Question

我有要转换为Byte []数组的员工对象列表...

我使用以下代码进行转换：

 private byte[] ObjectToByteArray(List<Employee> obj)
        {
            if (obj == null)
                return null;
            var bf = new BinaryFormatter();
            var ms = new MemoryStream();
            bf.Serialize(ms, obj);
            return ms.ToArray();
        }

但它给了我以下错误..

我是否需要使用SerializableAttribute装饰我的班级成员？

Answer 1

至少，您需要确保将Employee（以及所有组成成员）标记为可序列化。

感谢您发布堆栈跟踪，但如果这不能解决您的问题，那么异常消息也会有所帮助！

将List <employee>转换为Byte [] array </employee>
