I've seen similar questions and answers regarding conversions from virtual to absolute and url, but how can I convert a url to a virtual path without manual string parsing?
Example:
I want "http://myserver/home.aspx" converted to: "~/home.aspx"
I realize the above example would be an easy string parsing routine, but I'm looking for a proper solution that will scale to the changing of the url format.
You can get most of it from the Uri class:
new Uri("http://myserver.com/home.aspx").AbsolutePath
Then you just have to prepend the ~
Though, that will might break if you host in a subdirectory - I don't think there's a way to do it specifically in the context of the application you're running.
EDIT: This might do it:
VirtualPathUtility.ToAppRelative(new Uri("http://myserver.com/home.aspx").AbsolutePath);
VirtualPathUtility.ToAppRelative Method (String) seems to be what you are looking for (http://msdn.microsoft.com/en-us/library/ms150163.aspx)
If the virtual path for the application is "myapp" and the virtual path "/myApp/sub/default.asp" is passed into the ToAppRelative method, the resulting application-relative path is "~/sub/default.aspx".
