Regular expression to get Url without Query string

Question

I am looking for a way to parse URL without queryString using Regular expression.

i have url like "http://abc.com/csd?/aaa/bbb"

expected is like "http://abc.com/csd"

Anybody help me on this.

System.Uri class has methods that will help you in doing such thing without regex. — Matías Fidemraizer, Sep 28 '11 at 05:54
Using a regex is probably not the best way to go, unless you're going to expand upon the use. I would simply use String.Substring(...) and String.IndexOf(...) for this. Regex is uber-slow by comparison. — cwharris, Sep 28 '11 at 05:55
When you have exact char that is delimiting your string its always better to use string methods. Regular expressions are for more advanced cases. — Piotr Auguscik, Sep 28 '11 at 05:55

If you just want everything before the query string:

^[^?]+

Regex r = new Regex("(^[^?]+)");
Match m = r.Match("http://example.com/csd?/aaa/bbb");
// m.Groups[0].Value is your URL

You could use Substring and IndexOf

var someString = "http://abc.com/csd?/aaa/bbb";
someString.Substring(0, someString.IndexOf('?') - 1);

while this does not fully comply with the requirements stated in your question, it might be an easier approach - if actual implementation does not need to be RegEx.
