是否有更好的方法使用Powershell将标头添加到CSV文件？

Question

有没有更有效的方法将标头添加到CSV文件，而不是对其进行硬编码？

$Importfile = Import-csv $path$filename -header H1, H2, H3, H4, H5, H6, H7 #add headers to csv file

Answer 1

这是一种自动为没有CSV文件的标题行生成标题行的方法。它计算文件第一行中的项目以生成标题行。[ 咧嘴 ]

$FileName = "$env:TEMP\Alex_-_Headerless.csv"
$Delimiter = ','

#region >>> create a headerless CSV file to work with
#    remove this section when you are ready to do stuff for real
$HeaderlessCSV = @'

'@ | Set-Content -LiteralPath $FileName
#endregion >>> create a headerless CSV file to work with

$ColumnCount = @((Get-Content -LiteralPath $FileName -TotalCount 1).Split($Delimiter)).Count
$HeaderLine = foreach ($Index in 1..$ColumnCount)
    {
    'Col_{0}' -f $Index
    }

$InStuff = Import-Csv -Delimiter $Delimiter -Header $HeaderLine -LiteralPath $FileName

$InStuff

输出...

Col_1 Col_2 Col_3  Col_4
