MVC Controller 与 View 传值

Controller 到 View

1 强类型

控制器

        // GET: /Test/

        public ActionResult Index()

        {

            DateTime date = DateTime.Now;  //大部分时候使用自定义类型

            return View(date);

        }

视图

@model DateTime

@{

ViewBag.Title = "Index";

}

<h2>Index</h2>

<h2>The time is: @Model.ToString("yyyy年MM月dd日 HH:mm:ss");</h2>

<h2>The day is: @(((DateTime)Model).DayOfWeek)  </h2>

<h2>The day is: @Html.TextBoxFor(m=>m.DayOfYear)</h2>

2  ViewBag,ViewData,TempData

控制器(注意第二项,第三项输出结果)

public ActionResult TempDataTest()

        {

            TempData["Message"] = "TempData Message";

            ViewData["Message"] = "ViewData Message";

            ViewBag.Mesaage = "ViewBag Message";

            ViewBag.Info = "ViewBag Message";

            return View();

        }

视图

@{

    ViewBag.Title = "TempDataTest";

}



<h2>TempDataTest</h2>

<h2>@TempData["Message"]</h2>

<h2>@ViewData["Message"]</h2>

<h2>@ViewBag.Message</h2>

<h2>@ViewBag.Info</h2>

View 到 Controller

1 QueryString

视图

@{

    ViewBag.Title = "QueryStringTest";

}

<h2>@ViewData["Message"]</h2>



<h2>QueryStringTest</h2>



<h2> @Html.ActionLink("TestController", "QueryStringTest", new { word = "word" }) </h2>

控制器

public ActionResult QueryStringTest(string Word)

        {

            ViewData["Message"] = Request.QueryString["Word"];

            ViewData["Message1"] = Word;

            return View();

        }

2 Post

视图

@{

    ViewBag.Title = "PostTest";

}



<h2>PostTest</h2>

<h2>@TempData["Message"]</h2>

<div>

    //第一种

    <form action="/Test/PostTest" method="post">

        <ul>

            <li>用户名：<input type="text" value="" name="UserName" /></li>

            <li>密  码：<input type="text" value="" name="Password" /></li>

        </ul>

        <input type="submit" value="提交" />

    </form>

    //第二种

    @using (Html.BeginForm("PostTest", "Test", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form-horizontal", role = "form" }))

    {

        @Html.AntiForgeryToken()

        <p>

            <div class="form-group">

                @Html.Label("用户名", new { @class = "col-md-2 control-label" })

                <div class="col-md-10">

                    @Html.TextBox("username", "", new { @class = "form-control" })

                </div>

            </div>

            <div class="form-group">

                @Html.Label("密码", new { @class = "col-md-2 control-label" })

                <div class="col-md-10">

                    @Html.TextBox("Password", "", new { @class = "form-control" })

                </div>

            </div>

            <div class="form-group">

                <div class="col-md-offset-2 col-md-10">

                    <input type="submit" value="提交" class="btn btn-default" />

                </div>

            </div>

        </p>

    }

</div>

控制器

public ActionResult PostTest()

        {

            return View();

        }



        [HttpPost]

        public ActionResult PostTest(string UserName, string Password)

        {

            TempData["Message"]= "username ="+UserName +"  Password="+Password;



            return View();
