ASPNET MVC3技术要点

3.1

接收输入：

3.1.1 从上下文对象（context）中提取数据

{

public ActionResult Info()

// Access various properties from context objects string url = Request.Url.ToString(); string serverName = Server.MachineName; string clientIP = erHostAddress; DateTime dateStamp = HttpContext.Timestamp; string userName = ;

ViewBag.Message = string.Format("URL = {0},serverName = {1},clientIP = {2},dateStamp = {3},userName = {4}",

url, serverName, clientIP, dateStamp, userName); return View(); }

3.1.2 通过动作函数参变量传递数据。

3.1.2.1 注意参变量必须实值，参变量可以取自Request.QueryString、

Request.Form,、RouteData.Values中的值，如果要使用引用变量必须为模型变量或模型变量集合。例如：

LogOn.cshtml视图代码如下：

@model SportsStore.WebUI.Models.LogOnViewModel @{

ViewBag.Title = "Admin: Log In";

Layout = "~/Views/Shared/_AdminLayout.cshtml"; }

<h1>Log In</h1>
