param[200];         // parament
};

 

   public struct TControlResponse
   {
      public int     Result;             // result
      public unsafe fixed char Param[200];         // parament of result
   };

 

      //将TControlRequest转换为字节数组

      private byte[] TControlRequestToBytes(TControlRequest request)
      {
         int iSize = Marshal.SizeOf(typeof(TControlRequest));
         IntPtr pCertCont = Marshal.AllocHGlobal(iSize);
         Marshal.StructureToPtr(request, pCertCont, true);

         byte[] myWriteBuffer = new byte[iSize];
         Marshal.Copy(pCertCont, myWriteBuffer, 0, iSize);

         return myWriteBuffer;
      }
