    Let us learn in brief about each ActionResult are as

    ViewResult

    public ActionResult Index()
    {
        return View();
    }
}
    PartialViewResult 
     It returns the partial view to the response stream,mostly the partial view call from main view.Its same like as user control in Asp.net.
    Syntax
    public class EmpController : Controller
{
    
    public ActionResult Index()
    {
        return PartialView("_Empdetails");
    }
}
    EmptyResult  
    This action returns the empty response to the client.
    Syntax  
    public class EmpController : Controller
{
    
    public ActionResult Index()
    {
      return new EmptyResult();
    }
}
    • RedirectResult -It redirects to the specified url same as Response.Redirect in Asp.net.
     Syntax 
    public class EmpController : Controller
{
    
    public ActionResult Index()
    {
     return Redirect("http://www.compilemode.com");
    }
}
    • RedirectToRouteResult - Performs an HTTP redirection to a URL that is determined by the routing engine, based on given route data.
    Syntax 
    public class EmpController : Controller
{
    public ActionResult Index()
    {
    filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new { 
    action = "View", 
    controller = "EmpController",}));
    }
}
    JsonResult
    This action Serializes a given View Data object into JSON (JavaScript object notation) format.
    Syntax  
    public class EmpController : Controller
{
    public JsonResult EmpDet()  
        {  
     
            return Json("HI", JsonRequestBehavior.AllowGet);  
        }   
   
}
    JavaScriptResult 
    This action returns a piece of JavaScript code that can be executed on the client side.
    Syntax 
    public class EmpController : Controller
{
public virtual JavaScriptResult EmpDet()

    var script = string.Format(@"
    MaxNotificaitonsToShow = {0};
    ItemsPerPage = 5;",
    GlobalSettings.MaxNotificaitonsToShow);
    return JavaScript(script);
}
}
    ContentResult 
    It writes content to the response stream without requiring a view.
    Syntax

    return Content("Hi Vithal Wadje");
}
}
    FileContentResult

    string contentType = "application/pdf";
 
    return new FilePathResult(fileName, contentType);
}
}
    FileStreamResult
