我有一个CSV文件，其中有一个名为‘art’的列：

sequence art last  first  address city st     zip
-------- --- ----  -----  ------- ---- --     ---
1        3S  Doe   John   123     Any  Street AnyTown
6        3S  Doe   John   128     Any  Street AnyTown
2        OG  Dow   Jane   124     Any  Street AnyTown
7        OG  Dow   Jane   129     Any  Street AnyTown
3        OGF Cool  Joe    125     Any  Street AnyTown
8        OGF Cool  Joe    130     Any  Street AnyTown
4        SLV Cool  Carol  126     Any  Street AnyTown
9        SLV Cool  Carol  131     Any  Street AnyTown
5        SMP Bravo Johnny 127     Any  Street AnyTown
10       SMP Bravo Johnny 132     Any  Street AnyTown

我正在寻找一种将‘art’列的值存储到变量中的方法。请原谅我，因为我还在学习PowerShell。这是我到目前为止掌握的代码：

If (Test-Path D:\mhWork\_Auto\_Print\c1478_tpl_snap\data\Art_cProofs.csn){
$source=Get-ChildItem "D:\mhWork\_Auto\_Print\c1478_tpl_snap\data\Art_cProofs.csn" | select  -Last 1
$artTag = 'D:\mhWork\_Auto\_Print\c1478_tpl_snap\data\Art_cProofs.csn'
$artTag1 = Import-Csv $artTag | Select-Object -ExpandProperty art -First 1
$artTag2 = Import-Csv $artTag | Select-Object -ExpandProperty art -Second 2
$artTag3 = Import-Csv $artTag | Select-Object -ExpandProperty art -Third 3
$artTag4 = Import-Csv $artTag | Select-Object -ExpandProperty art -Fourth 4
$artTag5 = Import-Csv $artTag | Select-Object -ExpandProperty art -Fifth 5
$JobID = "TPL_" + ($aJobNum)

If (Test-Path cProofs0001.pdf){
Rename-Item cProofs0001.pdf "$($JobID)_$($artTag1)_cProofs.pdf"}
If (Test-Path cProofs0002.pdf){
Rename-Item cProofs0002.pdf "$($JobID)_$($artTag2)_cProofs.pdf"}
If (Test-Path cProofs0003.pdf){
Rename-Item cProofs0003.pdf "$($JobID)_$($artTag3)_cProofs.pdf"}
If (Test-Path cProofs0004.pdf){
Rename-Item cProofs0004.pdf "$($JobID)_$($artTag4)_cProofs.pdf"}
If (Test-Path cProofs0005.pdf){
Rename-Item cProofs0005.pdf "$($JobID)_$($artTag5)_cProofs.pdf"}
}

正如你在‘art’栏中看到的，有5个不同的值。在我通过$artTag1之前，代码运行良好。预期的结果将重命名以下文件。

cProofs0001.pdf - to - 123456_TPL_3S_cProofs.pdf
cProofs0002.pdf - to - 123456_TPL_OG_cProofs.pdf
cProofs0003.pdf - to - 123456_TPL_OGF_cProofs.pdf
cProofs0004.pdf - to - 123456_TPL_SLV_cProofs.pdf
cProofs0005.pdf - to - 123456_TPL_SMP_cProofs.pdf

我想我可能需要使用Get-Content或For-Each循环。
