从C＃调用内部具有后台作业的Powershell脚本

[英]Powershell script with a background job inside called from c#

原文 2013-02-14 07:17:01 4 1 c#/ powershell/ asynchronous

I call a Powershell script from a c# program, getting back an collection of PSObjects as a result of pipeline.Invoke() . 我从c#程序中调用Powershell脚本，由于pipeline.Invoke()的结果而返回了PSObjects的集合。 As a part of the PS script, an email is sent using Net.Mail.SmtpClient. 作为PS脚本的一部分，使用Net.Mail.SmtpClient发送电子邮件。 However, sending an email takes some time, so I moved the email sending code into a script block that is executed using Start-Jon -ScriptBlock ... And here the problem started: email is not sent. 但是，发送电子邮件需要花费一些时间，因此我将电子邮件发送代码移到了一个脚本块中，该脚本块使用Start-Jon -ScriptBlock执行...在这里，问题开始了：未发送电子邮件。 When I execute a script from a command line, it sends an email. 当我从命令行执行脚本时，它将发送电子邮件。

What can be the reason? 可能是什么原因？

Actually, after adding Wait-Job to the code (making it synchronous) it worked again. 实际上，在将Wait-Job添加到代码（使其同步）之后，它又可以工作了。 I think that I got it. 我想我明白了。 I was calling runspace.Close() at the end of my code that terminated the host so the Powershell background job had no chance to be executed. 我在终止主机的代码结尾处调用runspace.Close() ，因此Powershell后台作业没有机会执行。 So I looking in the wrong place, unfortunately. 因此，很不幸，我在错误的位置看。
