我想运行powershell命令，获取当前windows服务的信息。
例如Redis：
当前路径为：“C：\Program Files\Redis\redis-server.exe”

Get-WmiObject win32_service |?{$_.Name -like 'redis*'} | Select-Object Name, DisplayName, state, startmode, @{Name="Path"; Expression={$_.PathName.split('"')}}| convertto-json

{
    "Name":  "Redis",
    "DisplayName":  "Redis",
    "state":  "Running",
    "startmode":  "Auto",
    "Path":  "C:\\Program Files\\Redis\\redis-server.exe"
}

但我想用这条路：“C：\Program Files\Redis”

Get-WmiObject win32_service |?{$_.Name -like 'redis*'} | Select-Object Name, DisplayName, state, startmode, @{Name="Path"; Expression={$_.PathName.split('"')[1].split('\\')[0..3]}}| convertto-json

{
    "Name":  "Redis",
    "DisplayName":  "Redis",
    "state":  "Running",
    "startmode":  "Auto",
    "Path":  {
                 "value":  [
                               "C:",
                               "Program Files",
                               "Redis",
                               "redis-server.exe"
                           ],
                 "Count":  4
             }
}

有没有办法像这样指挥

...split('\\')[0..length-1]}}
