I am using @Html.Action to call contoller action to return a string. I want to save the string to a variable inside razor as it is comma-seperated. 

```
@Html.Action("GetCategories", new { SP = @ViewBag.Name, SD = "Cad" }).ToString();
//@String s = save above string in here
//@string[] arrS = s.Split(','); 

@String test = @Html.Action(......) //tried this but does NOT work.

Public ActionResult GetCategories(string SP, string SD)
{
  //Code missing
  return Content(return "sugar");
}

```

How can I save the Html.Action returned data to a string ?
