Powershell Topshelf卸载继续锁定文件

Question

使用以下topshelf uninstall命令：

& $path uninstall -servicename:"MyService" -displayname "MyService"

该命令似乎继续运行，因为它包含在powershell脚本的生命周期中并锁定文件，因此我无法覆盖它们。有没有办法确保它的作用终止，所以我的脚本可以不受阻碍地进行？

Answer 1

卸载Windows服务的另一种方法。可以用作script module。

function Uninstall-WindowsService($serviceName)
{
    $existingService = (Get-WmiObject Win32_Service -filter "name='$serviceName'")
    if ($existingService) 
    {
      Write-Host "Stopping the '$serviceName'."
      Stop-Service $serviceName
      Write-Host "Waiting 3 seconds to allow existing service to stop."
      Start-Sleep -s 3

      $existingService.Delete()
      Write-Host "Waiting 15 seconds to allow service to be uninstalled."
      Start-Sleep -s 15
    }
}

Answer 2

If (Get-Service $serviceName -ErrorAction SilentlyContinue) {
    $servicePath = (Get-WmiObject win32_service | ?{$_.Name -like $serviceName} | Select-Object Name, @{Name="Path"; Expression={$_.PathName.split('"')[1]}}).Path
    Write-Host "Uninstalling service from $servicePath"
    Invoke-Expression "$servicePath uninstall"}
