Examples

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;
}

Remarks

When the activity's timer expires, the Delay activity completes its execution.

Constructors

Delay()

Creates a new instance of the Delay activity.

Properties

CacheId

Gets the identifier of the cache that is unique within the scope of the workflow definition.

(Inherited from Activity)
CanInduceIdle

Gets or sets a value that indicates whether the activity can cause the workflow to become idle.

(Inherited from NativeActivity)
Constraints

Gets a collection of Constraint activities that can be configured to provide validation for the Activity.

(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 MaxValue, the delay is infinite.

Id

Gets an identifier that is unique in the scope of the workflow definition.

(Inherited from Activity)
Implementation

The execution logic of the activity.

(Inherited from NativeActivity)
ImplementationVersion

Gets or sets the implementation version of the activity.

(Inherited from NativeActivity)

Methods

Abort(NativeActivityAbortContext)

When implemented in a derived class, takes actions in response to the activity being aborted.

(Inherited from NativeActivity)
CacheMetadata(ActivityMetadata)

Not implemented. Use the CacheMetadata(NativeActivityMetadata) method instead.

(Inherited from NativeActivity)
CacheMetadata(NativeActivityMetadata)

Creates and validates a description of the activity's arguments, variables, child activities, and activity delegates.

(Inherited from NativeActivity)
Cancel(NativeActivityContext)

When implemented in a derived class, runs logic to cause graceful early completion of the activity.

(Inherited from NativeActivity)
Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
Execute(NativeActivityContext)

When implemented in a derived class, runs the activity's execution logic.

(Inherited from NativeActivity)
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)
OnCreateDynamicUpdateMap(NativeActivityUpdateMapMetadata, Activity)

Raises an event when creating a map for the dynamic update.

(Inherited from NativeActivity)
OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity)

Raises an event when creating a map for the dynamic update.

(Inherited from NativeActivity)
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)
UpdateInstance(NativeActivityUpdateContext)

Updates the instance of NativeActivity.

(Inherited from NativeActivity)
