Question

这可能是一个简单的错误，我的脚本重新启动服务器并通过电子邮件发送预启动时间和启动后时间。现在重新启动工作和电子邮件工作但电子邮件中的时间是空白的，现在如果我键入write-host $ sgr11我得到的时间就好了。然而，在某个地方，它没有进入我的电子邮件正文...任何信息都会很棒，我知道我的代码非常混乱，根本没有效率。我只做了大约一个星期，任何有建设性的事情，你想指出帮助会很棒。

结果电子邮件就是这样的。我注意到的一件事是，每次我在ISE中运行脚本时，每次都需要更长的时间，不确定这是否相关。

基本上，您的问题是您在创建字符串中的变量之前创建了电子邮件正文字符串，因此它们会扩展为null。在不重新安排代码的情况下解决这个问题的简单方法是将here-string放入脚本块，然后在创建变量后调用脚本块并准备好使用字符串：

$start = $null
$end = $null

$body_string  = @"
Start time is $start
End time is $end
"@

$body_scriptblock = {@"
Start time is $start
End time is $end
"@}

$start = get-date
start-sleep -Seconds 2
$end = get-date

$body_string

&$body_scriptblock


Start time is 
End time is 
Start time is 07/10/2014 20:27:00
End time is 07/10/2014 20:27:02

在电子邮件设置中调用Var时，数据会丢失。 - 电源外壳
