How to access jsonstring in passed using viewdata in the view using jquery in c#, mvc

Question

I send json string to the view using viewdata in my mvc , c# project. this is in my controller

string getregionsforSearch = csv2json.returnJsonstringFull(getregionsPath);

            JavaScriptSerializer serializer = new JavaScriptSerializer();
            ViewData["JsonRegionList"] = serializer.Serialize(getregionsforSearch);

now I want to retrieve it in my view inside

<script></script>

and query it.how can I do that.

Data passed from the controller to the view should be kept on the ViewModel it pains me to see why people use the ViewData store. — James Dev, Apr 01 '16 at 08:42

Use Json.Encode() and @Html.Raw() as shown :-

<script>
     var data = @Html.Raw(Json.Encode(ViewData["JsonRegionList"]))
</script>

where to put `Json.Encode()` . in thre `controller` or in the `view` – bill Apr 01 '16 at 09:16
@bill..as you can see i have written the code inside `script` so it is obvious that it will be in view inside `script` tags. – Kartikeya Khosla Apr 01 '16 at 09:18
no what is the namespace for `Json.Encode` is it gives an error – bill Apr 01 '16 at 09:19
its inside `System.Web.Helpers` namespace. – Kartikeya Khosla Apr 01 '16 at 09:26

I import `System.Web.Helpers` to view and controller. it didn't work. it says the namespace json does not exist in the current context. as hints it shows `Netwonsoft.json` and another one.still exists the error – bill Apr 01 '16 at 09:47
@bill..strange...try `var data = @Html.Raw(System.Web.Helpers.Json.Encode(ViewData["JsonRegionList"]))` – Kartikeya Khosla Apr 01 '16 at 09:49
