How to convert an embedded JSON string to a JSON Object in C#

Question

I have a function that returns data as a json string and I am calling that string inside my api but I want my api to return a json object instead of a json string.

This is what the function looks like:

   public JObject InquiryPaymentAPI(string id)
        {
           
            string paymentInfo = PaymentInquiry.IPayment(id);
            return JObject.Parse(paymentInfo);

        }

This returns a json object but the embedded part looks like an empty array how do I get it to return all the data please help I am new to c#

{
    "paymentId": [],
    "paymentRequestId": [],
    "paymentAmount": [
        [
            []
        ],
        [
            []
        ]
    ],
    "paymentStatus": [],
    "result": [
        [
            []
        ],
        [
            []
        ],
        [
            []
        ]
    ]
}

Answer 1

If you know the json response, you can create a model class for it. On VS 2022 you can right click on editor and do paste special Edit --> Paste special --> Paste JSON as Classes. You should get something like below.

public class Model 
{
    public object[] paymentId { get; set; }
    public object[] paymentRequestId { get; set; }
    public object[][][] paymentAmount { get; set; }
    public object[] paymentStatus { get; set; }
    public object[][][] result { get; set; }
}

After using that Model class in your code, your code should look like below

using System.Text.Json;

public Model InquiryPaymentAPI(string id)
{
   
    string paymentInfo = PaymentInquiry.IPayment(id);
    return JsonSerializer.Deserialize<Model>(paymentInfo);

}
