ASP.NET MVC 3 直到我膝盖中了一箭【4】小试牛刀

1.创建一个asp.net mvc 3 项目-->选择razor视图引擎

2.~/models/下添加类studentmodels-->重新生成解决方案

3.~/controllers/下添加控制器studentcontroller-->添加index视图

4.global.asax 文件中设置全局 url 路由默认值

1             routes.ignoreroute("{resource}.axd/{*pathinfo}"); // 要忽略的路由的url模式直接访问.axd文件
2             routes.maproute(
3                 "default", // 路由名称
4                 "{controller}/{action}/{id}", // 带有参数的 url
5                 new { controller = "student", action = "index", id = urlparameter.optional } // 参数默认值
6             );
5.未将对象引用设置到对象的实例

 1         public actionresult index()
 2         {
 3             return view(getdata());
 4         }
 5
 6         /// <summary>
 7         /// 初始化
 8         /// </summary>
 9         /// <returns></returns>
10         ienumerable<studentmodels> getdata()
11         {
12             ienumerable<studentmodels> list = new list<studentmodels>
13                            {
14                                new studentmodels() {id = 1001, name = "张三", age = 20},
15                                new studentmodels() {id = 1002, name = "李四", age = 21},
16                                new studentmodels() {id = 1003, name = "王五", age = 22}
17                            };
18             return list;
19         }
6.详细信息-->添加details视图

 1         public actionresult details(int id)
 2         {
 3             foreach (var student in getdata())
 4             {
 5                 if (student.id.equals(id))
 6                 {
 7                     return view(student);
 8                 }
 9             }
10             return view();
11         }
7.创建-->添加create视图

 1         public actionresult create()
 2         {
 3             return view();
 4         }
 5         [httppost]
 6         public actionresult create(formcollection collection)
 7         {
 8             try
 9             {
10                 return redirecttoaction("index");
11             }
12             catch
13             {
14                 return view();
15             }
16         }
8.更新-->添加edit视图

 1         public actionresult edit(int id)
 2         {
 3             return view();
 4         }
 5         [httppost]
 6         public actionresult edit(int id, formcollection collection)
 7         {
 8             try
 9             {
10                 return redirecttoaction("index");
11             }
12             catch
13             {
14                 return view();
15             }
16         }
9.删除-->添加delete视图

 1         public actionresult delete(int id)
 2         {
 3             foreach (var student in getdata())
 4             {
 5                 if (student.id.equals(id))
 6                 {
 7                     return view(student);
 8                 }
 9             }
10             return view();
11         }
12         [httppost]
13         public actionresult delete(int id, formcollection collection)
14         {
15             try
16             {
17                 // todo: add delete logic here
18 
19                 return redirecttoaction("index");
20             }
21             catch
22             {
23                 return view();
24             }
25         }

10.开始执行
