轉貼:[ASP.net] 完整的Mail寄信功能 懶人Code分享

看到這個寫好的程式,讓我想了五分鐘,到底該不該拿過來用呢??最後決定還是copy過來用,因為真的太贊了。

public bool Mail_Send(string MailFrom, string[] MailTos,string[] Ccs, string MailSub, string MailBody, bool isBodyHtml,string[] filePaths)
{

   

    try
    {
        //防呆
        if (MailFrom == "")
        {
            MailFrom = "sysadmin@system.com.tw";
        }

        //命名空間: System.Web.Mail已過時,http://msdn.microsoft.com/zh-tw/library/system.web.mail.mailmessage(v=vs.80).aspx
        //建立MailMessage物件
        System.Net.Mail.MailMessage mms = new System.Net.Mail.MailMessage();
        //指定一位寄信人MailAddress
        mms.From = new MailAddress(MailFrom);
        //信件主旨
        mms.Subject = MailSub;
        //信件內容
        mms.Body = MailBody;
        //信件內容 是否採用Html格式
        mms.IsBodyHtml = isBodyHtml;

        if (MailTos !=null)//防呆
        {
            for (int i = 0; i < MailTos.Length; i++)
            {
                //加入信件的收信人(們)address
                if (!string.IsNullOrEmpty(MailTos[i].Trim()))
                {
                    mms.To.Add(new MailAddress(MailTos[i].Trim()));
                }
               
            }
        }//End if (MailTos !=null)//防呆

        if (Ccs!=null) //防呆
        {
            for (int i = 0; i < Ccs.Length; i++)
            {
                if (!string.IsNullOrEmpty(Ccs[i].Trim()))
                {
                    //加入信件的副本(們)address
                    mms.CC.Add(new MailAddress(Ccs[i].Trim()));
                }
              
            }
        }//End if (Ccs!=null) //防呆

        if (filePaths!=null)//防呆
        {//有夾帶檔案
            for (int i = 0; i < filePaths.Length; i++)
            {
                if (!string.IsNullOrEmpty(filePaths[i].Trim()))
                {
                    Attachment file = new Attachment(filePaths[i].Trim());
                    //加入信件的夾帶檔案
                    mms.Attachments.Add(file);
                }
              
            }
          
        }//End if (filePaths!=null)//防呆
     
        SmtpClient client = new SmtpClient("msa.hinet.net");//或公司、客戶的smtp_server
        //以下可以省略,因為寄信不用帳密(除非客戶特別要求)
        client.Credentials = new System.Net.NetworkCredential(WebConfigurationManager.AppSettings["SMTPsendusername"],
                                                                                          WebConfigurationManager.AppSettings["SMTPsendpassword"]);

        client.Send(mms);//寄出一封信
        return true;//成功
      }
      catch
      {
        return false;
      }
}

使用方法:

//寄信人E-mail
string From_mail = "from_mail@hotmail.com";
//收信人E-mail
string[] to_emails = new string[] { @"to_email@hotmail.com", @"to_email2@hotmail.com" };
//副本
string[] to_cc = new string[] { @"to_email@hotmail.com", @"to_email2@hotmail.com" };
//主旨
string Subject = "我是主旨";
//內文
string htmlBody = TextBox1.Text.Trim().Replace(Environment.NewLine, "<br />");
//附檔在WebServer上的路徑
string[] filePaths = new string[] { @"D:\web\upload\xxx.xls", @"D:\web\upload\test.txt" };

//寄信
bool sendResult = Mail_Send(From_mail, to_emails, to_cc, Subject, htmlBody, true, filePaths);
