<# .SYNOPSIS Imports a .NET dll file into memory .DESCRIPTION Imports a .NET dll file into memory, by creating a copy (temporary file) and imports it using reflection .PARAMETER Path Path to the dll file you want to import Accepts an array of strings .PARAMETER UseTempFolder Instruct the cmdlet to create the file copy in the default temp folder This switch can be used, if writing to the original folder is not wanted or not possible .EXAMPLE PS C:\> Import-AssemblyFileIntoMemory -Path "C:\AOSService\PackagesLocalDirectory\Bin\Microsoft.Dynamics.BusinessPlatform.ProductInformation.Framework.dll" This will create an new file named "C:\AOSService\PackagesLocalDirectory\Bin\Microsoft.Dynamics.BusinessPlatform.ProductInformation.Framework.dll_shawdow.dll" The new file is then imported into memory using .NET Reflection. After the file has been imported, it will be deleted from disk. .EXAMPLE PS C:\> Import-AssemblyFileIntoMemory -Path "C:\AOSService\PackagesLocalDirectory\Bin\Microsoft.Dynamics.BusinessPlatform.ProductInformation.Framework.dll" -UseTempFolder This will create an new file named "Microsoft.Dynamics.BusinessPlatform.ProductInformation.Framework.dll_shawdow.dll" in the temp folder The new file is then imported into memory using .NET Reflection. After the file has been imported, it will be deleted from disk. .NOTES Author: Mötz Jensen (@Splaxi) #> function Import-AssemblyFileIntoMemory { [CmdletBinding()] [OutputType()] param ( [Parameter(Mandatory = $true, Position = 1)] [string[]] $Path, [switch] $UseTempFolder ) if (-not (Test-PathExists -Path $Path -Type Leaf)) { Stop-PSFFunction -Message "Stopping because unable to locate file." -StepsUpward 1 return } foreach ($itemPath in $Path) { if ($UseTempFolder) { $filename = Split-Path -Path $itemPath -Leaf $shadowClonePath = Join-Path $env:TEMP "$filename`_shadow.dll" } else { $shadowClonePath = "$itemPath`_shadow.dll" } try { Write-PSFMessage -Level Debug -Message "Cloning $itemPath to $shadowClonePath" Copy-Item -Path $itemPath -Destination $shadowClonePath -Force Write-PSFMessage -Level Debug -Message "Loading $shadowClonePath into memory" $null = [AppDomain]::CurrentDomain.Load(([System.IO.File]::ReadAllBytes($shadowClonePath))) } catch { Write-PSFMessage -Level Host -Message "Something went wrong while working against the database" -Exception $PSItem.Exception Stop-PSFFunction -Message "Stopping because of errors" return } finally { Write-PSFMessage -Level Debug -Message "Removing $shadowClonePath" Remove-Item -Path $shadowClonePath -Force -ErrorAction SilentlyContinue } } } |
