停止 PowerShell 脚本或重新询问 Right-Host 的最佳方法

Question

这是我的代码。感觉真的很脏，我有一长串我要问的 Right-Host 问题。

如果添加了 Null、空白或其他空条目（包括仅添加 space），我想停止脚本。现在我已经让它停止了，但希望有一种更简洁的方法来对 "If" 语句进行分组，并且如果上述任何条目发生，也许会重新提出问题...

$Parent = Read-Host -prompt "Enter full parent path that will contain the new folder"
if ( $Parent -eq $null)
  {
    Write-Host "You entered a blank value: This Script is now Exiting."
    Exit
  }
if ( $Parent -eq "")
  {
    Write-Host "You entered a blank value: This Script is now Exiting."
    Exit
  }
if ( $Parent -eq " ")
  {
    Write-Host "You entered a blank value: This Script is now Exiting."
    Exit
  }
else 
  {
    Write-Host "You Entered $Parent"
  }

$Name = Read-Host -prompt "Enter Folder Name"
if ( $Name -eq $null)
  {
    Write-Host "You entered a blank value: This Script is now Exiting."
    Exit
  }
if ( $Name -eq "")
  {
    Write-Host "You entered a blank value: This Script is now Exiting."
    Exit
  }
if ( $Name -eq " ")
  {
    Write-Host "You entered a blank value: This Script is now Exiting."
    Exit
  }
else 
  {
    Write-Host "You Entered $Name"
  }

Answer 1

您可以像这样将验证条件放在一起：

$Parent = Read-Host -prompt "Enter full parent path that will contain the new folder"

 if ( ($Parent -eq $null) -or ($Parent -eq "") -or ($Parent -eq " "))
  {
Write-Host "You entered a blank value: This Script is now Exiting."
  }
else 
  {
Write-Host "You Entered $Parent"
  }

您可以使该函数成为一个带有强制性非空参数的函数（正如 bill 在长运行上所说的很多 better/easier），或者进行 while 循环直到输入正确。
