PowerShell ISE中的Import-Csv锁定文件

Question

I want to read some CSV files with PowerShell and then save them in the same spot with a different delimiter:

$content = (import-csv -path $filepath -Encoding utf8 -Delimiter ",") 
write-host $(& ..\DLLs\Handle\handle.exe $filepath)
remove-item $filepath
export-csv ...

I fails at the deleting the file step. I have added the handle.exe Debug information as suggested in PowerShell unlock/unload imported CSV and it indeed shows that the powershell_ise.exe still has a handle on the file. When the script finishes, I can delete or rename it as I wish.

How to get around this?

Answer 1

Try to omit the Remove-Item cmdlet since its probably not necessary. The Import-CSV cmdlet shouldn't lock the file and I can't reproduce that. However, you could try to use the Get-Content to read the file and pipe it to the ConvertFrom-Csv cmdlet (note: you don't need to explicit specify the delimiter for a comma separated CSV):

$content = Get-Content $filepath -raw | ConvertFrom-Csv

Answer 2

I got it now. My particular setup, that part, which I had omitted, because I didn't think it was necessary, was the culprit.

The above code was running within a pipeline, part of which was searching in the file for a certain text

ls *.csv | select-string "someText" | % { do the CSV Stuff }

What was locking then, was the select-string command, not the import-csv.
