The more I use PowerShell, the more I become a an automation
fan!!!
PowerShell provides me the ability to automate almost
everything I encounter in my daily work. Most of the time the cmdlets are
available as part of the snapins, but sometimes you need to use the
functionalities in a .NET assembly that should be loaded into the session and utilize
the functionality provided by the classes in these assemblies. To properly
manage the assemblies I’ve created a module, which you can also use for your
work.
function Initialize-Assembly
{
param
(
[Parameter(Mandatory=$true, Position=0, ParameterSetName="Single")]
[ValidateNotNullOrEmpty()]
[string] $Name,
[Parameter(Mandatory=$true, Position=0, ParameterSetName="Array")]
[ValidateNotNullOrEmpty()]
[string[]] $Names
)
switch($PSCmdlet.ParameterSetName)
{
"Single"
{
[void][System.Reflection.Assembly]::LoadWithPartialName($Name)
break
}
"Array"
{
$Names |% { [void][System.Reflection.Assembly]::LoadWithPartialName($_) }
break
}
}
}
function Test-AssemblyLoaded
{
param
(
[Parameter(Mandatory=$true, Position=0, ParameterSetName="Single")]
[ValidateNotNullOrEmpty()]
[string] $Name,
[Parameter(Mandatory=$true, Position=0, ParameterSetName="Array")]
[ValidateNotNullOrEmpty()]
[string[]] $Names
)
switch($PSCmdlet.ParameterSetName)
{
"Single"
{
(Get-AssemblyLoaded |? {$_ -match $Name}) -ne $null
break
}
"Array"
{
$result = $true
$assemblies = Get-AssemblyLoaded
$Names |% {
$assembly = $_
if(($assemblies |? {$_ -match $assembly}) -eq $null)
{
$result = $false
}
}
$result
break
}
}
}
function Get-AssemblyLoaded
{
[System.AppDomain]::CurrentDomain.GetAssemblies()
}
Export-ModuleMember *Assembly*
