Question

环境：Windows 10 Fall Creators更新中的Visual Studio 2017（1709）

目标：使用DataContractJsonSerializer序列化JSON对象

问题：我无法解析DataContractJsonSerializer。看看y项目参考我尝试将System.Runtime.Serializtion（v4.0.30319）添加到我的参考文献但没有运气。是否需要额外的参考/包来访问DataContractJsonSerializer。

替代：是的，我知道我可以使用NewtonSoft.Json，但在向项目添加额外的依赖项之前可能会想要一个确定的答案。

研究：我试图在Google和Google上使用DataContractJsonSerializer仍然被高度引用，但在找不到可能出错的地方时，我找不到至关重要的内容。

Answer 1

对Yaakov来说，我知道发生了什么事。对于那些第一次使用DataContractJsonSerializer的人，请记住在执行此操作后手动添加对 System.Runtime.Serialization 的引用你应该能够解决＆＃34;使用System.Runtime.Serialization.Json;＆＃34;

在我的情况下，我想在添加引用后，我刚看到VS并不高兴，然后没有手动构建它。所以我在正确的轨道上没有给它足够的时间:)）

DataContractJsonSerializer不可用
