Remarks

Using the PolicyCategory object you can:

Create a policy category to which target objects can subscribe.
Specify the policy category to use in a subscription

Examples

PolicyCategorySubscription policyCatSub = new PolicyCategorySubscription(ps);
policyCatSub.PolicyCategory = category;
policyCatSub.TargetType = targetType;
policyCatSub.Target = targetObject;
policyCatSub.Create();
