Send out Registration Emails in CreateUserWizard

My website allow user to create account.

Upon creating, a email verification with a URL will be send to the user's email.

Problem: The sending of email worked but unfortunately the verification URL did not appear.


And for

<a href="<%VerifyUrl%>"<%VerifyUrl%></a></p> 

there is a green curly line beneath "<%VerifyUrl%>", stating that this file could not be found.

File <%VerifyUrl%> was not found

This is the source code of Login.aspx :

protected void CreateUserWizard1_SendingMail(object sender,MailMessageEventArgs e)
{
    MembershipUser userInfo = Membership.GetUser(CreateUserWizard1.UserName);

    //Construct the verification URL
    string VerifyUrl = Request.Url.GetLeftPart(UriPartial.Authority) + Page.ResolveUrl("~/Verify.aspx?ID=" + userInfo.ProviderUserKey.ToString());

   // Replace <%VerifyUrl%> placeholder with verifyUrl value
    e.Message.Body = e.Message.Body.Replace("VerifyUrl", VerifyUrl.ToString());
}

This is the html file that what user would see in their email:
