powershell import csv data x,y,z to command not working

i call function Set-LogonHours via import-csv

Import-Csv .\data.csv | % {

Result: error

import csv data to command

Make sure the declare the target parameter an array type:

param(
  [Parameter(Mandatory = $True)]
  [ValidateRange(0, 23)]
  [int[]]$TimeIn24Format, # <-- now the parameter can accept multiple integers between 0 and 23
  # ...
)

And then make sure you split the input string into the individual numbers:

Import-Csv .\data.csv | % {
    Set-LogonHours -Identity $_.user -TimeIn24Format $_.time.Split(',') -Monday -Tuesday -Wednesday -Thursday -NonSelectedDaysare NonWorkingDays
}
