WMI and C#

[Bo Hunter]

I need a way to get network status like connected or disconnected. I have generated a class with mgmtclassgen and it throws exceptions when tring to create the class. What is the best way to do this? Thank you Bo Hunter Me

Are you using the System.Management and System.Management.Instrumentation namespaces? If so, then you can just use a WQL query with the ManagementQuery object and query whatever you want.

I am assuming you are using WMI to get the network status. The problem you may be that certain adapters do not have an actual instance when you check the status. For example the WAN Miniport (PPTP) will not have a status all the time (if it does at all). WHen you loop through your ManagementCollection you will get a NullReferenceException - Bo Hunter wrote: object ref not set to an instance object ref not set to an instance. To get around this you should catch the error, or narrow your WQL. If there is a certain adapter you are checking for let me know. I will post some code. I hope this is along the lines of what you are after. Matt is a network administrator for an insurance company in the midwest. He is shamelessly looking for Windows programming side work.
