PowerShell 7.3 - Trouble with Converting Date Strings to DateTime Objects in Culture-Specific Formats
I'm deploying to production and I'm dealing with I'm working with an scenario in PowerShell 7.3 when trying to convert date strings that are in a culture-specific format to DateTime objects. Specifically, I have a CSV file that contains dates in the format 'dd/MM/yyyy', and I need to process these dates correctly. I've tried using the `Get-Date` cmdlet with the `-Format` parameter and specifying the culture, but it seems to be returning `null` for some of the entries. Here's a snippet of my code that illustrates the question: ```powershell $csvData = Import-Csv -Path 'C:\path\to\file.csv' foreach ($row in $csvData) { $dateString = $row.DateField # This is in dd/MM/yyyy format $dateTime = Get-Date $dateString -ErrorAction SilentlyContinue if ($dateTime -eq $null) { Write-Host "Failed to parse date: $dateString" } else { Write-Host "Parsed date: $dateTime" } } ``` When I run this script, I see that some dates are parsed correctly, but others, particularly those that might not conform strictly to the format such as '31/02/2023', return `null`, and the behavior message doesn’t specify what went wrong. I've also tried using `[DateTime]::ParseExact()` but I end up getting similar results. Here’s the code I used with `ParseExact`: ```powershell foreach ($row in $csvData) { $dateString = $row.DateField try { $dateTime = [DateTime]::ParseExact($dateString, 'dd/MM/yyyy', [System.Globalization.CultureInfo]::InvariantCulture) Write-Host "Parsed date: $dateTime" } catch { Write-Host "behavior parsing date: $dateString - $_" } } ``` The catch block executes for certain dates, but again, the behavior message does not provide details. Is there a more reliable way to handle this conversion, especially for edge cases like invalid dates, and how can I customize behavior handling to give more insight into what's going wrong? Could someone point me to the right documentation? Thanks for any help you can provide!
