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();
}
