Question

我有脚本，它有效，而且可能有一些愚蠢的标志丢失，但我无法找到它。请帮帮我？应该弹出一个选择栏并根据所选项目更改$答案。

#What project do you work on
$caption = "Choose Action";
$message = "What project are you testing?";
$LLL = new-Object System.Management.Automation.Host.ChoiceDescription "&LLL","LLL";
$JJJ = new-Object System.Management.Automation.Host.ChoiceDescription "&JJJ","JJJ";
$PPP = new-Object System.Management.Automation.Host.ChoiceDescription "&PPP","PPP";
$choices = [System.Management.Automation.Host.ChoiceDescription[]]($LLL,$JJJ,$PPP);
$Project = $host.ui.PromptForChoice($caption,$message,$choices,0)

switch ($Project) {
    0 {"LLL"; break}
    1 {"JJJ"; break}
    2 {"PPP"; break}
    }


if ($Project -eq 0) 
    {
    $Answer = "LLL" 
    }


if ($Project -eq 1) 
    {
    $Answer = "JJJ" 
    }


if ($Project -eq 2) 
    {
    $Answer = "PPP" 
    }


the error is that 

o.ps1:128 char:23
+     if ($Project -eq 1)
+                       ~
Missing statement block after if ( condition ).

您的代码应该有效。如果您只想设置$Answer，也可以在切换块中执行此操作：

$Answer = switch ($Project) {
    0 {'LLL'}
    1 {'JJJ'}
    2 {'PPP'}
}

现在你可以省略所有if语句......
