Represents a subscription to a timer event.
Assembly: System.Workflow.Runtime (in System.Workflow.Runtime.dll)
Thetype exposes the following members.
|TimerEventSubscription()||Initializes a new instance of the class.|
|TimerEventSubscription(Guid, DateTime)||Initializes a new instance of the class by using the specified Guid of a workflow instance and the specified expiration DateTime.|
|TimerEventSubscription(Guid, Guid, DateTime)||Initializes a new instance of the class by using the specified subscription Id, the specified Guid of a workflow instance, and the specified expiration DateTime.|
|ExpiresAt||Gets the expected expiration time of the timer associated with this subscription.|
|QueueName||Represents the name of the WorkflowQueue that the WorkflowRuntime sends a message to when the timer subscription expires.|
|SubscriptionId||Unique identifier that represents a timer event|
|WorkflowInstanceId||Identifier of the workflow associated with the timer subscription|
|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 it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (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.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|

objects are added to the timer queue associated with a workflow instance in order to send a message to a specific WorkflowQueue at a specified time. When the time specified by ExpiresAt is reached, the workflow runtime engine sends a message containing the SubscriptionId to the WorkflowQueue specified by QueueName. The timer queue associated with a workflow instance is contained in the TimerCollectionProperty. You can examine TimerCollectionProperty and the WorkflowQueueInfo objects returned by WorkflowInstance.GetWorkflowQueueData to determine which activities are waiting on a specific . The DelayActivity and the SqlWorkflowPersistenceService both use timer event subscriptions to provide part of their functionality.
