使用Visual Studio 2010的SSIS發送郵件任務腳本

我在Visual Studio 2010中使用此發送郵件腳本遇到了挑戰。

這是腳本：

這是我得到的錯誤：

SSIS包“ C：\\ Users \\ xxx \\ xxxx \\ visual studio 2010 \\ projects \\ xxxx \\ xxxx \\ xxx.dtsx”開始。 錯誤：腳本任務ST_dd466aa1cac943eb887bc0d48f753e68處的錯誤為0xFFFFFFFF：System.Net.Mail.SmtpException：操作已超時。 在ST_dd466aa1cac943eb887bc0d48f753e68.ScriptMain.SendMail（String sSubject，String sMessage，Int32 iPriority）的System.Net.Mail.SmtpClient.Send（MailMessage消息）處出現錯誤：腳本任務處錯誤：0x6：腳本返回了失敗結果。 任務失敗：腳本任務

SSIS軟件包“ C：\\ Users \\ xxx \\ xxxx \\ visual studio 2010 \\ projects \\ xxxx \\ xxxx \\ xxx.dtsx”已完成：成功。

其次，我也希望將附件作為變量。

之間，我正在使用Godaddy電子郵件，Windows Server 2012R2和Visual Studio 2010。

對於您的附件，您可以執行以下操作，其中EmailAttachmentPaths是帶有逗號分隔路徑的字符串

// this is to add multipel attachments ","
            string[] ToMuliPaths = EmailAttachmentPaths.Split(',');
            foreach (string ToPathId in ToMuliPaths)
            {
                // only add email if not blank
                if (ToPathId.Trim() != "")
                    mailMessage.Attachments.Add(new Attachment(ToPathId));
            }// end for loop
