我查看了许多示例，并在制作变更报告方面取得了进展。但是，我被困在一个领域。这是场景...

File 1 CSV file sample data
ID,Name,Location,Gender
1,Peter,USA,Male
2,Paul,UK,Male
3,Mary,PI,Female

File 2 CSV file sample data (No ID column)
Name,Location,Gender
Peter,USA,Female
Paul,UK,Male
Mary,USA,Female
Tom,PI,Female
Barry,CAN,Male

档案2有变化和补充，即彼得变成了女性，玛丽搬到了美国，汤姆和巴里都是新人。更改报告输出文件包含更改内容。问题是，我不知道如何将文件 1 中的 Peter 和 Mary 的 ID 放入我的变更报告中。ID 总是空的这是我的代码......（我希望有人能解释一下。在此先感谢。）

$MyCSVFields = @('Name','Location','Gender')
$CompareResults = Compare-Object $RefObj $DffObj -Property $MyCSVFields -IncludeEqual
$NewOrChangedData = @()
Foreach($Row in $CompareResults)
{
    if( $Row.SideIndicator -eq "=>" )
    {                
        $TempObject = [pscustomobject][ordered] @{
            ID = $Row.ID
            Name = $Row.Name
            Location = $Row.Location
            Gender = $Row.Gender
            #Sanity check "Compare Indicator" = $Row.SideIndicator 
        }
        $NewOrChangedData += $TempObject
    }
}

感谢 Theo 提供了对如何使用 Where-Object 的理解。这是更新后的代码，它对初学者来说很简单，并且仍然适用于我们。

Foreach($Row in $CompareResults)
{
    if( $Row.SideIndicator -eq "=>" )
    {                
        $myOrgID = $RefObj | Where-Object Name -eq $Row.Name
        $TempObject = [pscustomobject][ordered] @{
            ID = $myOrgID.ID
            Name = $Row.Name
            Location = $Row.Location
            Gender = $Row.Gender
            #Sanity check "Compare Indicator" = $Row.SideIndicator 
        }
        $NewOrChangedData += $TempObject
    }
}

我也一直在苦苦挣扎Compare-Object，所以我希望有比这更好的答案：

$RefObj = @'
ID,Name,Location,Gender
1,Peter,USA,Male
2,Paul,UK,Male
3,Mary,PI,Female
'@ | ConvertFrom-Csv

$DffObj = @'
Name,Location,Gender
Peter,USA,Female
Paul,UK,Male
Mary,USA,Female
Tom,PI,Female
Barry,CAN,Male
'@ | ConvertFrom-Csv

$MyCSVFields = @('Name','Location','Gender')
$CompareResults = Compare-Object $RefObj $DffObj -Property $MyCSVFields -PassThru

$NewOrChangedData = $CompareResults | Where-Object { $_.SideIndicator -eq '=>' } | ForEach-Object { 
    $name = $_.Name
    [PsCustomObject]@{
        ID = ($RefObj | Where-Object { $_.Name -eq $name }).ID
        Name = $name
        Location = $_.Location
        Gender = $_.Gender
        #Sanity check "Compare Indicator" = $_.SideIndicator 
    }
}

$NewOrChangedData

结果：

ID 姓名 地点 性别
-- ---- -------- ------
1 彼得 美国 女
3 玛丽美国女
   汤姆 PI 女
   巴里 CAN 男
