.SYNOPSIS Gets the assemblies in the GAC .DESCRIPTION Gets the assemblies in the GAC. Assemblies can be filterd by Name, Version, Culture, PublicKeyToken or ProcessArchitecture. .PARAMETER Name Filter on the Name part. Supports wildcards. .PARAMETER Version Filter on the Version part. Supports wildcards. .PARAMETER Culture Filter on the Culture part. 'neutral' or '' can be used to filter on assemblies without cultures. Supports wildcards. .PARAMETER PublicKeyToken Filter on the PublicKeyToken part. Supports wildcards. .PARAMETER ProcessorArchitecture Filter on the ProcessorArchitecture part. Supports wildcards. .PARAMETER AssemblyName Filter on AssemblyName. Must be fully qualified. See Test-AssemblyNameFullyQualified. .INPUTS [System.Reflection.AssemblyName[]] .EXAMPLE C:\PS> Get-GacAssembly This example returns all assemblies in the GAC. .EXAMPLE C:\PS> Get-GacAssembly -Name System* -Version 2.0.0.0 This example returns all assemblies in the GAC with a name starting with System and version 2.0.0.0. .LINK Test-AssemblyNameFullyQualified .LINK http://powershellgac.codeplex.com #> function Get-GacAssembly { [CmdletBinding(DefaultParameterSetName = 'PartsSet')] [OutputType('System.Reflection.AssemblyName')] param ( [Parameter(Position = 0, ParameterSetName = 'PartsSet')] [ValidateNotNullOrEmpty()] [string[]] $Name, [Parameter(Position = 1, ParameterSetName = 'PartsSet')] [ValidateNotNullOrEmpty()] [string[]] $Version, [Parameter(Position = 2, ParameterSetName = 'PartsSet')] [ValidateNotNullOrEmpty()] [string[]] $Culture, [Parameter(Position = 3, ParameterSetName = 'PartsSet')] [ValidateNotNullOrEmpty()] [string[]] $PublicKeyToken, [Parameter(Position = 4, ParameterSetName = 'PartsSet')] [ValidateNotNullOrEmpty()] [System.Reflection.ProcessorArchitecture[]] $ProcessorArchitecture, [Parameter(Position = 0, Mandatory = $true, ValueFromPipeline = $true, ParameterSetName = 'AssemblyNameSet')] [ValidateNotNullOrEmpty()] [ValidateScript( { Test-AssemblyNameFullyQualified $_ } )] [System.Reflection.AssemblyName[]] $AssemblyName ) process { if ($PsCmdlet.ParameterSetName -eq 'AssemblyNameSet') { $fullNames = @() foreach ($assmName in $AssemblyName) { $fullNames += $assmName.FullyQualifiedName } foreach ($assembly in [PowerShellGac.GlobalAssemblyCache]::GetAssemblies()) { $fullyQualifiedAssemblyName = $assembly.FullyQualifiedName foreach ($fullName in $fullNames) { if ($fullyQualifiedAssemblyName -eq $fullName) { $assembly break } } } } else { foreach ($assembly in [PowerShellGac.GlobalAssemblyCache]::GetAssemblies()) { $hit = $false foreach ($n in $Name) { if ($assembly.Name -like $n) { $hit = $true break } } if ($Name -and -not $hit) { continue } $hit = $false foreach ($v in $Version) { if ($assembly.Version -like $v) { $hit = $true break } } if ($Version -and -not $hit) { continue } $hit = $false foreach ($c in $Culture) { if ($c -eq 'neutral' -and $assembly.CultureInfo.Equals([System.Globalization.CultureInfo]::InvariantCulture)) { $hit = $true break } if ($c -ne 'neutral' -and $assembly.CultureInfo -like $c) { $hit = $true break } } if ($Culture -and -not $hit) { continue } $hit = $false foreach ($p in $PublicKeyToken) { if ($assembly.PublicKeyToken -like $p) { $hit = $true break } } if ($PublicKeyToken -and -not $hit) { continue } $hit = $false foreach ($p in $ProcessorArchitecture) { if ($assembly.ProcessorArchitecture -eq $p) { $hit = $true break } } if ($ProcessorArchitecture -and -not $hit) { continue } $assembly } } } } |
