Retrieve an email-id from url
<p>I have an page where I am embedding email-id of the user into the url and sending him mail 
now I want to extract the email from the url and match the value with the database. My question is how do I retrieve that email from that url?</p>

<pre><code>string url = "http://localhost:3063/user/Authenticate-Users.aspx?"+emailfield;
</code></pre>

<p>this is the url...</p>
