C# 用于反序列化Json的DataContractJsonSerializer

我正在尝试反序列化

Json

字符串。我的反序列化工作到

OrderData

。 当我反序列化时，

OrderData

总是

null

并且

SourceData

也不显示。它也没有抛出任何错误。有什么解决这个问题的建议吗

    string jsonString = @" 
        {
            ""RequestId"":514106,
            ""Warning"":[],
            ""CustomerData"": {
                ""Email"":""abc@abc.com"",
                ""FullName"":""OrTguOfE"",
                ""OrderData"":[{
                    ""OrderId"":""123"",
                    ""SourceId"":""0"",
                    ""SourceData"": [{
                        ""SourceDescription"":""This is sourcedesc"",
                        ""ProductName"":""xyzabc""
                    }]
                }]
            }
        }";

我的反序列化代码如下所示：

RecordInfo records= Deserialize<RecordInfo>(jsonString);
private static T Deserialize<T>(string jsonString)
{

    using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(jsonString)))
    {
       var serializer = new DataContractJsonSerializer(typeof(T));
       return (T)serializer.ReadObject(ms);
    }
}

---

代码的问题在于，在JSON中，

CustomerData

对象中的

OrderData

成员的类型是数组，但在类型定义中是对象。同样，JSON中的

SourceData

是一个数组，但在类型定义中是一个对象

如果更改如下所示的类型定义，则应该能够使用

DataContractJsonSerializer

对其进行正确的反序列化
