4 Routes. mappageroute (
5 " Defautl " ,
6 "" ,
7 " ~ /Folder1/webform1.aspx "
8 );

10 // Route URLs in the form of {folder}/{webform}
11 Routes. mappageroute (
12 " Webform1 " ,
13 " {Folder}/{webform} " ,
14 " ~ /{Folder}/{webform}. aspx "
15 );

17 // Route URLs in the form of {folder}/{page} (with parameters)
18 Routes. mappageroute (
19 " Webform2 " ,
20 " {Floder}/{webform}/{parameter} " ,
21 " ~ /{Floder}/{webform}. aspx "

24 }

3. Use the registerroute method in the application_start method.

1 Protected   Void Application_start ( Object Sender, eventargs E)
2 {
3 Registerroutes (routetable. routes );

To obtain parameters in the URL, refer to the followingCode 

1 String Parameter = Page. routedata. Values [ " Parameter " ] As   String ;

It obtains the parameter with the placeholder parameter. For example ~ The parameter value of/folder2/webform3/ABC can be obtained, but if ~ /Folder2/webform3? Parameter = ABC does not seem to get the parameter value of parameter. Available

1 String Parameter = Request. Params [ " Parameter " ] As   String ;
