.Net MVC personal note

Foreword

Wrote a .Net MVC personal notes, but not MarkDown, a pain, garden does not support previous blog articles turn MarkDown old, after a time to see if we can sort out, this time to open a new MarkDown of

Master Pages node

Write footer inside the master page

<footer>    
     @RenderSection("Footer")
</footer>

Then write in the sub-pages

@section Footer{
    <h3>大家好,我是脚</h3>
}

So that it can handle the content of the page into the node position of the master page

Controller of the data to the View mode

ViewBag and share data ViewData

 public ActionResult Index () {
     ViewBag.UserName = "小李飞刀";
     ViewData["UserName"] = "陆小凤";
     TempData["UserName"] = "楚留香"; //临时数据

     User model = new User { UserName = "谢晓峰" };

     return View (model); //这行代码其实就相当于ViewData.Model=model
 }

View Code

@{
    ViewBag.Title = "Index";
}

<div>@ViewBag.UserName </div>
<div>@ViewData["UserName"] </div>
<div>@TempData["UserName"] </div>
<div>@Model.UserName</div>

The result is:

Lu Xiaofeng

Chu Liu Xiang

Xie Xiaofeng

@model    User
