使用System.Net.Mail時沒有驗證功能

Question

看來，當我在後臺代碼中爲聯繫頁面配置電子郵件設置時，驗證控件不再有效。我需要字段驗證和正則表達式驗證來驗證電子郵件地址。在插入需要我使用System.Net.Mail的電子郵件配置之前，驗證適用於點擊事件。這是後面的代碼：

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; 
} 
}

你忘了在Button1_Click開始檢查Page.IsValid。
