我一直在寻找几天,几小时试图找到我的问题的答案。我有以下JSON字符串:
{
"id": "658@787.000a35000122",
"take": [{
"level": [0],
"status": [[3, [0]]]
}]
}
这是我需要反序列化的各种消息的示例,但它正是让我心痛的一个消息。对我来说有问题的部分是"状态"阵列。我的类接受反序列化字符串的结果是:
[DataContract]
public class ReceivedMsg
{
public ReceivedMsg()
{
move = new List<MoveOperation>();
}
[DataMember]
public string id { get; set; }
[DataMember]
public List<MoveOperation> move { get; set; }
[DataContract]
public class Status
{
[DataMember]
public int destination { get; set; }
[DataMember]
public int[] source { get; set; }
}
[DataContract]
public class MoveOperation
{
public MoveOperation()
{
status = new List<Status>();
}
[DataMember]
public int[] level;
[DataMember]
public List<Status> status { get; set; }
}
}
进行反序列化的代码是:
ReceivedMsg m = new ReceivedMsg();
m = JsonConvert.DeserializeObject<ReceivedMsg>(strResp, new JsonSerializerSettings { TraceWriter = traceWriter });
其中strResp是包含JSON数据的字符串。
我最初尝试使用作为.NET框架一部分的JSON库,但却陷入了&#34;状态&#34;一部分。是什么促使我尝试Json.NET。
我得到的错误是:
An unhandled exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in Newtonsoft.Json.dll
Additional information: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Roper.Roper+ReceivedMsg+Status' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
Path 'move[0].status[0]', line 6, position 16.
非常感谢任何帮助。当然,我很乐意根据需要提供更多信息。我尝试过做一个自定义转换器,但我认为我的C#知识还没达到那个级别。我一直试图破译为回答类似问题而提供的解决方案,但总结说我必须遗漏一些东西。
衷心感谢社区花时间阅读我冗长的问题。你的慷慨继续令我惊讶!

如果你正在使用Json.NET (如果没有,你可以使用NuGet包管理器安装它)
PM> Install-Package Newtonsoft.Json
这应该指向正确的方向:)
void Main()
{
string json = @"{
""id"": ""658@787.000a35000122"",
""take"": [{
""level"": [0],
""status"": [[3, [0]]]
}]
}";
RootObject root = JsonConvert.DeserializeObject<RootObject>(json);
}
public class Take
{
[JsonProperty("level")]
public int[] Level { get; set; }
[JsonProperty("status")]
public object[][] Status { get; set; }
}
public class RootObject
{
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("take")]
public Take[] Take { get; set; }
}
