Construct JSON using C#

I am constructing a JSON Body for the POST method for my Odata endpoint call like below 

 Newtonsoft.Json.Linq.JObject sample;
sample = new Newtonsoft.Json.Linq.JObject();

sample["status"] = "New";
sample[ "[email protected]"] = "["+"/PROJECT('" + prjBarcode + "')"+"]";

Where [email protected] is an array. I am looking that the JSON to be built like

 "status": "New",
 "[email protected]":["/PROJECT('PJ1')"]

But with my code above it is generating like 

  "[email protected]":"[/PROJECT('PJ1')]"

Where the [] comes with in the "" how can I fix this

In JSON, square braces ([...]) denote an array, so you need to create one, for example:

var array = new Newtonsoft.Json.Linq.JArray(new string[] {"/PROJECT('" + prjBarcode + "')" });
sample["[email protected]"] = array;

You should also consider using interpolated strings, it makes your code a lot more readable:

var array = new Newtonsoft.Json.Linq.JArray(new string[] {"/PROJECT('{prjBarcode}')" });

Though, I wouldn't be building up JSON like this in the first place. You should create a concrete type to do it that matches your structure and serialise it. For example:

public class Data
{
    public string Status { get; set; }
    [JsonProperty("[email protected]")]
    public string[] Projects { get; set; }
}

var json = JsonConvert.SerializeObject(new Data
{ 
    Status = "New", 
    Projects = new string[] {$"/PROJECT('{prjBarcode}')" } 
});

You are passing string value for [email protected] key and you just need to pass an array

sample[ "[email protected]"] =  new JArray(new []{ "/PROJECT('" + prjBarcode + "')" });

or you can use another overload of JArray constructor

sample[ "[email protected]"] =  new JArray("/PROJECT('" + prjBarcode + "')");
