我在 Visual Studio 2010 中遇到了这个发送邮件脚本的挑战。

这是脚本：

         * To use a parameter in this script, follow the same steps. Parameters are always read-only.

这是我得到的错误：

SSIS 包“C:\Users\xxx\xxxx\visual studio 2010\projects\xxxx\xxxx\xxx.dtsx”正在启动。 错误：脚本任务中的 0xFFFFFFFF，ST_dd466aa1cac943eb887bc0d48f753e68：System.Net.Mail.SmtpException：操作已超时。 在 System.Net.Mail.SmtpClient.Send（MailMessage 消息） 在 ST_dd466aa1cac943eb887bc0d48f753e68.ScriptMain.SendMail（字符串 sSubject，字符串 sMessage，Int32 iPriority） 错误：脚本任务中的 0x6：脚本返回失败结果。 任务失败：脚本任务

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

其次，我也想将附件作为变量。

在此期间，我使用的是 godaddy 电子邮件、Windows Server 2012R2 和 Visual Studio 2010。

【问题讨论】：

您正在发送邮件，它正在超时，因此服务器可能无法访问或 GoDaddy 服务器的响应延迟导致超时

感谢 Brad，但我已通过服务器的管理工具授予访问权限 - 我需要授予其他访问权限还是需要授予什么访问权限？干杯

不清楚，抱歉，访问意味着计算机可以访问 GoDaddy 服务器（由于防火墙、对服务器的限制，以及其他类似的东西）。它是否在您的机器上本地运行？

这里是服务器上的防火墙设置：在域、私人和公共配置文件中都允许入站和出站连接。我将尝试在我的 Mac 上运行它，看看它是否运行。再次感谢

【参考方案1】：

对于您的附件，您可以这样做，其中 EmailAttachmentPaths 是一个以逗号分隔的路径

// 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
