Question

即使我使用$ workflow前缀限定它，我也无法在子范围内访问工作流变量：

workflow Test-3 {
      $services = "w32time", "spooler"
      $name = "Workflow Test"
      write-verbose -Message ("Local count is {0}" -f $services.Count)
     parallel {
       write-verbose -Message "Name in parallel clause is $workflow:name"
       sequence {
         $seqServices = Get-Service -Name $workflow:services
         write-verbose -Message ("Seq count is {0}" -f $seqServices.Count)
       }
     }

}

这就是我在输出中看到的：

VERBOSE：[localhost]：本地计数为2

VERBOSE：[localhost]：并行子句中的名称是

VERBOSE：[localhost]：Seq计数为165

感谢是否有人可以指出输出中的偏差。

好吧，我似乎无法在序列块中传递集合。我通过创建本地集合来实现它。枚举父集合（$ workflow：var）有效..

sequence {
$seqServices = @()
foreach($s in $workflow:services){$seqServices += $s}
#This works now
$psServices = Get-Service -Name $seqServices
write-Verbose -Message ("Sequence count is {0}" -f $psServices.Count)

}

我现在看到了..

VERBOSE：[localhost]：序列计数为2
