这个powershell脚本有什么问题？

Question

如此努力，我无法弄清楚它有什么问题。它可能会变得微不足道，令人尴尬，我放弃了

Param(
[string]$i = "",
 [int]$start,
 [int]$end,
 [int]$width,
 [int]$height,
 [string]$o = ""
)

if ($i.Length == 0 or $o.Length == 0 or ($width == 0 and $height == 0)) 
{
    Write-Host "input, output, either of width of height are required"
    Exit
}
$sum = $start + $end
if ( not ($sum==0) and ($sum == $start or $sum == $end))
{
    Write-Host "When either of the start or end is supplied, the other has to be supplied too"
    Exit
}

 $widthString = $width.ToString()
 $heightString = $width.ToString()

if (($width -ge 0) and $height==0) 
{
}

您已将此标记为PowerShell，因此我认为这是您尝试撰写的语言？

您的令牌在PowerShell中无效，可以找到一个比较好的逻辑运算符列表here。

简而言之，==应为-eq，and应为-and，or应为-or，依此类推。< / p>
