URL路由在ASP .Net MVC2中不起作用

Question

I am working ASP.Net MVC2 application. In that i have used URL Routing

To get URL as

    https://localhost/StudentDetail/SortField

I have written below code in Global.asax

routes.MapRoute(
"StudentDetail", // Route name
"StudentDetail/{SortField}", // URL with parameters
new { controller = "UDashboard", action = "UAboutMeStudentDetails", 
     SortField = "Major" }
);

And In my view link is as below

<a href="/StudentDetail?SortField='Major'" >Students</a>

But it is not working. and my URL is

https://localhost/StudentDetail?SortField='Major'

Can anyone please help me to get the required URL..?

I want URL as

https://localhost/StudentDetail/SortField

Thanks In Advance, Prashant

I think you have an incorrect thought on how routing works. Your route:

routes.MapRoute(
"StudentDetail", // Route name
"StudentDetail/{SortField}", // URL with parameters
new { controller = "UDashboard", action = "UAboutMeStudentDetails", 
     SortField = "Major" }
);

Will take the SortFeild parameter (Major, Gpa, etc), and replace {SortField} with that value. So, using the following actionlink:

@Html.ActionLink("Student Details", "UAboutMeStudentDetails", new {controller="UDashboard", SortField = "Major}) 

would produce the following HTML

<a href="/StudentDetail/Major">Student Details</a>

Note that the value of SortField has replaced the {SortField} parameter in your route. You would never get a URL looking like what you are requesting as how would you get the value of SortField to the action?
