Simple Question about WMI in C#

[David zha0]

Hi,

I just want to write a small program to do some job on the remote system
with WMI, and my question is how can I deal with the WMI connection? To
connect the remote host once we need or just keep the connection alive?

I think maybe I can use a singleton pattern here, but I'm not sure what
the singleton should return, a ConnectionOptions or a ManagementScope?

David,

I don't see what having a singleton here does for you. Perhaps if you
wanted to keep an open/persistant connection, then I can understand. In
that case, I would probably go with a ManagementScope instance. If you
return a ConnectionOptions instance, you will probably keep creating the
ManagementScope instance for your operations over and over again, and that's
extra code you don't have to write.

Nicholas:

Thanks a lot for your reply, I meant to persist the connection during almost
the
whole lifetime of the program and, the ConnectionOptions won't be changed.

I think it is clear that I should keep an ManagementScope object...
Sorry for the stupid question

Thanks again.
