Delay Class
Creates a timer for a specified duration, using a TimerExtension.
Assembly: System.Activities (in System.Activities.dll)
System.Activities.Activity
System.Activities.NativeActivity
System.Activities.Statements.Delay
| Name | Description | |
|---|---|---|
![]() | Delay() | Creates a new instance of the Delay activity. |
| Name | Description | |
|---|---|---|
![]() | CacheId | Gets the identifier of the cache that is unique within the scope of the workflow definition.(Inherited from Activity.) |
![]() | DisplayName | Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.(Inherited from Activity.) |
![]() | Duration | The duration of the timer that the Delay activity creates. If the duration is set to P:System.TimeSpan.MaxValue, the delay is infinite. |
![]() | Id | Gets an identifier that is unique in the scope of the workflow definition.(Inherited from Activity.) |
![]() | ImplementationVersion | Gets or sets the implementation version of the activity.(Inherited from NativeActivity.) |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | ShouldSerializeDisplayName() | Indicates whether the DisplayName property should be serialized.(Inherited from Activity.) |
![]() | ToString() | Returns a String that contains the Id and DisplayName of the Activity.(Inherited from Activity.) |
When the activity’s timer expires, the Delay activity completes its execution. If a workflow instance persists while a Delay activity has an outstanding timer, then an T:System.ServiceModel.Activities.Description.ITimerExpiredNotification standard endpoint must be configured to receive notification that the timer has expired.
The following code sample demonstrates creating a Delay activity. This example is from the Using the Pick Activity sample.
static Activity CreateWF() { Variable<string> name = new Variable<string>(); Sequence body = new Sequence { Variables = { name }, Activities = { new WriteLine { Text = "What is your name? (You have 5 seconds to answer)" }, new Pick { Branches = { new PickBranch { Trigger = new ReadString { Result = name, BookmarkName = bookmarkName }, Action = new WriteLine { Text = new InArgument<string>(env => "Hello " + name.Get(env)) } }, new PickBranch { Trigger = new Delay { Duration = TimeSpan.FromSeconds(5) }, Action = new WriteLine { Text = "Time is up." } } } } } }; return body; }
