If you have an enum like this:
namespace Foo { public class Bar { public enum Baz { A = 0, B = 1, C = 2 } } }
You can use this enum from PowerShell with [FQCN+Enum] notation like this:
Add-Type @" namespace Foo { public class Bar { public enum Baz { A = 0, B = 1, C = 2 } } } "@ [System.Enum]::GetNames([Foo.Bar+Baz]) $BazA = [Foo.Bar+Baz]::A $BazA
You can change culture (locale) into English with chcp 437 in Windows 7.
In contrast, You cannot change culture with chcp in Windows 10.
In Windows 10, if you want to execute single PowerShell script in another culture, you can execute the script like this:
[Threading.Thread]::CurrentThread.CurrentUICulture = 'en-US'; .\myscript.ps1
If you want to change culture throughout every command in a PowerShell process, you have to change the culture setting cached in PowerShell runtime with reflection like this:
# example: Set-PowerShellUICulture -Name "en-US" function Set-PowerShellUICulture { param([Parameter(Mandatory=$true)] [string]$Name) process { $culture = [System.Globalization.CultureInfo]::CreateSpecificCulture($Name) $assembly = [System.Reflection.Assembly]::Load("System.Management.Automation") $type = $assembly.GetType("Microsoft.PowerShell.NativeCultureResolver") $field = $type.GetField("m_uiCulture", [Reflection.BindingFlags]::NonPublic -bor [Reflection.BindingFlags]::Static) $field.SetValue($null, $culture) } }
Note: Some cmdlets like Add-Type are not affected this setting.

You can import assemblies (.NET DLLs) in PowerShell like this:
[void][reflection.assembly]::LoadWithPartialName("System.Drawing") New-Object System.Drawing.Drawing2D.GraphicsPath
But you will get an error when you tring to use these assemblies in C# source embedded in PowerShell script. Assemblies loaded with LoadWithPartialName aren't referenced from embedded source.
[void][reflection.assembly]::LoadWithPartialName("System.Drawing") Add-Type @" using System.Drawing.Drawing2D; "@ Add-Type : c:\tmp\_System\ama4povk.0.cs(1) : The type or namespace name 'Drawing2D' could not be found (are you missing a using directive or an assembly reference?) c:\tmp\_System\ama4povk.0.cs(1) : >>> using System.Drawing.Drawing2D; At line:1 char:1 + Add-Type @" + ~~~~~~~~~~~ + CategoryInfo : InvalidData: (Microsoft.Power...peCompilerError:AddTypeCompilerError) [Add-Type], Exception + FullyQualifiedErrorId : SOURCE_CODE_ERROR,Microsoft.PowerShell.Commands.AddTypeCommand Add-Type : Cannot add type. Compilation errors occurred. At line:1 char:1 + Add-Type @" + ~~~~~~~~~~~ + CategoryInfo : InvalidData: (:) [Add-Type], InvalidOperationException + FullyQualifiedErrorId : COMPILER_ERRORS,Microsoft.PowerShell.Commands.AddTypeCommand
With Add-Type, you have to specify assemblies with -ReferencedAssemblies option like this:
Add-Type -ReferencedAssemblies ("System.Drawing") @" using System.Drawing.Drawing2D; "@
You will get error when you run following Maven command from Windows PowerShell:
