Load(WorkflowApplicationInstance)

Loads a workflow instance from an instance store with specified instance.

public:
 void Load(System::Activities::WorkflowApplicationInstance ^ instance);

public void Load (System.Activities.WorkflowApplicationInstance instance);

member this.Load : System.Activities.WorkflowApplicationInstance -> unit

Public Sub Load (instance As WorkflowApplicationInstance)

Parameters

instance

WorkflowApplicationInstance

The instance.

Load(Guid)

Loads the specified workflow instance into memory from an instance store.

public:
 void Load(Guid instanceId);

public void Load (Guid instanceId);

member this.Load : Guid -> unit

Public Sub Load (instanceId As Guid)

Parameters

instanceId

Guid

A globally unique 128-bit identifier for the workflow instance.

Examples

The following example calls Load to load persisted workflow instance from a SqlWorkflowInstanceStore.

string input = Console.ReadLine();

WorkflowApplication application = new WorkflowApplication(activity);
application.InstanceStore = instanceStore;

application.Completed = (workflowApplicationCompletedEventArgs) =>
{
    Console.WriteLine("\nWorkflowApplication has Completed in the {0} state.", workflowApplicationCompletedEventArgs.CompletionState);
};

application.Unloaded = (workflowApplicationEventArgs) =>
{
    Console.WriteLine("WorkflowApplication has Unloaded\n");
    instanceUnloaded.Set();
};

application.Load(id);

//this resumes the bookmark setup by readline
application.ResumeBookmark(readLineBookmark, input);

instanceUnloaded.WaitOne();

Load(WorkflowApplicationInstance, DynamicUpdateMap)

member this.Load : System.Activities.WorkflowApplicationInstance * TimeSpan -> unit

Public Sub Load (instance As WorkflowApplicationInstance, timeout As TimeSpan)

Parameters

instance

WorkflowApplicationInstance

The instance.

timeout

TimeSpan

Parameters

instanceId

Guid

A globally unique 128-bit identifier for the workflow instance.

timeout

TimeSpan

The interval in which the load operation must complete before the load operation is canceled and a TimeoutException is thrown.
