Return View detailed MVC

1, return View ();

return value

Type: System.Web.Mvc.ViewResult
Renders the view to the response's View() result. 

NotesThis method overload of the View () class returns a ViewResult object with an empty ViewName property. If you are writing unit tests for controller actions, consider the empty ViewName property for unit tests that do not take a string view name.

At run time, if the ViewName property is empty, the ViewName property will be replaced with the current operation name.

2, return View (object  model);  

Parameters

Model

the model that the view renders.

Return value type: System.Web.Mvc.ViewResult

The action we see above is the return View (), which we can consider as the return value used to parse an ASPX file. And its return type is actionresult as

      Public ActionResult Index ()        {            return View ();        }

Besides view () what value can we use here to return?

I. ASCX page

Scenario: To return a snippet, such as Ajax, to return a sub-page

Let's start with a new action

        Public ActionResult Ascx ()        {            return Partialview ();        }

We'll build a view below, still in action, right-click, AddView.

Note the picture is checked.

So I created an ascx page, and we're going to rewrite it a little bit.

<%@ Control language= "C #" inherits= "System.Web.Mvc.ViewUserControl"%><div> get a div</div>

Run, get the page

Second, return text

In addition to the above, we sometimes return only a piece of text.

At this point we can use the following action form:

        Public ActionResult text () {            return Content ("This is a piece of text");        }

Third, return JSON

Sometimes when we call Ajax we also ask that the returned object be the result of JSON serialization, such as:

        Public ActionResult Showjson ()        {            var m = new Eiceindexmodel            {                Name = "Kingjian",                Sex = True            };            Return Json (m);        }

Return text:

{"Name": "Kingjian", "Sex": true}

Iv. Output JS file

Most of the time JS files are static, but sometimes JS files may also be generated dynamically at this point we can output

        Public ActionResult Js ()        {            return JavaScript ("var x=0;");        }

We visit, get a normal page but its content-type:application/x-javascript; Charset=utf-8

Five, page jump

1. Jump to URL

        Public ActionResult Rdurl ()        {            return Redirect ("http://www.baidu.com");        }

2. Jump to Action

        Public ActionResult rdaction ()        {            return redirecttoaction ("Index", "Eice");        }

3. Jump to Routing Rule

        Public ActionResult rdrouting ()        {            return Redirecttoroute ("Default",//route name              new{                  Controller = "Eice ",                  Action =" Index "              });        

Vi. Display Files

        Public actionresult fn ()        {            return file (                "/content/site.css"//File path                , "text/css"//file type                );        }
