我有这样的JSON，我想读在Windows Phone上。我一直在玩 DataContractJsonSerializer 和Json.NET但实际上并没有多少运气，尤其是阅读每一个'入门'：

I have this JSON which I am trying to read on Windows Phone. I've been playing with DataContractJsonSerializer and Json.NET but had not much luck, especially reading each 'entry':

{"lastUpdated":"16:12","filterOut":[],"people":
[{"ID":"x","Name":"x","Age":"x"},{"ID":"x","Name":"x","Age":"x"},{"ID":"x","Name":"x","Age":"x"}],
 "serviceDisruptions":
  {
    "infoMessages":
    ["blah blah text"],
    "importantMessages":
    [],
    "criticalMessages":
    []
  }
}

我所关心的是，在人们部分中的条目。基本上，我需要阅读并遍历（包括ID，姓名，年龄值）的条目，并将其添加到集合或类。 （我填充列表框之后。）

All I care about is the entries in the people section. Basically I need to read and iterate through the entries (containing the ID, Name, Age values) and add them to a Collection or class. (I am populating a listbox afterwards.)

任何指针AP preciated。

Any pointers appreciated.

推荐答案

我可以用下面的code反序列化的JSON字符串。这是在.NET 4控制台应用程序进行测试，并希望将WP 7正常工作。

I was able to deserialize your JSON string using the following code. This was tested in a .NET 4 console application, and hopefully will work in WP 7 as well.

DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(PersonCollection));

string json =  "{\"lastUpdated\":\"16:12\",\"filterOut\":[],\"people\": [{\"ID\":\"a\",\"Name\":\"b\",\"Age\":\"c\"},{\"ID\":\"d\",\"Name\":\"e\",\"Age\":\"f\"},{\"ID\":\"x\",\"Name\":\"y\",\"Age\":\"z\"}], \"serviceDisruptions\": { \"infoMessages\": [\"blah blah text\"], \"importantMessages\": [], \"criticalMessages\": [] } }";

using (var stream = new MemoryStream(Encoding.Unicode.GetBytes(json)))
{
    var people = (PersonCollection)serializer.ReadObject(stream);

    foreach(var person in people.People)
    {
        Console.WriteLine("ID: {0}, Name: {1}, Age: {2}", person.ID, person.Name, person.Age);
    }
}   

使用下列数据类：

Using the following data classes:

[DataContract]
public class PersonCollection
{
    [DataMember(Name = "people")]
    public IEnumerable<Person> People { get; set; }
}

[DataContract]
public class Person
{
    [DataMember]
    public string ID { get; set; }

    [DataMember]
    public string Name { get; set; }

    [DataMember]
    public string Age { get; set; }
}
