无废话版本-Asp.net MVC4.0 Rasor的基本用法

最近工作有点忙，好久没写东西了！废话不多说了，进入主题！

1.在页面中输出单一变量时候，只要在C#语句之前加上@符号即可，For example：

<p>Now Time：@DateTime.Now</p>

请注意，上述example中虽然使用C#语言撰写代码，但输出单一变量的时候，不需要加上分号；

2.在页面上输出一段含有空白字元或者运算子的结果时，必须在前后加上一个小括号，For example：

<p>
UserName：@(User.Identity.Name+Model.Member)
State        :@(ViewBag.IsEnabled?"启用"："停用")
</p>

　　--前台页面

@{
    Layout = null;
}
@{
    var htmlAttribute = ViewData["Dictionary"] as IDictionary<string, object>;
}

<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Rasor</title>
</head>
<body>
    <h1>Rasor基本语法</h1>
    <div>
        @using (Html.BeginForm("About", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
        {
            @Html.TextBox("Field", " ", new { type = "file", @class = "ed", size = "25" })<br />
            @Html.Password("Pwd", "", htmlAttribute)<br />
            @Html.TextBox("Email", "133030@qq.com", htmlAttribute)<br />
            @Html.Hidden("Hidden", "Value", htmlAttribute)<br />
            @Html.DropDownList("List",ViewData["List"] as SelectList,"请选择")
        }
    </div>
</body>
</html>

　　后台方法：

public ActionResult Rasor()
        {
            IDictionary<string, object> attr = new Dictionary<string, object>();
            attr.Add("size","32");
            attr.Add("style","color:red");
            ViewData["Dictionary"] = attr;
            //DropdwonList的用法
            List<SelectListItem> list = new List<SelectListItem>();
            list.Add(new SelectListItem { Text="中国",Value="1"});
            list.Add(new SelectListItem { Text = "美国", Value = "2" });
            list.Add(new SelectListItem { Text = "俄国", Value = "3" });
            ViewData["List"] = new SelectList(list, "Value", "Text", "");
            return View();
        }
