引言

使用 Microsoft Worflow Fundation 的简单 ASP.NET 网站。参数 - 网页 - 工作流。

使用代码

在 Global.asax 中定义运行时

void Application_Start(object sender, EventArgs e)
    {
        // Code that runs on application startup

        System.Workflow.Runtime.WorkflowRuntime workflowRuntime = new System.Workflow.Runtime.WorkflowRuntime();
        System.Workflow.Runtime.Hosting.ManualWorkflowSchedulerService manualService = new System.Workflow.Runtime.Hosting.ManualWorkflowSchedulerService();



        workflowRuntime.AddService(manualService);

        workflowRuntime.StartRuntime();

        Application["WorkflowRuntime"] = workflowRuntime;

    }

    void Application_End(object sender, EventArgs e)
    {
        //  Code that runs on application shutdown
        System.Workflow.Runtime.WorkflowRuntime workflowRuntime = Application["WorkflowRuntime"] as System.Workflow.Runtime.WorkflowRuntime;
        workflowRuntime.StopRuntime();
    }

参数

        //Datos del Global.asax
        wr = Application["WorkflowRuntime"] as WorkflowRuntime;
        manualScheduler = wr.GetService(typeof(ManualWorkflowSchedulerService)) as ManualWorkflowSchedulerService;

        //parametros al workflow
        Dictionary<string, object> parameters = new Dictionary<string, object>();
        parameters.Add("Valor", Int32.Parse(this.valor.Text));


        //Eventos del WorkFlow
        wr.WorkflowCompleted += new EventHandler<WorkflowCompletedEventArgs>(wr_WorkflowCompleted);
        wr.WorkflowTerminated += new EventHandler<WorkflowTerminatedEventArgs>(wr_WorkflowTerminated);

        Type type = typeof(WorkflowLibrary1.Workflow1);
        WorkflowInstance wi = wr.CreateWorkflow(type, parameters);
        wi.Start();

        //Ejecutar workflow
        manualScheduler.RunWorkflow(wi.InstanceId);

工作流

namespace WorkflowLibrary1
{
    public sealed partial class Workflow1: SequentialWorkflowActivity
    {
        public Workflow1()
        {
            InitializeComponent();
        }

      private string m_Resultado="Rechazado";
      private int m_Valor;
      private DateTime m_FechaHora = DateTime.Now;

       public string Resultado
       {
           get { return m_Resultado; }
       }

       public int Valor
       {
           get { return m_Valor; }
           set { m_Valor = value; }
       }

       public DateTime FechaHora
       {
           get { return m_FechaHora; }
       }



        private void ExecuteCodeActivity1(object sender, EventArgs e)
        {
            if (m_Valor > 100)
            {
                m_Resultado = "Aceptado";
            }
        }


    }

}

工作流

在 ASP.net 中简单使用工作流。使用参数
