JSON error with \r\n in C# string

I'm working with php on the backend and C# on client side. So when I receive multiline message from server in JSON I do this:

dynamic answer = JsonConvert.DeserializeObject(resultHttpPost);
string body = answer.body;

But I'm getting an error:

Symbol of new line is in constant

Because of this I can't use multilines messages.

I tried like this and it didn't work either

resultHttpPost = resultHttpPost.Replace("\\n", "\n").Replace("\\r", "\r").Replace("\\t", "\t");
  project.Variables["var_dump"].Value = resultHttpPost;
dynamic answer = JsonConvert.DeserializeObject(resultHttpPost);

So how do I make it work?

Example for JSON:

{"status":"response_ok","message":{"body":"Hi test,\r\n\r\ntesting it, lorem ipsum lorem ipsumlorem ipsumlorem ipsumlorem ipsum.\r\n\r\nSignature","id":1015,"id_thread":741},"id_thread":741}

I notice you're using this with ASP.NET.

It is most likely because you are actually serializing it twice. In my case, I was calling Json.NET's serialize method and then the resulting string was being returned from a Web API controller and that itself was serializing the JSON string (ASP.NET Web API internally uses Json.NET) and serializing JSON into JSON results in the \r\n appearing everywhere.

Example code:

using System;
using System.Collections.Generic;
using Newtonsoft.Json;

public class Message
{
    public string body { get; set; }
    public int id { get; set; }
    public int id_thread { get; set; }
}

public class RootObject
{
    public string status { get; set; }
    public Message message { get; set; }
    public int id_thread { get; set; }
}

public class Program
{
    static public void Main()
    {
        string j = "{\"status\":\"response_ok\",\"message\":{\"body\":\"Hi test,\r\n\r\ntesting it, lorem ipsum lorem ipsumlorem ipsumlorem ipsumlorem ipsum.\r\n\r\nSignature\",\"id\":1015,\"id_thread\":741},\"id_thread\":741} ";

        RootObject ro = JsonConvert.DeserializeObject<RootObject>(j);

        Console.WriteLine(ro.message.body);
    }

}

Result:

Hi test,

testing it, lorem ipsum lorem ipsumlorem ipsumlorem ipsumlorem ipsum.
