System.DirectoryServices.Protocols

I am experimenting with PowerShell code to undelete AD tombstoned objects.

I can search, isolate and map an object to a particular deleted object.

I need to use
System.DirectoryServices.Protocols.DirectoryAttributeModification to perform
the undelete. I am having a lot of trouble actually creating an object of
this type. I have already loaded the relevant assembly and have successfuly
created other objects in SDS.Protocols namespace.

Has anyone successfully acheived this and if so how?

Thanks

The reason you are having trouble creating the type is because the assembly
containing it (System.DirectoryServices.Protocols.dll) isn't loaded.

There's a few ways to load an assembly. The easiest is probably just to use
LoadWithPartialName.

[reflection.assembly]::LoadWithPartialName("system.directoryservices.protocols")

However, that is deprecated which means it will probably be removed in the
next version of the framework. You can also use Assembly.LoadFrom or the
community extensions Resolve-Assembly.

Thank you for your reply but I am afraid that this is not correct.

I have loaded the assembly and sucessfully created other objects in that
namespace as stated in the original post. I have tried loading the assembly
using LoadWithPartialname and Load and Resolve-Assembly. If I hadn't loaded
the assembly I would have received the error message telling me that the
assembly was not loaded when I tried to create the object.

The issue appears to be around the constructor of the class. Easiest way to
resolve this in the short term is write a cmdlet to perform the modification
I suppose as I have some example code

Yes, you didn't mention what error you received.

Maybe. An easier way would probably be to use System.Activator. However,
you shouldn't be having any trouble creating the object. I can't seem to
repro any error on my machine.

What error are you getting?
