Convert C# Object to Json Object

Question

I am trying to serialize a C# object into a Json object. That will then be submitted to the Salesforce API, and create an application. Right now I have the C# object serialized into a Json string, but I need it to be an object.

Here is my C# object along with accompany serialization.

Customer application = new Customer { 
    ProductDescription = "gors_descr " + tbDescription.Text, 
    Fname = "b_name_first " + tbFName.Text, 
    Lname = "b_name_last " + tbLName.Text
};

var json = new System.Web.Script.Serialization.JavaScriptSerializer();
string jsonString = json.Serialize(application);

string endPoint = token.instance_url + "/services/apexrest/submitApplication/";    
string response = conn.HttpPost(endPoint, json, token);
Literal rLiteral = this.FindControl("resultLiteral") as Literal;

I need the JSON string to output inside of a JSON Object. An example of what I need is below:

"{ \"jsonCreditApplication\" : " +
    "\"gors_descr\" : \"Appliances\", " +
    "\"b_name_first\" : \"Marisol\", " +
    "\"b_name_last\" : \"Testcase\", " +
"}"; 

This hard coded json string is inside of an object. As it stands, the values in the C# object are being outputted into a JSON string, but I'm needing it output into an object so that the Salesforce API will accept the submission.

How can I append or insert the JSON string into an object?

Answer 1

using System; 
using Newtonsoft.Json; 
using Newtonsoft.Json.Linq;

CurrentUTCDateTime yourObject = new CurrentUTCDateTime(); 
JObject json = JObject.Parse(JsonConvert.SerializeObject(yourObject));

To create correct JSON first you need to prepare appropriate model. It can be something like that:

[DataContract]
public class Customer
{
    [DataMember(Name = "gors_descr")]
    public string ProductDescription { get; set; }

    [DataMember(Name = "b_name_first")]
    public string Fname { get; set; }

    [DataMember(Name = "b_name_last")]
    public string Lname { get; set; }
}

To be able to use Data attributes you will need to choose some other JSON serializer. For example DataContractJsonSerializer or Json.NET(I will use it in this example).

Customer customer = new Customer
{
    ProductDescription = tbDescription.Text,
    Fname = tbFName.Text,
    Lname = tbLName.Text
};


string creditApplicationJson = JsonConvert.SerializeObject(
    new
    {
        jsonCreditApplication = customer
    });

So jsonCreditApplication variable will be:

{
  "jsonCreditApplication": {
    "gors_descr": "Appliances",
    "b_name_first": "Marisol",
    "b_name_last": "Testcase"
  }
}

Answer 3

Install Newtonsoft.Json NuGet then decorate Customer class with the requires naming decorations to tell Json serializer how to serialize the customer class fields:

public class Customer
{
    [JsonProperty("gors_descr")]
    public string ProductDescription;
    [JsonProperty("b_name_first")]
    public string Fname;
    [JsonProperty("b_name_last")]
    public string Lname;
}

Next, serialize the object like this:

Customer application = new Customer
        {
            ProductDescription = "Appliances ",
            Fname = "Marisol ",
            Lname = "Testcase "

        };
        var JsonOutput = JsonConvert.SerializeObject(new { jsonCreditApplication = application });

You will get the desired result and the value of JsonOutput will be : "{\"jsonCreditApplication\":{\"gors_descr\":\"Appliances \",\"b_name_first\":\"Marisol \",\"b_name_last\":\"Testcase \"}}"

There are many ways to do this but I believe that this one is the simplest solution.
