如何格式化使用Powershell import-csv获取的数据

Question

I imported a csv file using import-csv. I only wanted the account number from the list.

I used

$Numbers = Import-Csv csv.csv |Select-Object -ExpandProperty 'Account Number' |Where-Object {$_ -ne "0"} | Out-Null 

but i want enclose the account number with "'" and separate the account number with ",". Ideally the list should look like: 'account1','account2',...,'accountlast'. I could not manipulate the $ number variable like array.

Answer 1

You are very close. You can import the csv, select the object, then use a foreach to format each object, and finally write to the host with one line instead of breaks for each.

Import-Csv csv.csv | Select-Object -ExpandProperty 'Account Number' | Where-Object {$_ -ne "0"} | ForEach{"'" + $_ + "', "} | Write-Host -NoNewLine

Answer 2

Some string manipulation and a -join should be able to get this for you. Although an array which is returned from Import-Csv csv.csv | Select-Object -ExpandProperty 'Account Number' | Where-Object {$_ -ne "0"} Import-Csv csv.csv | Select-Object -ExpandProperty 'Account Number' | Where-Object {$_ -ne "0"} Import-Csv csv.csv | Select-Object -ExpandProperty 'Account Number' | Where-Object {$_ -ne "0"} would be considered more versatile!

$numbers = "'{0}'" -f ((Import-Csv csv.csv | Select-Object -ExpandProperty 'Account Number' | Where-Object {$_ -ne "0"}) -join "','")

Join the account numbers with ',' and then we use the format operator to enclose that into the outer single quotes.
