How to populate DropDown using Json string from Web Api (MVC)

Question

I am working with API to get list of country.

Following link display JSON of countries :

http://ws.postcoder.com/pcw/PCW45-12345-12345-1234X/country?format=json

Using following code for access JSON object.

System.Net.WebClient wc = new System.Net.WebClient();
var response = wc.DownloadString("http://ws.postcoder.com/pcw/PCW45-12345-12345-1234X/country?format=json");

But I have some issues for accessing it. I want to use this response variable to populate DropDown form these countries.

Note: I am calling the API to get the list of countries.And i want to return SelectList here by using Api's response. After that i want to use this SelectList to fill DropDown on View

var jsonResponse = System.Net.WebClient.wc.DownloadString("YourApiUrl"); // you need to parse your json 
dynamic Data = Json.Decode(jsonResponse);

Suppose your api result is like {"Id":"101","Name":"Ravi Bhushan"},{"Id":"102","Name":"Abcd"} etc..

List<SelectListItem> List = new List<SelectListItem>();

foreach (var x in Data) {
   List.Add (new SelectListItem() {
      Text = x.Name,
      Value = x.Id
    });             
}
return List;// return list to view then bind your ddl with..

Now you can bind your dropdown like

@Html.DropDownList("yourDropdown", Model.List) // examples

@Html.DropDownListFor(M => M.yourDropdown, new SelectList(Model.List,"Value", "Text"))
