无法使用脚本任务从 SSIS 发送邮件 - 超时

Question

我使用循环创建了 SSIS 包。此包从 Reporting Services 导出 2 个文件（一个 pdf，一个 xlsx）。

通常，在通过 Outlook 发送导出文件的“脚本任务”中会出现超时错误。我看了但我想不通，我不是关于 c# 的出口。

错误描述。 ; System.Net.Mail.SmtpException：操作已超时。在 System.Net.Mail.SmtpClient.Send(MailMessage) .......

我的代码；

这可能是因为您的文件的大小。如果它们超过 600 mb 我猜，你会得到错误。首先检查文件的大小。
