Converting JsonResult into a different object in C#

问题

So I have an object named Balance that contains:

public class Balance
{
   string balance1;
   string balance2;
   string currency;
}

and I'm trying to parse a JsonResult object that is returned by a different function call into an instance of Balance.

I've tried using JsonConvert.Serialize and Deseralize<Balance>, however, the object that I'm trying to parse into is set to null every time (ie balance1 = null etc)

Any help would be much appreciated.

EDIT:

Below is the code I'm trying to parse. Also, I realized that the data access in JsonResult is in a value called Data and shows up as Data: { balance1: "800" balance2: "800" currency: "CAD"}.

JsonResult result = admin.GetCompanyBalance(test.CustomerID, test.DevelopmentID); 
string json = JsonConvert.SerializeObject(result);
Balance br = new Balance();
br = JsonConvert.DeserializeObject<Balance>(json);

回答1:

Given your JSON:

Data: { balance1: "800" balance2: "800" currency: "CAD"}

The object you want appears to be nested inside the Data property of a parent object. You could do something like:

JObject o = JObject.parse(json);
Balance br = o["Data"].ToObject<Balance>();

回答2:

JsonResult.Data is the Balance object you are looking for.

    JsonResult result = admin.GetCompanyBalance(test.CustomerID, test.DevelopmentID);

    var balance = result.Data as Balance;

Or if you want to test the serialization and deserialization you can do

    var json = JsonConvert.SerializeObject(result.Data);   

    var br = JsonConvert.DeserializeObject<Balance>(json);
