Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)

Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

TrackingExtract is the abstract base class from which the ActivityDataTrackingExtract class and the WorkflowDataTrackingExtract class are derived. An ActivityDataTrackingExtract specifies a field or a property to be extracted from the activity associated with a tracking event and a WorkflowDataTrackingExtract specifies a field or a property to be extracted from the root activity of the workflow instance.
