如何在此上使用组对象? [英] How to use Group-Object on this?

问题描述

我正在尝试从 $ f 中获取与 $ table4 中的帐户不匹配的所有帐户到 $ accounts 中.但是我还需要检查入住人数是否匹配.

I am trying to get all the accounts from $f which do not match the accounts in $table4 into $accounts. But I need to also check if the occupancy number matches or not.

CSV $ f :

Account_no |occupant_code
-----------|------------
12345      |    1
67890      |    2
45678      |    3

DataTable $ table4

DataTable $table4

Account_no |occupant_code
-----------|------------
12345      |   1
67890      |   1
45678      |   3

当前代码:

$accounts = Import-Csv $f |
            select account_no, occupant_code |
            where { $table4.account_no -notcontains $_.account_no }

这需要做的是检查 occupant_code 是否不匹配，即:

What this needs to do is to check that occupant_code doesn't match, i.e.:

• 12345 : $ f 和 $ table4 的帐户和居住者匹配；因此它被忽略了
• 67890 :帐户匹配 $ table4 ，但是occupancy_code不匹配，因此将其添加到 $ accounts .

• 12345: account and occupant from $f and $table4 match; so it's ignored
• 67890: account matches $table4, but occupancy_code does not match, so it is added to $accounts.

当前结果:
所需结果: 67890

我相信我需要使用 Group-Object ，但是我不知道如何正确使用它.

I believe I need to use Group-Object, but I do not know how to use that correctly.

我尝试过:

Import-Csv $f |
    select account_no, occupant_code |
    Group-Object account_no |
    Where-Object { $_.Group.occupant_code -notcontains $table4.occupant_code }

推荐答案

比较对象?

csv1.csv:

Account_no,occupant_code
12345,1
67890,2
45678,3

csv2.csv:

Account_no,occupant_code
12345,1
67890,1
45678,3

PowerShell命令:

PowerShell command:

Compare-Object (Import-Csv .\csv1.csv) (Import-Csv .\csv2.csv) -Property occupant_code -PassThru

输出:

Account_no occupant_code SideIndicator
---------- ------------- -------------
67890      1             =>
67890      2             <=
