C#byte[]structintptr等的相互转换

Posted 2022-01-21 【君莫笑】

一、struct byte[]互相转换

      //struct转换为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[]转换为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[]互相转换

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


       //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);
