C#的struct和byte[]数组的互相转化

public class StructureHelper
    {
        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);
            }
        }

        //将Byte转换为结构体类型
        public static object ByteToStruct(byte[] bytes, Type type)
        {
            int size = Marshal.SizeOf(type);
            if (size > bytes.Length)
            {
                return null;
            }
            //分配结构体内存空间
            IntPtr structPtr = Marshal.AllocHGlobal(size);
            //将byte数组拷贝到分配好的内存空间
            Marshal.Copy(bytes, 0, structPtr, size);
            //将内存空间转换为目标结构体
            object obj = Marshal.PtrToStructure(structPtr, type);
            //释放内存空间
            Marshal.FreeHGlobal(structPtr);
            return obj;
        }
