function Find-PSMDType { <# .SYNOPSIS Searches assemblies for types. .DESCRIPTION This function searches the currently imported assemblies for a specific type. It is not inherently limited to public types however, and can search interna just as well. Can be used to scan for dependencies, to figure out what libraries one needs for a given type and what dependencies exist. .PARAMETER Name Default: "*" The name of the type to search for. Accepts wildcards. .PARAMETER FullName Default: "*" The FullName of the type to search for. Accepts wildcards. .PARAMETER Assembly Default: (Get-PSMDAssembly) The assemblies to search. By default, all loaded assemblies are searched. .PARAMETER Public Whether the type to find must be public. .PARAMETER Enum Whether the type to find must be an enumeration. .PARAMETER Static Whether the type to find must be static. .PARAMETER Implements Whether the type to find must implement this interface .PARAMETER InheritsFrom The type must directly inherit from this type. Accepts wildcards. .PARAMETER Attribute The type must have this attribute assigned. Accepts wildcards. .EXAMPLE Find-PSMDType -Name "*String*" Finds all types whose name includes the word "String" (This will be quite a few) .EXAMPLE Find-PSMDType -InheritsFrom System.Management.Automation.Runspaces.Runspace Finds all types that inherit from the Runspace class #> [CmdletBinding()] Param ( [string] $Name = "*", [string] $FullName = "*", [Parameter(ValueFromPipeline = $true)] [System.Reflection.Assembly[]] $Assembly = (Get-PSMDAssembly), [switch] $Public, [switch] $Enum, [switch] $Static, [string] $Implements, [string] $InheritsFrom, [string] $Attribute ) begin { $boundEnum = Test-PSFParameterBinding -ParameterName Enum $boundPublic = Test-PSFParameterBinding -ParameterName Public $boundStatic = Test-PSFParameterBinding -ParameterName Static } process { foreach ($item in $Assembly) { if ($boundPublic) { if ($Public) { $types = $item.ExportedTypes } else { # Empty Assemblies will error on this, which is not really an issue and can be safely ignored try { $types = $item.GetTypes() | Where-Object IsPublic -EQ $false } catch { Write-PSFMessage -Message "Failed to enumerate types on $item" -Level InternalComment -Tag 'fail','assembly','type','enumerate' -ErrorRecord $_ } } } else { # Empty Assemblies will error on this, which is not really an issue and can be safely ignored try { $types = $item.GetTypes() } catch { Write-PSFMessage -Message "Failed to enumerate types on $item" -Level InternalComment -Tag 'fail', 'assembly', 'type', 'enumerate' -ErrorRecord $_ } } foreach ($type in $types) { if ($type.Name -notlike $Name) { continue } if ($type.FullName -notlike $FullName) { continue } if ($Implements -and ($type.ImplementedInterfaces.Name -notcontains $Implements)) { continue } if ($boundEnum -and ($Enum -ne $type.IsEnum)) { continue } if ($InheritsFrom -and ($type.BaseType.FullName -notlike $InheritsFrom)) { continue } if ($Attribute -and ($type.CustomAttributes.AttributeType.Name -notlike $Attribute)) { continue } if ($boundStatic -and ($Static -ne ($type.IsAbstract -and $type.IsSealed))) { continue } $type } } } } |
