ASP.NET2.0郵件群發

首先添加命名空間using System.Net.Mail;using System.Data.SqlClient;代碼其實很簡單，當然我這個功能比較簡單就是一個單擊事件

 

protected void btn_send_Click(object sender, EventArgs e)
    ...{
         MailMessage message = new MailMessage();
        //擷取寄件者地址
         message.From = new MailAddress(tbx_address.Text.Trim());
        //擷取主題
         message.Subject = tbx_subject.Text.Trim();
        //擷取發送郵件主題
         message.Body = we_content.Text.Trim();
         message.IsBodyHtml = true;
        //設定資料庫連結
         SqlConnection conn = new SqlConnection(getstring());
         conn.Open();
        //資料查詢用的是預存程序
         SqlCommand cmd = new SqlCommand("SelectEmail", conn);
         cmd.CommandType = CommandType.StoredProcedure;
         SqlParameter dutyparameter = cmd.Parameters.Add("@MemberDuty", SqlDbType.NVarChar, 20);
         dutyparameter.Value = ddl_selectemail.SelectedValue;
         SqlDataReader dr = cmd.ExecuteReader();
        //執行查詢獲得要發往的郵件地址
        while (dr.Read())
        ...{
             message.To.Add(dr["MemberEmail"].ToString());
           
         }
         conn.Close();
         SmtpClient client = new SmtpClient();
         client.Send(message);
         lbl_info.Visible = true;
         lbl_info.Text = "發送成功";
       
     }

另外在web。config設定發送郵件的遠程伺服器串連

代碼如下

<system.net>
  <mailSettings>
    <smtp>
      <network host="smtp.163.com" port="25" userName="你的163帳號" password="你的密碼" />
      </smtp>
    </mailSettings>
  </system.net>
