C#byte[]、struct、intptr等的相互轉換

一、struct byte[]互相轉換

      //struct轉換為byte[]
       public static byte[] StructToBytes(object structObj)
       {
           int size = Marshal.SizeOf(structObj);
           IntPtr buffer = Marshal.AllocHGlobal(size);
           try
           {
               Marshal.StructureToPtr(structObj, buffer, false);
               byte[] bytes = new byte[size];
               Marshal.Copy(buffer, bytes, 0, size);
               return bytes;
           }
           finally
           {
               Marshal.FreeHGlobal(buffer);
           }
       }
 
       //byte[]轉換為struct
       public static object BytesToStruct(byte[] bytes, Type type)
       {
           int size = Marshal.SizeOf(type);
           IntPtr buffer = Marshal.AllocHGlobal(size);
           try
           {
               Marshal.Copy(bytes, 0, buffer, size);
               return Marshal.PtrToStructure(buffer, type);
           }
           finally
           {
               Marshal.FreeHGlobal(buffer);
           }
       }

二、Intptr、byte[]互相轉換

        //IntPtr轉byte[]
        IntPtr y=new IntPtr();
        byte[] ys = new byte[yLength];
        Marshal.Copy(y, ys, 0, yLength);


       //byte[]轉換為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);
            }
        }
