pass dictionary to controller asp.net mvc

Question

I am wanting to pass a dictionary of type to my controller via an Ajax post. The main reason here is the post may have between 1-3 key value pai

Answer 1

Client (JavaScript):

var dict = new Object();
dict.Key1 = "Value1"
dict.Key2 = "Value2"

$.post('/YourController/YourAction/', dict);

NOTE: The "dict" objects gets serialized behind the scenes before being sent to your action.

Server:

public ActionResult YourAction()
{
    string postData = string.Empty;
    using (StreamReader sr = new StreamReader(Request.InputStream))
    {
        postData = sr.ReadToEnd();
    }    

    //Load post data into JObject (Newtonsoft.Json)
    JObject o = JObject.Parse(postData);

    //Extract each key/val 
    string val1 = (string)o["Key1"];

    //Do whatever....
}
