问题描述
有什么方法可以告诉 WCF 在返回时序列化整个类?我真的必须将 DataMember 添加到每个属性中吗?
Are there any ways to tell WCF to serialize the whole class when it returns? Do I literally have to add DataMember to every property?
推荐答案
自 .NET 3.5 SP1 起，您无需再执行此操作.
Since .NET 3.5 SP1, you don't have to do this anymore.
如果您没有任何 [DataContract] 和 [DataMember] 属性，DataContractSerializer 类的行为将与旧的 XmlSerializer 类似:它将序列化所有公共读取/编写类中列出的属性.
If you don't have any [DataContract] and [DataMember] attributes, the DataContractSerializer class will behave like the old XmlSerializer: it will serialize all public read/write properties that are listed in the class.
虽然在这个过程中你确实失去了一些东西:
You do lose a few things in the process though:
由于您没有
[DataMember]属性，您不能再定义字段的顺序 - 它们将按照出现的顺序进行序列化
since you don't have
[DataMember]attributes, you cannot define an order of the fields anymore - they'll be serialized in the order of appearance
您不能省略公共属性(因为这需要在所有其他属性/字段上使用 [DataMember])
you cannot omit a public property (since that would require [DataMember] on all other properties/fields)
您不能将属性定义为 Required(这将再次出现在 [DataMember] 属性上)
you cannot define a property to be Required (that would be on the [DataMember] attribute again)
你的类现在需要有一个公共的、无参数的构造函数(数据契约通常不需要)
your class now needs to have a public, parameter-less constructor (usually not needed for data contracts)
