PowerShell DSC加载程序集

Question

I have written a class based DSC resource. In this resource I need an assembly(Microsoft.SqlServer.Smo.dll). I have tried to load the assembly with the manifest file: like that: RequiredAssemblies = @("Microsoft.SqlServer.Smo.dll")

Now I have the problem that when I want to write my DSC Configuration definion, I can't load my dsc resource because of the erromessage: Unable to find type [Microsoft.SqlServer.Smo.Login]

Picture of the errormessage:

How can I load an assembly into my dsc session?

Answer 1

Make sure that assembly is in the same folder as your module, and then call it like this (no dll): RequiredAssemblies = @("Microsoft.SqlServer.Smo")

If that doesn't work, you can use reflection and load it into your AppDomain when the module is imported.

$assembly = Join-Path $PSScriptRoot -ChildPath 'Microsoft.SqlServer.Smo.dll'
$result = [System.Reflection.Assembly]::LoadFile($assembly)
if($result -eq $null)
{
    throw New-Object System.Exception("Failed to Microsoft.SqlServer.Smo assembly")            
}
