如何使用 PowerShell 中的 Import-csv 处理 CSV 文件的动态列

Question

CSV file does not have headers, Column may differ each time. I want to compare with first column of csv file, but while exporting I would display the full row.

$getErrorCodes= {102,103}

CSV FILE( No headers)
101,101,101
102,102,102

Here is my code

Import-Csv $CSVFile -Header col1 | Where-Object {!($getErrorCodes.Contains($_.col1)) } | Export-Csv "resultfile.csv"

Current output
101

Expected output
101,101,101

For dynamic header, I used like this. Dynamically will change $headers variable accordingly column count on csv.

$headers = 'Col1,Col2,Col3'

$headercolumns = $headers.ToString().Split(",") 
  
Import-Csv $CSVFile -Header  $headercolumns | Where-Object {!($getErrorCodes.Contains($_.col1)) } | Export-Csv  "resultfile.csv"
