Send Activation Email after Create User Account

Try these three ways to send email to user to active his account to be able to login to website

————–First Way ————-
    protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
    {
        //Send email to user for verifying account
        CreateUserWizard cuw = (CreateUserWizard)sender;
        MembershipUser user = Membership.GetUser(cuw.UserName);
        Guid userId = (Guid)user.ProviderUserKey;
        System.Net.Mail.MailMessage EmailMsg = new System.Net.Mail.MailMessage("info@ask.com", CreateUserWizard1.Email);
        EmailMsg.Subject = "Email Verification from ask.com";
        EmailMsg.IsBodyHtml = true;
        EmailMsg.Body = "Thanks for registering with www.ask.com!<br /><br />Your activation link : <a href=http://www.ask.com/activate.aspx?ID=" + userId.ToString() + ">Link</a>.";
        System.Net.Mail.SmtpClient mailClient = new System.Net.Mail.SmtpClient();
        //This object stores the authentication values
        System.Net.NetworkCredential basicAuthenticationInfo = new System.Net.NetworkCredential("smtpserverinfo", "smtpserverpassword");

        mailClient.Host = "mail.ask.com";
        mailClient.UseDefaultCredentials = false;
        mailClient.Credentials = basicAuthenticationInfo;
        mailClient.Send(EmailMsg);    

    }

and in activate.aspx:

    protected void Page_Load(object sender, EventArgs e)
    {
        Guid oGuid = new Guid(Request.QueryString["ID"]);
        //Guid oGuid = new Guid();
        MembershipUser oUser = Membership.GetUser(oGuid);
        if (oUser != null && oUser.IsApproved == false)
        {
            oUser.IsApproved = true;
            Membership.UpdateUser(oUser);
            System.Web.Security.FormsAuthentication.RedirectFromLoginPage(oUser.UserName, false);
        }
    }

———Second Way———–

My code looks like:

    protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
    {
        //Send email to user for verifying account
        CreateUserWizard cuw = (CreateUserWizard)sender;
        MembershipUser user = Membership.GetUser(cuw.UserName);
        Guid userId = (Guid)user.ProviderUserKey;
        System.Net.Mail.MailMessage EmailMsg = new System.Net.Mail.MailMessage("info@ask.com", CreateUserWizard1.Email);
        EmailMsg.Subject = "Email Verification from ask.com";
        EmailMsg.IsBodyHtml = true;
        EmailMsg.Body = "Thanks for registering with www.ask.com!<br /><br />Your activation link : <a href=http://www.ask.com/activate.aspx?ID=" + userId.ToString() + ">Link</a>.";
        System.Net.Mail.SmtpClient mailClient = new System.Net.Mail.SmtpClient();
        //This object stores the authentication values
        System.Net.NetworkCredential basicAuthenticationInfo = new System.Net.NetworkCredential("info@ask.com", "password"); //what is this "password" for??

        mailClient.Host = "mail.ask.com";
        mailClient.UseDefaultCredentials = false;
        mailClient.Credentials = basicAuthenticationInfo;
        mailClient.Send(EmailMsg);      

    }

and in activate.aspx:

     protected void Page_Load(object sender, EventArgs e)
    {
        Guid oGuid = new Guid();
        MembershipUser oUser = Membership.GetUser(oGuid);
        if (oUser != null && oUser.IsApproved == false)
        {
            oUser.IsApproved = true;
            Membership.UpdateUser(oUser);
            System.Web.Security.FormsAuthentication.RedirectFromLoginPage(oUser.UserName, false);
        }
    }
