How to set private properties of a cluster resource using WMI?

Hi,

I wanted to know if there is an easier way to set or modify private properties of cluster resource using WMI from managed code (C#). One way I can think of is using ExecuteResourceControl Method of the MSCluster_Resource class to invoke CLUSCTL_RESOURCE_SET_PRIVATE_PROPERTIES control code. Is there a simpler way?

Thanks in advance for any help,
Anagha
