When the workflow completes, the workflow runtime engine raises the WorkflowCompleted event. The workflow runtime engine passes all of the output parameters of the workflow in a WorkflowCompletedEventArgs. These include the out and ref parameters of the workflow.

The following code example demonstrates an event handler method that takes WorkflowCompletedEventArgs as a parameter. The OnWorkflowCompleted method is called when the WorkflowCompleted event is raised. The code uses the OutputParameters property to obtain the value associated with the Status key and writes it to the console.

This code example is part of the Sequential Workflow with Parameters SDK Sample from the Program.cs file. For more information, see Sequential Workflow With Parameters.

Shared Sub OnWorkflowCompleted(ByVal sender As Object, ByVal e As WorkflowCompletedEventArgs)

    'The order status is stored in the "status" "out" parameter
    Dim orderStatus As String = e.OutputParameters("Status").ToString()
    Console.WriteLine("Order was " + orderStatus)
    waitHandle.Set()
End Sub

static void OnWorkflowCompleted(object sender, WorkflowCompletedEventArgs e)
{
    //The order status is stored in the "status" "out" parameter
    string orderStatus = e.OutputParameters["Status"].ToString();
    Console.WriteLine("Order was " + orderStatus);
    waitHandle.Set();
}
