1.创建UrlHelper类的扩展方法,生成相对路径URL
请避免将控制器、行为、或者路由名称作为字符串到处传递,创建UrlHelper的扩展方法来封装它们,例如:
1. public static class UrlHelperExtension
2. {
3. public static string Home(this UrlHelper helper)
4. {
5. return helper.Content("~/");
6. }
7.
8. public static string SignUp(this UrlHelper helper)
9. {
10. return helper.RouteUrl("Signup");
11. }
12.
13. public static string Dashboard(this UrlHelper helper)
14. {
15. return Dashboard(helper, StoryListTab.Unread);
16. }
17.
18. public static string Dashboard(this UrlHelper helper, StoryListTab tab)
19. {
20. return Dashboard(helper, tab, OrderBy.CreatedAtDescending, 1);
21. }
22.
23. public static string Dashboard(this UrlHelper helper, StoryListTab tab, OrderBy orderBy, int page)
24. {
25. return helper.RouteUrl("Dashboard", new { tab = tab.ToString(), rderBy = orderBy.ToString(), page });
26. }
27.
28. public static string Update(this UrlHelper helper)
29. {
30. return helper.RouteUrl("Update");
31. }
32.
33. public static string Submit(this UrlHelper helper)
34. {
35. return helper.RouteUrl("Submit");
36. }
37. }
这样的话,您就可以在视图中这样来使用:
1. <a href="<%= Url.Dashboard() %>">Dashboard</a>
2. <a href="<%= Url.Profile() %>">Profile</a>
而不是这样:
1. <%= Html.ActionLink("Dashboard", "Dashboard", "Story") %>
2. <a href="<%= Url.RouteUrl("Profile")%>">Profile</a>
并且在控制器中我能这么用:
1. return Redirect(Url.Dashboard(StoryListTab.Favorite, OrderBy.CreatedAtAscending, 1))
而不是这样:
1. return RedirectToAction("Dashboard", "Story", new { tab = StoryListTab.Favorite, rderBy = OrderBy.CreatedAtAscending, page = 1 });
