问题 I tried to use predefined variables like $PSVersionTable or $PSScriptRoot in a class method. They failed with the error message Variable is not assigned in the method. Example: Class Foo { [String]$Version GetVersion() { If ($PSVersionTable) { $this.Version = $PSVersionTable.PSVersion } } } But why? 回答1: Class Foo { [String] $Version GetVersion() { if ($global:PSVersionTable) { $this.Version = $global:PSVersionTable.PSVersion } } } $foo = [Foo]::new() $foo.GetVersion() Write-Host $foo.Version

问题 I am trying to create a external network drive using PowerShell 5.0. I Need those drive to display in My Computer. For that purpose I am using this follow command. New-PSDrive -Name "X" -PSProvider FileSystem -Root "\\192.168.0.1\hde_path" -Persist Is there anything wrong with this command? Because as per my understanding if I use -Persist it is should be displayed in the My Computer window. After using this, the mapped drive X: is not being displayed in My Computer. Thanks in Advance! 回答1:
