c# - 使用 System.Net.Mail 时没有验证功能

Question

似乎当我在联系页面后面的代码中配置我的电子邮件设置时，验证控件不再起作用。我需要字段验证和正则表达式验证来验证电子邮件地址。在我插入要求我使用 System.Net.Mail 的电子邮件配置之前，验证适用于点击事件。这是后面的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Mail;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Contact : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void Button1_Click(object sender, EventArgs e)
{
    MailMessage mail = new MailMessage();
    mail.To.Add("email@gmail.com");
    mail.From = new MailAddress(EmailAddressTextBox.Text);
    mail.Subject = SubjectTextBox.Text;

    mail.Body = "email address: " + EmailAddressTextBox.Text + "<br />" + MessageTextBox.Text;

    mail.IsBodyHtml = true;
    SmtpClient smtp = new SmtpClient();
    smtp.Host = "smtp.gmail.com"; //Or Your SMTP Server Address  
    smtp.Credentials = new System.Net.NetworkCredential
         ("email@gmail.com", "password");
    //Or your Smtp Email ID and Password  
    smtp.EnableSsl = true;
    smtp.Port = 587;
    smtp.Send(mail);

    EmailAddressTextBox.Text = String.Empty;
    SubjectTextBox.Text = String.Empty;
    MessageTextBox.Text = String.Empty;
}
}

您忘记Page.IsValid在Button1_Click.
