我现在正在做一个Windows Phone项目，需要向Web服务请求一些json数据。 如果json结构是这样的 [Dictionary1， Dictionary2， Dictionary3 ] 那么，DataContractJsonSerializer工作正常。 但是下一个请求我将得到一个复杂的json数据，它不起作用。喜欢 [ [Dictionary1] [Dictionary2] [Dictionary3] ]
真实数据是：
[
[{"length":5734.042,"duration":1680,"legs":
[
{"length":685,"duration":555.42,"type":"walk","locs":
[
{"coord":{"x":2546445,"y":6675512},"arrTime":"201203290959","depTime":"201203290959","name":null},
{"coord":{"x":2546433.8,"y":6675498.3},"arrTime":"201203291000","depTime":"201203291000","name":"Teekkaripolku"}
]
},
{"length":4158,"duration":420,"type":"5","code":"2506 2","locs":
[
{"coord":{"x":2546168,"y":6674959},"arrTime":"201203291009","depTime":"201203291009","name":"Alvar Aallon puisto","code":"2222235","shortCode":"E2226","stopAddress":"Otaniementie"},

，班级模型是：
[DataContract]
public class RouteList
{
[DataMember]
public List<Route> oneRoute;
}
---
[DataContract]
public class Route
{
[DataMember(Name = "length", IsRequired = true)]
public Double length { get; set; }
[DataMember(Name = "duration", IsRequired = true)]
public Double duration { get; set; }
[DataMember(Name = "legs", IsRequired = true)]
public List<Leg> legs { get; set; }
}
----
[DataContract]
public class Leg
{
[DataMember(Name = "length", IsRequired = true)]
public Double length { get; set; }
[DataMember(Name = "duration", IsRequired = true)]
public Double duration { get; set; }
[DataMember(Name = "type", IsRequired = true)]
public String type { get; set; }
[DataMember(Name = "code", IsRequired = false)]
public String code { get; set; }
[DataMember(Name = "locs", IsRequired = true)]
public List<Loc> locs { get; set; }
[DataMember(Name = "shape", IsRequired = false)]
public String shape { get; set; }
}
-----
[DataContract]
public class Loc
{
[DataMember(Name = "coord", IsRequired = true)]
public String coord { get; set; }
[DataMember(Name = "arrTime", IsRequired = true)]
public String arrTime { get; set; }
[DataMember(Name = "depTime", IsRequired = true)]
public String depTime { get; set; }
[DataMember(Name = "name", IsRequired = true)]
public String name { get; set; }
[DataMember(Name = "code", IsRequired = false)]
public String code { get; set; }
[DataMember(Name = "shortCode", IsRequired = false)]
public String shortCode { get; set; }
[DataMember(Name = "stopAddress", IsRequired = false)]
public String stopAddress { get; set; }
}
和反序列化代码：
System.IO.MemoryStream mStream = new System.IO.MemoryStream(System.Text.Encoding.UTF8.GetBytes(e.Result));
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(List<RouteList>));
result = (List<RouteList>)serializer.ReadObject(mStream);
我尝试过DataContractJsonSerializer和json.NET。但失败了。最可能的问题是嵌套数组，模型：RouteList。有谁知道如何解决它？非常感谢。
答案 0 :(得分：1)
问题可能是因为您的类创建，在结束检查之前，您处理解析结果的模型类。或者，如果您需要帮助，请添加更多信息，例如模型类的结构，用于解析json等的代码。这里似乎没有任何内容。 Json.Net将做所有的技巧，你需要采取的唯一努力是正确建立你的类类型.. 享受编码
