HtmlHelper用來在檢視中呈現 HTML 控制元件，主要分為以下幾類：
1.ActionLink - 連結到操作方法
1 @Html.ActionLink("這是一個連線", "Index", "Home")
2 帶有QueryString的寫法
3 @Html.ActionLink("這是一個連線", "Index", "Home", new { page=1 },null)
4 @Html.ActionLink("這是一個連線", "Index", new { page=1 })
5 有其它Html屬性的寫法
6 @Html.ActionLink("這是一個連線", "Index", "Home", new { id="link1" })
7 @Html.ActionLink("這是一個連線", "Index",null, new { id="link1" })
8 QueryString與Html屬性同時存在
9 @Html.ActionLink("這是一個連線", "Index", "Home", new { page = 1 }, new { id = "link1" })
10 @Html.ActionLink("這是一個連線", "Index" , new { page = 1 }, new { id = "link1" })
