Start by studying the documentation: System.Management Namespace | Microsoft Docs[^]. System Management is a somewhat advanced namespace, maybe you should start with something easier.

Basically, stop using var unless you need to.
When you write this:

C#

var objWmiService = Interaction.GetObject(@"Winmgmts:\\.\root\cimv2");

objWmiService is type defined by context as the return type for Interaction.GetObject which - understandably - is an object because the return value could be anything.

If you'd written it using a " proper" type name instead, you'd have got an error message which would have been a lot more specific:

C#

MyActuialType objWmiService = Interaction.GetObject(@"Winmgmts:\\.\root\cimv2");

It would have told you that you need to cast the return value to your actual type before you can access any field, properties, or methods.

So use a "proper" type, and then use as to cast it, checking the casted value for null in case it isn't what you expected.
