how to manipulate the URL path in c# asp.net?

Question

I have the following path:

-http://localhost/portal/reportview.aspx

but I need to retrieve the first 3 parts:

-http://localhost/portal/

Ive tried HttpContext.Current.Request.Url.GetLeftPart(); with no luck.

Answer 1

You can use substring.

string str = "http://localhost/portal/reportview.aspx";

string left = str.Substring(0, str.LastIndexOf("/"));

Answer 2

Try this;

string s = "http://localhost/portal/reportview.aspx";
string y = string.Format("{0}//{2}/{3}/",s.Split('/'));
