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", "[email protected]", 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(); }
