有Index視圖如下：

視圖代碼如下：

[html] view plaincopy

如圖填寫表單數據：

分別使用不同的表單處理方法，對提交的表單數據在視圖FormResults呈現。

提交表單對應的HomeController，包含以不同方法獲取表單數據的代碼，如下：

[csharp] view plaincopy

using?System;??

using?System.Collections.Generic;??

using?System.Linq;??

using?System.Web;??

using?System.Web.Mvc;??

??

namespace?HtmlHelper.Controllers??

{??

????[HandleError]??

????public?class?HomeController?:?Controller??

????{??

????????public?ActionResult?Index()??

????????{??

????????????ViewData["Message"]?=?"歡迎使用?ASP.NET?MVC!";??

??

????????????//手動構造頁面中下拉框的寵物數據??

????????????List<string>?petList?=?new?List<string>();??

????????????petList.Add("Dog");??

????????????petList.Add("Cat");??

????????????petList.Add("Hamster");??

????????????petList.Add("Parrot");??

????????????petList.Add("Gold?fish");??

????????????petList.Add("Mountain?lion");??

????????????petList.Add("Elephant");??

??

????????????ViewData["Pets"]?=?new?SelectList(petList);??

??

????????????return?View();??

????????}??

??

????????public?ActionResult?About()??

????????{??

????????????return?View();??

????????}??

??

????????///?<summary>??

????????///?處理表單提交數據，方法1:使用傳統的Request請求取值??

????????///?</summary>??

????????///?<returns></returns>??

????????public?ActionResult?HandleForm()??

????????{??

????????????ViewData["name"]?=?Request["name"];??

????????????ViewData["favColor"]?=?Request["favColor"];??

????????????ViewData["bookType"]?=?Request["bookType"];??

????????????ViewData["pet"]?=?Request["pets"];??

??

????????????return?View("FormResults");??

????????}??

??

????????///?<summary>??

????????///?處理表單提交數據，方法2:Action參數名與表單元素name值一一對應??

????????///?</summary>??

????????///?<param?name="name"></param>??

????????///?<param?name="favColor"></param>??

????????///?<param?name="bookType"></param>??

????????///?<param?name="pets"></param>??

????????///?<returns></returns>??

????????//public?ActionResult?HandleForm(string?name,?string?favColor,?Boolean?bookType,?string?pets)??

????????//{??

????????//????ViewData["name"]?=?name;??

????????//????ViewData["favColor"]?=?favColor;??

????????//????ViewData["bookType"]?=?bookType;??

????????//????ViewData["pet"]?=?pets;??

??

????????//????return?View("FormResults");??

????????//}??

??

????????///?<summary>??

????????///?處理表單提交數據，方法3:從MVC封裝的FormCollection容器中讀取??

????????///?</summary>??

????????///?<param?name="form"></param>??

????????///?<returns></returns>??

????????//public?ActionResult?HandleForm(FormCollection?form)??

????????//{??

????????//????ViewData["name"]?=?form["name"];??

????????//????ViewData["favColor"]?=?form["favColor"];??

????????//????ViewData["bookType"]?=?form["bookType"];??

????????//????ViewData["pet"]?=?form["pets"];??

??

????????//????return?View("FormResults");??

????????//}??

??

????????///?<summary>??

????????///?處理表單提交數據，方法4:使用實體作為Action參數傳入，前提是提交的表單元素名稱與實體屬性名稱一一對應??

????????///?</summary>??

????????///?<param?name="request"></param>??

????????///?<returns></returns>??

????????//[HttpPost]??

????????//public?ActionResult?HandleForm(InforModel?infor)??

????????//{??

????????//????ViewData["name"]?=?infor.name;??

????????//????ViewData["favColor"]?=?infor.favColor;??

????????//????ViewData["bookType"]?=?infor.bookType;??

????????//????ViewData["pet"]?=?infor.pets;??

??

????????//????return?View("FormResults");??

????????//}??

??

????}??

}??

在FormResults視圖顯示ViewData的數據，如圖所示：
