正在尝试编写执行以下操作的PowerShell脚本：

寻找服务存在

如果找到，请检查服务状态

报告服务状态

如果服务状态未运行，则启动服务

报告服务状态

仔细看看你一开始做了什么：

$arrService = Get-Service -Name $ServiceName

$arrService.Status

现在反映了开始执行任何操作之前服务的状态-让我们想象一下，该状态是
已停止

然后，在脚本的后面：

if ($arrService.Status -ne "Running"){
    Start-Service $ServiceName | Out-File $LogFile -append
}

if ($arrService.Status -eq "Running"){
       Write-Output "$date - '$ServiceName' started..." | Out-File $LogFile -append
       Write-Output " " | Out-File $LogFile -append
       FinalServiceStatus
}
else{
    Write-Output "Error: '$ServiceName' service could not be started..." | Out-File $LogFile -append
    Write-Output " " | Out-File $LogFile -append
    FinalServiceStatus
}

这部分工作与预期的一样-启动脚本时服务没有运行，所以现在就可以启动了，太棒了

然后是脚本中有问题的部分：

if ($arrService.Status -ne "Running"){
    Start-Service $ServiceName | Out-File $LogFile -append
}

if ($arrService.Status -eq "Running"){
       Write-Output "$date - '$ServiceName' started..." | Out-File $LogFile -append
       Write-Output " " | Out-File $LogFile -append
       FinalServiceStatus
}
else{
    Write-Output "Error: '$ServiceName' service could not be started..." | Out-File $LogFile -append
    Write-Output " " | Out-File $LogFile -append
    FinalServiceStatus
}

由于

$arrService.Status

仍然具有与以前完全相同的值（即使服务本身现在可能已将其状态更改为

Running

），因此执行

else

块，无论服务是否已成功启动

您需要再次调用

Get Service

来获取服务的新值，或者（我个人最喜欢的）使用

Start Service-PassThru

来“更新”

$arrService

变量：

if($arrService.Status -ne 'Running')
{
    $arrService = Start-Service $ServiceName -PassThru
}

if($arrService.Status -eq 'Running')
{
    "Service is running" # although we don't know whether it was just started or already had been 
}
else
{
    "Service not running, starting must have failed"
}

对于任何感兴趣的人，根据Mathias的建议，以下是我的代码最终的样子（就逻辑而言）：

$arrService.Status

不会在不同的if/else语句之间更改，它在整个脚本中保持不变。再次运行

Get Service

而不是检查，并且“旧”变量值

$arrService.Status

不会在不同的if/else语句之间更改，它在整个脚本中保持不变。再次运行

Get Service

，而不是检查和“旧”变量值谢谢您，@Mathias。我在你的帮助下成功了。完全忽略了这一点，但绝对理解这可能是一个问题。-passthru开关的触感也很好：）。现在，如果我能得到正确的格式…这是一个不同的问题（请随意问一个新的）。提示：不要使用

格式列表

，它会添加不需要的换行符。明白了。谢谢你在解决最大问题上的帮助@Mathias。谢谢你，Mathias。我在你的帮助下成功了。完全忽略了这一点，但绝对理解这可能是一个问题。-passthru开关的触感也很好：）。现在，如果我能得到正确的格式…这是一个不同的问题（请随意问一个新的）。提示：不要使用
