来自Web API的自定义Json响应

Question

I am working on ASP .Net web api project where we are giving response of a custom object. JsonFormatter formats the data to a json object when api is exposed in fiddler. Here is the skeleton of our application.

Data Objects

public class CustomData
{
  public Records MRecord {get;set;}
  public string ResponseCode {get;set;}
  public string Status {get;set;}
}

public class Records
{
  Public class FirstName {get;set;}
  Public class LastName {get;set;}
}

Response

CustomData : {
  MRecord : [
   {
     FirstName : "1stName",
     LastName : "",
   },
   {
     FirstName : "2Name",
     LastName : "",
   },
 ],
 ResponseCode : "0",
 Status: "Success"
}

And the expected format is like

CustomData : {
    MRRecordList : {
      MRecord : 
       {
         FirstName : "1stName",
         LastName : "",
       },
      MRecord :
       {
         FirstName : "2Name",
         LastName : "",
       }
     },
     ResponseCode : "0",
     Status: "Success"
    }

Considering the array objects aren't split and shown as a single entity by the JsonFormatter. Please help me if there is any solution to achieve this.

Answer 1

Following is the code / model you need:

void Main()
{
    var c = new CustomData()
    {
        MRecordList = new List<UserQuery.Record>
        {
          new Record{FirstName="A",LastName="B"},
          new Record{FirstName="C",LastName="D"}
        },
        ResponseCode = "0",
        Status = ""     
    };

    JsonConvert.SerializeObject(c).Dump();
}


public class CustomData
{
    public List<Record> MRecordList { get; set; }
    public string ResponseCode { get; set; }
    public string Status { get; set; }
}

public class Record
{
    public string FirstName { get;set;}     
    public string LastName { get;set;}
}

This will yield the following Json:

{
    "MRecordList": [{
        "FirstName": "A",
        "LastName": "B"
    }, {
        "FirstName": "C",
        "LastName": "D"
    }],
    "ResponseCode": "0",
    "Status": ""
}

In case your requirement is the following Json:

{
    "customData": {
        "MRecordList": [{
            "FirstName": "A",
            "LastName": "B"
        }, {
            "FirstName": "C",
            "LastName": "D"
        }],
        "ResponseCode": "0",
        "Status": ""
    }
}

then make following changes to the code:

public class Test
{
    public CustomData customData {get;set;}
}

Test t = new Test{customData = c};

Now serialize t

Remember no root tag in Json as clear from the above examples
