public class UnobservedTaskExceptionEventArgs : EventArgs

The UnobservedTaskExceptionEventArgs type exposes the following members.

Public methodUnobservedTaskExceptionEventArgsInitializes a new instance of the UnobservedTaskExceptionEventArgs class with the unobserved exception.

Public propertyExceptionThe Exception that went unobserved.
Public propertyObservedGets whether this exception has been marked as "observed."

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 the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodSetObservedMarks the Exception as "observed," thus preventing it from triggering exception escalation policy which, by default, terminates the process.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

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.
