问题 Is it a way to detect if there is any file added in a folder? Include the sub-folder. For example, check if any text file *.txt is added in folder c:\data-files\ or its sub-folders. The folder can be shared folder of another machine too. 回答1: Perhaps you are confused on the types of events that are triggered: http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher_events(v=vs.110).aspx This should work, taken from the link above and modified for your requirements: #By BigTeddy 05

问题 I'm looking to pad IP addresses with 0's example 1.2.3.4 -> 001.002.003.004 50.51.52.53 -> 050.051.052.053 Tried this: [string]$paddedIP = $IPvariable [string]$paddedIP.PadLeft(3, '0') Also tried split as well, but I'm new to powershell... 回答1: You can use a combination of .Split() and -join . ('1.2.3.4'.Split('.') | ForEach-Object {$_.PadLeft(3,'0')}) -join '.' With this approach, you are working with strings the entire time. Split('.') creates an array element at every . character. .PadLeft

问题 I need to automatically print a PDF file to a file (need to have printer driver set all the print options like stapling, duplexing, etc) on a network folder so other employees can print the .prn file from networked printers. After a fair bit of searching I have found that it is possible to have PowerShell print the PDF using Start-Process -FilePath document.pdf -Verb Print which invokes the appropriate application to print the PDF but doesn't allow me to check the "Print to file" box. I could

问题 Does anyone have an example of mocking a dot-sourced class function with Pester 5 and PowerShell 7? Thank you. Edit: example Classes\MyClass.ps1: class MyClass { [void] Run() { Write-Host "Class: Invoking run..." } } MyModule.psm1: # Import classes . '.\Classes\MyClass.ps1' # Instantiate classes $MyClass = [MyClass]::new() # Call class function $MyClass.Run() 回答1: Pester only mocks commands - not classes or their methods. The easiest way to "mock" a PowerShell class for method dispatch

问题 This question already has answers here : How do I call New-Object for a constructor which takes a single array parameter? (2 answers) Closed 2 years ago . It seems that there is a bug in the O-O support in PowerShell . When instantiating an object of a class with a constructor that accepts a List< T > and this is the only parameter , PowerShell cannot find a proper constructor. Code sample: class MyClass { MyClass( #[int]$i, [System.Collections.Generic.List[string]] $theparams) { } }
