public class TimerEventSubscriptionCollection : ICollection, 
	IEnumerable

The TimerEventSubscriptionCollection type exposes the following members.

  NameDescription
Public propertyCountGets the number of TimerEventSubscription objects in the timer queue.
Public propertyIsSynchronizedGets a value that indicates whether the access to the TimerEventSubscriptionCollection is synchronized (thread safe).
Public propertySyncRootGets an object that can be used to synchronize access to the TimerEventSubscriptionCollection.

  NameDescription
Public methodAddAdds a TimerEventSubscription to the timer queue.
Public methodCopyToCopies the TimerEventSubscriptionCollection elements to an existing one-dimensional Array, starting at the specified array index.
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 methodGetEnumeratorReturns an enumerator that iterates through the TimerEventSubscriptionCollection.
Public methodGetHashCodeServes as the default hash function. (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 methodPeekReturns the TimerEventSubscription at the beginning of the timer queue without removing it.
Public methodRemove(Guid)Removes the TimerEventSubscription that has the specified subscription id from the timer queue.
Public methodRemove(TimerEventSubscription)Removes the TimerEventSubscription from the timer queue.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

NoteNote

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

A TimerEventSubscriptionCollection represents the queue of TimerEventSubscription objects associated with a workflow instance and provides methods to manage this queue. Subscriptions are ordered in the queue based on their ExpiresAt values; those with smaller ExpiresAt values are positioned before those with larger ExpiresAt values. You can use the methods provided by this class to manage the collection of active timer event subscriptions exposed by TimerCollectionProperty for each workflow instance. You can use Add or Remove to add or remove subscriptions from the timer queue. Whenever the first element in the timer queue changes, the WorkflowSchedulerService is called to cancel the timer event that was previously at the beginning of the queue and schedule the new timer event.
