比较-对象与参考对象排序

Question

我有两个文件（用于 CNC 控制器）想要比较。我可以通过比较对象得到很好的结果：

$Diffs = Compare-Object -ReferenceObject $CFFC -DifferenceObject $CSFC -IncludeEqual

我遇到的问题是我想以与参考对象相同的文件顺序打印结果；更改内容和原始内容的摘要。比较对象结果按 SideIndicator 排序，这使得很难准确比较文件已更改的位置。

我可以通过 foreach 循环并创建一个新变量来完成此操作，但这需要非常长的时间。

$NewArr=@()
foreach($line in $csfc){
    $ChangeStatus = ($Diffs -match [regex]::Escape($line)).SideIndicator
    $LineStatus = "" | Select LINE, TYPE
    if ($ChangeStatus -eq "=="){
        $LineStatus.line = $line
        $LineStatus.Type = $true
        }
    else{
        $LineStatus.line = $line
        $LineStatus.Type = $false
        }

    $newarr += $LineStatus
}

我想知道是否有更快、更稳健的方法来做到这一点

编辑 1：例如，如果某行在输入文件中重复 3 次，而在引用中仅重复两次，我如何发现第 3 行是新行？

Answer 1

看来您真正要寻找的是两个集合按索引的对称差异，在这种情况下您可以只使用

for

循环。假设我们将 2 个集合存储在

$referenceObject

和

$differenceObject

中，您的逻辑可能是：

for ($i = 0; $i -lt $referenceObject.Count; $i++) {
    [pscustomobject]@{
        Line    = $referenceObject[$i]
        Changed = $referenceObject[$i] -ne $differenceObject[$i]
    }
}

给定样本数据，将输出：

Line                                   Changed
