want to know about the RegularExpression class of C#

• IsMatch - Checks if a string, or part of the string specified in the parameters matches the regular expression provided in the constructor.
• Match - Returns a match object which contains the first match that the class found matching the regular expression.
• Matches - Returns a collection of Match objects for each regular expression matched correctly.

// Must include: System.Text.RegularExpressions namespace

string urls = "there is a url included somewhere in this string : http://www.codeproject.com/script/comments/forums.asp?msg=1524600&forumid=1649#xx1524600xx and here is another url http://regexlib.com/Search.aspx?k=uri";
