如何忽略使用BinaryFormatter序列化的属性?

本文介绍了如何忽略使用BinaryFormatter序列化的属性?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 [Serializable] class DOThis { private string _name; public string Name { get { return _name; } set { _name = value; } } public string Value { get { if (_name == "Hi") return "Hey Hi"; else return "Sorry I dont know you"; } } }

我有上述要使用BinaryFormatter序列化的类.下面是序列化代码，

I have the above class to be serialized using BinaryFormatter. Below is the serialization code,

DOThis obj = new DOThis(); obj.Name = "Ho"; BinaryFormatter bfm = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); bfm.Serialize(ms, obj);

在这里如何忽略序列化和反序列化的值"属性，因为我始终可以使用名称"属性来检索值"属性?

Here how to ignore the property 'Value' from being serialized and also in deserialize, as I can always retrieve 'Value' property using 'Name' property?

推荐答案

您不必对代码进行任何更改:BinaryFormatter仅序列化字段，而不对属性进行序列化，因此不会对Value进行序列化.

You don't have to make any changes to your code: BinaryFormatter only serializes fields, not properties, so it won't serialize Value.

这是结果MemoryStream的十六进制转储，显示仅序列化了"_name"和"Ho":

Here's a hex dump of the resulting MemoryStream which shows that only "_name" and "Ho" are serialized:
