        Response.Write(ex.ToString());
    }

これらのコード行により、mail使用中のsmtpポートを送信できるようになり、正常に動作します。他の見込み客を見ると、のようなexceptions入力の可能性がある場所があるかもしれませんし、特定の時間にメールを送信できない場所があるかもしれませんし、他の例外があるかもしれません。ポップアップウィンドウが表示されるか、メールが送信できないなどのエラーメッセージが表示されるはずですが、可能性はありますか?Dummy emailabc@gmail.comserver issues

<asp:Label>オーバー/アンダーを追加するだけGridViewで、例外が発生した場合はTextエラーメッセージに設定できます。

<asp:Label ID="lblMsg" runat="server"></asp:Label>

..

try{
    sendMail(toemail);
}
catch(Exception ex){
    lblMsg.Text = ex.Message; // or whatever message you want to show
    lblMsg.ForeColor = Color.Red // Red shows error
}

...

public void sendMail(String toemail){

    try{
        ...
    }
    catch(Exception ex){
        throw ex; // Don't use Response.Write
    }
}
