DataContractJsonSerializer

DataContractJsonSerializer

环境:Windows 10 Fall Creators Update上的Visual Studio 2017(1709)

目标:使用DataContractJsonSerializer序列化JSON对象

问题:我无法解决DataContractJsonSerializer。在查看项目引用时,我尝试将System.Runtime.Serializtion(v4.0.30319)添加到我的引用中,但是没有运气。是否需要访问DataContractJsonSerializer的其他参考/程序包。

替代方案:是的,我知道我可以使用NewtonSoft.Json,并且可能会但想要一个结论性的答案,然后再向项目中添加其他依赖项。

研究:我曾尝试过在Google以及SO上寻找SO,但DataContractJsonSerializer仍然受到很高的引用,并且在发生问题的原因上我找不到最不明显的东西。

最佳答案

对Yaakov的感谢,我知道发生了什么。
对于第一次使用DataContractJsonSerializer的用户,请记住在执行该操作后手动将引用添加到System.Runtime.Serialization。
您应该能够解析“使用System.Runtime.Serialization.Json;”。

就我而言,我猜想在添加参考之后,我只是看到VS不满意,因此没有手动构建它。所以我在正确的路上只是没有给它足够的时间:)
