有什么方法可以让 DataContractJsonSerializer 正确序列化字典? [英] Any way to make DataContractJsonSerializer serialize Dictionaries properly?

问题描述

DataContractJsonSerializer 无法正确序列化字典.

The DataContractJsonSerializer is not able to serialize Dictionaries properly.

JavaScriptSerializer 将字典序列化为 {"abc":"xyz","def":42}例如，DataContractJsonSerializer 给 [{"Key":"abc","Value":"xyz"},{"Key":"def","Value":42}] 代替.

Whereas JavaScriptSerializer serializes Dictionaries as {"abc":"xyz","def":42} for example, the DataContractJsonSerializer gives [{"Key":"abc","Value":"xyz"},{"Key":"def","Value":42}] instead.

这确实有问题，我想知道如何在 WCF 服务中正确序列化 Dictionary 对象.我正在寻找一种需要最少努力的解决方案.

This is really problematic and I want to know how can I serialize Dictionary objects correctly in my WCF service. I am looking for a solution that would require least amount of effort.

推荐答案

使用 DataContractJsonSerializerSettings(从 .NET 4.5 开始可用)可以为您做到这一点:

Using DataContractJsonSerializerSettings (available since .NET 4.5) can do this for you:

var serializer = new DataContractJsonSerializer(typeOfObj, new DataContractJsonSerializerSettings()
{
    UseSimpleDictionaryFormat = true 
});
