WorkflowRuntime.WorkflowLoaded Event

Occurs when the workflow instance is loaded into memory.

Namespace:  System.Workflow.Runtime
Assembly:  System.Workflow.Runtime (in System.Workflow.Runtime.dll)

public event EventHandler<WorkflowEventArgs> WorkflowLoaded

WorkflowLoaded occurs after the persistence service has restored the workflow instance, but before the workflow runtime engine begins to execute any activities.

For the WorkflowLoaded event, sender will contain the WorkflowRuntime and WorkflowEventArgs will contain the WorkflowInstance associated with the event.

For more information about handling events, see Consuming Events.

The following code example demonstrates how you can use WorkflowRuntime functionality from a workflow host. The code associates the WorkflowLoaded with an event handler, a method named OnWorkflowLoad.

This code example is part of the Custom Persistence Service SDK sample from the Program.cs file. For more information, see Custom Persistence Service.

static void Main()
{
    using (WorkflowRuntime workflowRuntime = new WorkflowRuntime())
    {
        try
        {
            // engine will unload workflow instance when it is idle
            workflowRuntime.AddService(new FilePersistenceService(true));

            workflowRuntime.WorkflowCreated += OnWorkflowCreated;
            workflowRuntime.WorkflowCompleted += OnWorkflowCompleted;
            workflowRuntime.WorkflowIdled += OnWorkflowIdle;
            workflowRuntime.WorkflowUnloaded += OnWorkflowUnload;
            workflowRuntime.WorkflowLoaded += OnWorkflowLoad;
            workflowRuntime.WorkflowTerminated += OnWorkflowTerminated;
            workflowRuntime.ServicesExceptionNotHandled += OnExceptionNotHandled;

            workflowRuntime.CreateWorkflow(typeof(PersistenceServiceWorkflow)).Start();

            waitHandle.WaitOne();
        }
        catch (Exception e)
        {
            Console.WriteLine("Exception \n\t Source: {0} \n\t Message: {1}", e.Source, e.Message);
        }
        finally
        {
            workflowRuntime.StopRuntime();
            Console.WriteLine("Workflow runtime stopped, program exiting... \n");
        }
    }
}
