How to validate URL using Regular expression with query string?

Question

Please do read full question before marking it duplicate.

I want to validate URL which can contain query string. I found some of the solutions. But It is not working for me. Examples of valid URLs for me are:
1)http://www.example.com/
2)www.example.com
3)example.com
4)http://www.exaple.com/test2/aa.aspx?id=2&sad=ss

I have used following expression:
1) ^((http|https)://)?([\w-]+\.)+[\w]+(/[\w- ./?]*)?$

But when I used this expression Query string were not allowed.

2) (http|ftp|https)://([\w+?\.\w+])+([a-zA-Z0-9\~\!\@\#\$\%\^\&\*_\-\=\+\\\/\?\.\:\;\'\,]*)?
But in this http is required. If i enter URL like: google.com this expression says it is not valid.

Can anyone help me to validate this?
Thank you in advance.

Why don't you try Uri.[TryCreate](http://msdn.microsoft.com/en-us/library/system.uri.trycreate.aspx) to validate the uri. — Rohit Prakash, Jan 20 '15 at 09:02
Even the most basic regex knowledge should let you change your second expression to make the protocol identifier optional... — thebjorn, Jan 20 '15 at 09:02

Your second query is good. Not sure why you cannot modify it to suit your need. — Zaid Amir, Jan 20 '15 at 09:39

Below expression worked for me. Please try this:

^((http|https|ftp|www):\/\/)?([a-zA-Z0-9\~\!\@\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,]*)(\.)([a-zA-Z0-9\~\!\@\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,]+)

It matches `http://wwwhttp://wwww.fff`, for a start. And `.www`. And `.www/.?&&&&&&`. – Rawling Jan 20 '15 at 10:17
