WCF REST Web服务-Json的反序列化

Question

I am encountering a problem on my WCF web service. I have this error:

The server encountered an error processing the request.

I think is due to the deserialization of the JSON, I will past my code, please give me some help, thank you.

Here is the raw JSON:

{
"properties" : {
    "callID" : "4A79825AE0914B6B9B27F477CAF8A32B",
    "timestamp" : "2018-06-05T08:50:41.064+0000",
    "data" : {
      "Name" : "Y",
      "Surname" : "X",
      "Age" : [ "25" ]
    },
    "localEvent" : "X",
    "eventtype" : "X"
   }                                                                            
}

And i have the following classes:

public class CSModel
{
    public CSProperties properties { get; set; }
}

public class CSProperties
{
    public string callID{ get; set; }
    public string timestamp{ get; set; }
    public CSData DataModel { get; set; }
    public string localEvent{ get; set; }
    public string eventtype{ get; set; }
}
    public class CSData
{
    public string Name{ get; set; }
    public string Surname{ get; set; }
    public string Age{ get; set; }
}

And here i decode my JSON:

string jsonBody = new StreamReader(contents).ReadToEnd();
CSModel jsonModel = JsonConvert.DeserializeObject<CSModel>(jsonBody);

There are couple of things which you need to change, since your C# class representation isn't correct

1. Use attributes ( [JsonProperty(ProperyName = "data")] ) to decorate class properties which have different name than the name in the JSON itself. If you don't do that, your DataModel property will remain null.

2. "Age" property holds value of string array type, which means you need to change C# property into string[] . This must be changed to prevent exceptions due to type mismatch
