C# 在WP7中反序列化JSON

我有这个JSON，我正试图在Windows Phone上阅读它。我一直在玩

DataContractJsonSerializer

和Json.NET，但运气不太好，尤其是阅读每个“条目”：

{"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":
    []
  }
}

我所关心的是人物部分的条目。基本上，我需要读取和迭代条目（包含ID、Name、Age值）并将它们添加到集合或类中。（之后我将填充一个列表框。）

任何指针都值得欣赏。

我能够使用以下代码对JSON字符串进行反序列化。这是在.NET4控制台应用程序中测试的，希望也能在WP7中使用

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);
    }
}   

使用以下数据类：

[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; }
}

[DataContract]
公共类个人集合
{
[DataMember（Name=“people”）]
公共IEnumerable人{get；set；}
}
[数据合同]
公共阶层人士
{
[数据成员]
公共字符串ID{get；set；}
[数据成员]
公共字符串名称{get；set；}
[数据成员]
公共字符串年龄{get；set；}
}

下面的解决方案使用Json.NET。它首先将JSON字符串反序列化为XML，然后使用LINQ to XML迭代所有人员节点，并将它们转换为

Person

类的实例

private class Person
{
    public string ID { get; set; }
    public string Name { get; set; }
    public string Age { get; set; }
}

// deserializes your JSON and creates a list of Person objects from it
private void button1_Click(object sender, RoutedEventArgs e)
{
    // your JSON
    string json =
        "{\"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\":" +
        "[]" +
        "}" +
        "}";

    // deserialize from JSON to XML
    XDocument doc = JsonConvert.DeserializeXNode(json, "root");

    // iterate all people nodes and create Person objects
    IEnumerable<Person> people = from person in doc.Element("root").Elements("people")
                                 select new Person()
                                 {
                                     ID = person.Element("ID").Value,
                                     Name = person.Element("Name").Value,
                                     Age = person.Element("Age").Value
                                 };

    // this is just demonstrating that it worked
    foreach (Person person in people)
        Debug.WriteLine(person.Name);
}

这就是反序列化JSON作为XML文档的样子（对于好奇的人来说）：

16:12

废话

您的示例不是有效的json，请发布真实内容：-）好的，我刚刚更改了文本并将其格式化为单独的行。为什么你说它是无效的？这是完美的谢谢你，我很好地修改了它来填充我的收藏。对我来说，棘手的一点是如何列举它，但PersonCollection似乎很好地解决了这个问题。
