我制作了两个样例文件：test1.csv：

header
"10.0139_ssrn.3771318356"
"10.1001_archdermatol.2012.418"
"10.1001_archinte.165.15.17376"
"10.1001_archinternmed.2012.127"
"10.1001_archopht.123.1.2512"
"10.1001_archoto.2010.12197"
"10.1001_archotol.127.1.25"

Est2.csv：

header
"10.0139_ssrn.3771318356"
"10.1001_archdermatol.2012.418"
"10.1001_archinte.165.15.1737"
"10.1001_archinte.165.15.1743"
"10.1001_archinte.165.18.2142"
"10.1001_archinternmed.2012.127"

然后循环文件1中的所有项，并检查它们是否出现在文件2中：

$csv1 = Import-Csv "E:\users\temp\test1.csv"
$csv2 = Import-Csv "E:\users\temp\test2.csv"
$elementsToKeep = @()
foreach ($element1 in $csv1) {
    foreach ($element2 in $csv2) {
        if ($element1.header -eq $element2.header) {
            $elementsToKeep += $element1
        }
    }
}

$elementsToKeep | Export-Csv "E:\users\temp\output.csv" -NoTypeInformation

Output.csv的内容：

"header"
"10.0139_ssrn.3771318356"
"10.1001_archdermatol.2012.418"
"10.1001_archinternmed.2012.127"

尝试以下操作：

$filename = "c:\temp\test.csv"
$list1 = @("10.0139_ssrn.3771318", ` 
          "10.1001_archdermatol.2012.418", ` 
          "10.1001_archinte.165.15.1737", `
          "10.1001_archinte.165.15.1743", `
          "10.1001_archinte.165.18.2142", `
          "10.1001_archinternmed.2012.127")
$csv = Import-Csv -Path $filename -Header 'number', 'name'
$csv | Format-Table
$filteredData = $csv.Where({$list1.Contains($_.name)})
$filteredData | Format-Table

以下是输出
