C# SqlWorkflowInstanceStore.Promote方法代码示例

static void Main(string[] args)
{
    // Create service host.
    WorkflowServiceHost host = new WorkflowServiceHost(CountingWorkflow(), new Uri(hostBaseAddress));

    // Add service endpoint.
    host.AddServiceEndpoint("ICountingWorkflow", new BasicHttpBinding(), "");

    // Define SqlWorkflowInstanceStore and assign it to host.
    SqlWorkflowInstanceStoreBehavior store = new SqlWorkflowInstanceStoreBehavior(connectionString);
    List<XName> variantProperties = new List<XName>()
    {   
        xNS.GetName("Count")
    };
    store.Promote("CountStatus", variantProperties, null);

    host.Description.Behaviors.Add(store);

    host.WorkflowExtensions.Add<CounterStatus>(() => new CounterStatus());
    host.Open(); // This sample needs to be run with Admin privileges.
                 // Otherwise the channel listener is not allowed to open ports.
                 // See sample documentation for details.

    // Create a client that sends a message to create an instance of the workflow.
    ICountingWorkflow client = ChannelFactory<ICountingWorkflow>.CreateChannel(new BasicHttpBinding(), new EndpointAddress(hostBaseAddress));
    client.start();

    Console.WriteLine("(Press [Enter] at any time to terminate host)");
