Question

我是PowerShell的新手，提前道歉。我从这里找到的脚本开始：Getting Event Log contents by email（非常值得信赖和感谢）并将其调整为我需要它工作的方式。基本上，当这个错误代码发生时，它每60秒发布一次，因此我只需要经常发送一封电子邮件，最近20个事件在基本表中转换为HTML。在ISE中执行脚本时，一切都很有效，但是在常规PowerShell控制台中运行时或作为计划任务时不会发送电子邮件。有一点需要注意，我可以将所有内容运行到PowerShell控制台中的电子邮件部分，并将其写入HTML文件EventID-To-HTML | Out-File -FilePath $filePath -Append。作为新人，我确信我没有完全正确处理事情，所以反馈总是受到赞赏。非常感谢

我怀疑问题是$ eventstring的范围问题。它是在EventID-To-HTML功能中创建的。由于在ISE中使用作用域的方式，该函数在函数运行后仍然可用。通常，函数在其自己的作用域中运行，并且当它存在时，作用域被处理掉并且它将使用该作用域中创建的所有变量。

您可以通过点源函数对其进行测试，使其在当前范围内运行。

. EventID-To-HTML | Out-File -FilePath $filePath -Append

注意点和函数名称之间的空格。必须在那里。

避免这种情况的一种方法是使用类似数组的集合类型而不是aray。

$eventstring = new-object collections.arraylist
    Foreach ($i in $Event) {
        $eventstring.add("$($i.Message), $($i.TimeGenerated)") > $nul

PowerShell脚本不会在ISE之外运行
