如何在 ASP.NET 中从 json 反序列化基本类型（System.Runtime.Serialization.Json）

我有一个小问题。当我将 DataContractJsonSerializer 与复杂类型（自己的类型）一起使用时，它工作正常。但我必须从字符串反序列化 TimeStamp 或 DateTime 。所以我无法用 DataContract、DataMember 属性标记这些类型。

我写了一些代码

string jsonedTS = "PT2M15S";

DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(TimeSpan));
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonedTS));
try {
    result.Takes = (TimeSpan) jsonSerializer.ReadObject(ms);
} catch {
 ;
}

并且捕获了这个异常

{“反序列化 System.TimeSpan 类型的对象时出错。遇到意外字符 'P'。”} System.Exception {System.Runtime.Serialization.SerializationException}

我的问题是我怎样才能反序列化

I have a little problem.
When I'm using DataContractJsonSerializer with complex types(own types) it works fine. But I have to deserialize TimeStamp or DateTime from a string. So I cant mark these types with DataContract, DataMember attributes.

I wrote some code

string jsonedTS = "PT2M15S";

DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(TimeSpan));
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonedTS));
try {
    result.Takes = (TimeSpan) jsonSerializer.ReadObject(ms);
} catch {
 ;
}

And I catch this Exception

{"There was an error deserializing the object of type System.TimeSpan. Encountered unexpected character 'P'."} System.Exception {System.Runtime.Serialization.SerializationException}

And My Question IS
How Can I deserialize
