RegEx匹配URL中第一个反斜杠后的所有内容

Question

I need help trying to figure out the regex to match only what is after the first backslash in a url.

URL Example: http://www.TestThis.com/Some-Data/Some-Other-Data/Even-More-Data

Pattern: ^(.*?//.*?/)(.*)$

I get 2 matches, which can work, but I really only want what is after the http://www.TestThis.com/

Answer 1

Uri.PathAndQuery is better approach than any regEx you can come up with for valid Urls. It will also handle cases of IP instead of DNS name, % encoding used in host portion, ports and like.

 Console.Write(
    new Uri(
     "http://www.TestThis.com/Some-Data/Some-Other-Data/Even-More-Dat"
    ).PathAndQuery);

Answer 2

You could try it without regex:

string test = "http://www.TestThis.com/Some-Data/Some-Other-Data/Even-More-Data";
string intermediate = test.Split(new string[] { "//" }, StringSplitOptions.RemoveEmptyEntries)[1];
string final = intermediate.Substring(intermediate.IndexOf('/') + 1);
