在WP7中反序列化JSON

我有这个JSON，我试图在Windows Phone上阅读。 我一直在玩DataContractJsonSerializer和Json.NET，但运气不好，特别是阅读每个’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": [] } } 

我所关心的只是人物部分的条目。 基本上我需要读取并遍历条目（包含ID，Name，Age值）并将它们添加到Collection或类中。 （之后我填充了一个列表框。）

任何指针赞赏。

我能够使用以下代码反序列化您的JSON字符串。 这是在.NET 4控制台应用程序中测试的，并且希望也能在WP 7中运行。

 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 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; } }

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 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); } 

不要忘记import：

 using Newtonsoft.Json; using System.Xml.Linq; using System.Diagnostics; 

这就是反序列化的JSON看起来像XML文档（对于那些好奇的人）：

  16:12  x x x   x x x   x x x   blah blah text
