How can i get back the encoded value in a sql string?

Question

I have an email as follows:

    [email protected]

Now when i make a call and pass it as a parameter i do the following

HttpUtility.UrlEncode(email) in order to get the + sign.

But when i receive the email in the procedure , it is now

  test+user1%40test.com

I have tried HttpUtility.UrlEncode, but i no longer have the @ sign

and when i try to search my table , it cant find it.

My search is as follows:

" SELECT ......... where Email like '%' + @Email + '%' ";

So how can i get it back to [email protected] ?
