Extract Url from Javascript in

Question

I am new in Regex can you please help in writing for regex in C# to extract url from text below?

Example 1

x+=1;
top.location.href = "http://www.keenthemes.com/preview/index.php?theme=metronic";

Example 2

alert("are you sure");     
top.location.href   = 'http://www.keenthemes.com/preview/index.php?theme=metronic';

Are you looking to get www.keenthemes.com from the above URL in C# ? or you want to get the string which starts with http ? — Habib

If the URL always starts with http://, this one should do it:

["'](http.*)["']

The URL is stored in the second group (Groups[1].Value) of the Match object
