我如何通过asp.net从本地主机发送带有附件文件的邮件?

问题描述

我的代码是:

My code is:

protected void Button1_Click(object sender, EventArgs e)
     {
         //string path = "D:\\Test.txt";
         try
         {
             //FileStream file = null;

             // //Read the file. This appears to be the offending line
             //file = File.OpenRead(path);
             //byte[] Content = new byte[file.Length];
             //file.Read(Content, 0, (int)file.Length);
             //file.Close();
             //file.Dispose();
             //Label1.Text = Content.ToString();

             MailMessage mail = new MailMessage();
             //m.ail.To.Add("[email protected]");
             mail.To.Add("[email protected]");
             mail.To.Add("[email protected]");
             //mail.To.Add("[email protected]");
             mail.From = new MailAddress("[email protected]");
             mail.Subject = "Send Email by asp.net code using google or gmail smtp server";

             string Body = "Hi, I am testing Email function in asp.net" +
                           " using google or gmail smtp server"+
                           " and next time I will send you a document from my .aspx file";
             mail.Body = Body;
             Attachment at = new Attachment("D:\\Text.txt");
             mail.Attachments.Add(at);

             mail.IsBodyHtml = true;

             SmtpClient smtp = new SmtpClient("localhost",25);
             smtp.Host = "smtp.gmail.com"; //Or Your SMTP Server Address
             smtp.Credentials = new System.Net.NetworkCredential
                  ("[email protected]", "abcdef");
             //Or your Smtp Email ID and Password
             smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
             smtp.EnableSsl = true;

             smtp.Send(mail);
             Label1.Text = "Mail Send...";
         }
         catch (Exception ex)
         {
             Label1.Text = ex.Message;
         }
     }

比我得到错误消息:


Web.Config文件中有什么问题吗?请向我发送一个web.config文件设置以解决此问题?

Than I got the error message:


Is there any problem in Web.Config file ? Please send me a web.config file setting for solve this problem?

推荐答案

<system.net>
  <mailSettings>
      <smtp deliveryMethod="PickupDirectoryFromIis">
          <network defaultCredentials="true" host="localhost" port="25"/>
      </smtp>
  </mailSettings>
</system.net>

并将其添加到您的代码中:

and add this to your code:

smtp.DeliveryMethod = SmtpDeliveryMethod.Network;

<system.net>
    <mailsettings>
      <smtp deliverymethod="PickupDirectoryFromIis" />
    </mailsettings>
  </system.net>

它是主线:-

it is the main line:-

<smtp deliverymethod="PickupDirectoryFromIis" />
