【问题描述】：

电子邮件不会发送。我需要某种 Try /Catch 循环吗？在 Powershell 中检查错误的最佳方法是什么？

我需要它来检查每个位置，如果没有找到一个位置，它仍然会发送其他位置并显示一条消息，说明哪些报告已发送，哪些不取决于是否在文件夹中找到报告

Send-MailMessage：无法验证参数“主题”的参数。参数为 null 或空。提供一个不为 null 或空的参数，然后再次尝试该命令。

   #Defines Directory
   $dir = "C:\Users\user\Desktop\reprts\Todays"
   #Sets STMP server
   $SMTPServer = "10.0.0.46"
   #Declares todays time and formats
   $Time = (Get-Date).ToString('MM/dd/yyyy hh:mm tt')

   $japan = @{            
       Name = 'japan'
       From = "me@me.com"
       To = "you@you.com"
       Cc = "him@him.com"
   }

   $ireland = @{

       From = "me@me.com"
       To = "you@you.com"

【问题讨论】：

您报告的错误消息告诉您问题所在。您需要进行一些调试；您是否尝试检查导致分配给$Subject 的过程的每个步骤的相关值？
我会猜测（我必须这样做，因为它们不是显示您对 Send-MailMessage 的调用的代码）您没有添加主题，或者如果您有它是空的。该错误对于问题是绝对正确的。在您显示的代码中没有$subject
你已经问了两次这个问题，你的第一个更好。如果您仍有问题，请使用相关信息编辑第一个问题。您可以在那里 ping 答案的作者，看看他们是否可以再次帮助您。请避免转发问题。

【解决方案1】：

我添加了一些错误处理。

如果发送成功与否，将返回区域对象，但会返回一条消息，说明失败的位置/原因
