我有一个包含100多列的CSV。有时当我运行脚本时,我想选择几列,但有时我需要所有列。它将被写入|管道分隔文件。
是否有Import-CSV的命令/属性可以在不指定所有标题的情况下获得完整行?
我尝试了下面的代码,但我有一个挂|当我想要所有列时,在行上管道。
# powershell -ExecutionPolicy ByPass -File .\test.ps1 -NoExit -AllColumns
param(
[switch]$AllColumns = $false
)
$writer = New-Object IO.StreamWriter('output.txt')
Import-Csv 'test.csv' | ForEach-Object {
$writeLine = ""
if($_.("Name") -eq "John") {
if($AllColumns) {
#$writeLine = All Columns with '|' delimiter
foreach ($property in $_.PSObject.Properties) {
$writeLine = ($writeLine + $property.Value + '|')
# Or this - $writeLine = ($writeLine, $property.Value -join '|')
}
} else {
$writeLine = ($_.("Name"), $_.("Code") -join '|')
}
}
$writer.WriteLine($writeLine)
}
$writer.Close()

我认为您正在寻找Select-Object cmdlet。示例功能
Import-Csv -Path 'C:\2Users50columns.csv' `
| Select-Object -Property 'Name','Classification','Age'
Name : Esuriency
Classification : Member
Age : 35 minutes ago
Name : Shawn
Classification : Member
Age : 27
所以你要插入一个Select-Object:
Import-Csv -Path 'text.csv' | Select-Object ... | Foreach-Object {
