Methods

	Name	Description
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SetObserved	Marks the Exception as "observed," thus preventing it from triggering exception escalation policy which, by default, terminates the process.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

The Exception property is used to examine the exception without marking it as observed, whereas the SetObserved method is used to mark the exception as observed. Marking the exception as observed prevents it from triggering exception escalation policy which, by default, terminates the process.
