[DataContract] 的命名空间 [英] Namespace for [DataContract]

问题描述

我找不到用于 [DataContract] 和 [DataMember] 元素的命名空间.根据我的发现，添加以下内容似乎就足够了，但在我的情况下还不够.

I can't find the namespace to use for [DataContract] and [DataMember] elements. According to what I've found, it seems that adding the following should be enough, but in my case it is not.

using System;
using System.Runtime.Serialization;

这是我的代码片段:

using System;
using System.Runtime.Serialization;

namespace MyNamespace {

    [DataContract]
    public class Tuple<T1, T2> {
            // A custom implementation of a Tuple
            //...
            //...
        }
}

我得到的错误:

找不到类型或命名空间名称DataContract"(您是否缺少 using 指令或程序集引用?)

The type or namespace name 'DataContract' could not be found (are you missing a using directive or an assembly reference?)

我是否使用了正确的命名空间?

Am I not using the right namespaces?

推荐答案

DataContractAttribute 类位于 System.Runtime.Serialization 命名空间中.

DataContractAttribute Class is in the System.Runtime.Serialization namespace.

您应该添加对 System.Runtime.Serialization.dll 的引用.尽管默认情况下不引用该程序集.要添加对项目的引用，您必须在解决方案资源管理器中转到引用 -> 添加引用并手动添加程序集引用.

You should add a reference to System.Runtime.Serialization.dll. That assembly isn't referenced by default though. To add the reference to your project you have to go to References -> Add Reference in the Solution Explorer and add an assembly reference manually.
