Question

这与我问的here非常相似，只有两个文件，反向搜索。

解释

考虑到下面显示的两个文件（test1.csv和test2.csv），我需要将LoginNumber中的test1.csv与来自UserIDNumber的{{1}}进行匹配}。

找到匹配项后，请抓取test2.csv中ReportExpirationDate栏中的值。

如果test2.csv的值中没有任何内容，则该值应从ReportExpirationDate更改为$null。

最后，在匹配User Not Found和test1.csv时，我们需要在ExpirationDateFromReport列附加LoginNumber。

注意：我在这个问题的列之间添加了空格，因此更容易查看和查看我在说什么。这些文件没有空格......

UserIDNumber：

test1.csv

"SamAccountName","LoginNumber","Type,"ContractorDomain","ExpirationDateFromAd" "jd12395" ,"0031482" ,"H" ,"P12345" ,"2016/06/26 13:59" "jwet" ,"" ,"P" ,"A52671" ,"" "x023js" ,"0418230" ,"P" ,"" ,"" "1b3gas5" ,"2167312" ,"H" ,"425126" ,"2015/11/17 12:00" "632g1fsa" ,"0052142" ,"L" ,"" ,"" "x023js" ,"0720182" ,"P" ,"" ,"2016/06/26 13:59" "4126hs" ,"" ,"H" ,"" ,"2016/08/12 4:32" "axv" ,"2058194" ,"A" ,"L21514" ,"2016/03/11 7:31"：

test2.csv

test1.csv的最终结果应如下所示：

UserIDNumber,AccountDescriptionDetails,ReportExpirationDate
0052142     ,Company CEO              ,
0418230     ,Software Developer       ,20161124
0031482     ,Software Developer       ,
2167312     ,Project Manager          ,20151117
0720182     ,QA Tester                ,20160128
1840237     ,Accountant Administrator ,
0000418     ,Program Manager          ,20160309

由于某种原因，附加列的所有值都是空白的。

Answer 1

帐户说明不是唯一的，也不会存在于test1.csv中，因此它们不会作为哈希表的关键字工作。但是，用户ID可以正常工作。

$accountStatus = @{}
Import-Csv 'C:\Temp\test2.csv' | ForEach-Object {
  $accountStatus[$_.UserIDNumber] = $_.ReportExpirationDate
}

使用if语句处理空的报告到期日期：

Import-Csv 'C:\Temp\test2.csv' | ForEach-Object {
  $accountStatus[$_.UserIDNumber] = if ($_.ReportExpirationDate) {
    $_.ReportExpirationDate
  } else {
    'No Date Found'
  }
}

然后将新列添加到test1.csv：

Import-Csv 'C:\Temp\test1.csv' |
  Select-Object -Property *, @{n='ExpirationDateFromReport';e={
    if ($accountStatus.ContainsKey($_.LoginNumber)) {
      $accountStatus[$_.LoginNumber]
    } else {
      'User Match Not Found'
    }
  }} | Export-Csv 'C:\Temp\final.csv' -NoType

在2个CSV文件之间的新列中查找匹配和添加值
