Question

I am passing an array from view to the controller using json.stringify() method.

That value is passed to the controller and is in

"\"[{\\\"id\\\":1 "id\\\":2}]\"" format. I think this is in json format, I want to convert this into {id:1,id:2} format.

I tried to convert this into string format using JsonConvert.SerializeObject(),
but it is displaying in "\"\\\"[{\\\\\\\"id\\\\\\\":1}]\\\"\"" format.

Can you tell me how can I convert into {id:1,id:2} format/integer format?

The JSON data represents an array containing a dictionary as far as I can tell. You could get hold of a Dictionary representation of the data like this:

var json = "[{\"id\":1, \"id\": 2}]";
        Dictionary<string, int>[] obj = JsonConvert.DeserializeObject<Dictionary<string, int>[]> (json);
var dict = obj[0];

I’m not sure if this is what you’re after though, since you’re saying that you want to display it like {id: 2}. If you want to print it out like that, you can build a string representation of the Dictionary:

var sb = new StringBuilder();
sb.Append("{");
foreach (var item in dict)
{
    sb.Append(string.Format("{0}: {1}, ", item.Key, item.Value));
}
sb.Remove(sb.Length - 2, 2);
sb.Append("}");
Console.WriteLine(sb.ToString());

This prints {id: 2}.

To retrieve the value for ‘id’, if this is what you mean, you can do this:

var val = dict["id"];
