Windows 워크 플로 기반 ASP.NET 사용하기

Question

Windows 워크 플로 기반으로 asp.net 웹 응용 프로그램을 구축하려고합니다.

내가 찾은 유용한 사이트가 좋아 :

워크 플로는 내가 ASP를 생성

<Activity mc:Ignorable="sap" x:Class="ApproachWithWorkflows.WriteLineActivity" sap:VirtualizedContainerService.HintSize="654,676" mva:VisualBasic.Settings="Assembly references and imported namespaces for internal implementation" xmlns="http://schemas.microsoft.com/netfx/2009/xaml/activities" xmlns:av="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:mv="clr-namespace:Microsoft.VisualBasic;assembly=System" xmlns:mva="clr-namespace:Microsoft.VisualBasic.Activities;assembly=System.Activities" xmlns:s="clr-namespace:System;assembly=mscorlib" xmlns:s1="clr-namespace:System;assembly=System" xmlns:s2="clr-namespace:System;assembly=System.Xml" xmlns:s3="clr-namespace:System;assembly=System.Core" xmlns:sad="clr-namespace:System.Activities.Debugger;assembly=System.Activities" xmlns:sap="http://schemas.microsoft.com/netfx/2009/xaml/activities/presentation" xmlns:scg="clr-namespace:System.Collections.Generic;assembly=System" xmlns:scg1="clr-namespace:System.Collections.Generic;assembly=System.ServiceModel" xmlns:scg2="clr-namespace:System.Collections.Generic;assembly=System.Core" xmlns:scg3="clr-namespace:System.Collections.Generic;assembly=mscorlib" xmlns:sd="clr-namespace:System.Data;assembly=System.Data" xmlns:sl="clr-namespace:System.Linq;assembly=System.Core" xmlns:st="clr-namespace:System.Text;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> 
<Flowchart sad:XamlDebuggerXmlReader.FileName="C:\Documents and Settings\hauke\Desktop\Uni\Masterarbeit SVN SE\Software\Workflowansatz\ApproachWithWorkflows\ApproachWithWorkflows\WriteLineActivity.xaml" sap:VirtualizedContainerService.HintSize="614,636">

    </scg3:Dictionary> 
    </sap:WorkflowViewStateService.ViewState> 
    <WriteLine sap:VirtualizedContainerService.HintSize="211,59" Text="worked.." /> 
</FlowStep> 

액티비티입니다 간단한 버튼 .NET 프로젝트 : 뒤에 코드에서

<asp:Button Text="Purchase" ID="Label1" runat="server" OnClick="btnClick" /> 

, 나는 워크 플로우를 호출하려고 (그리고 위해 Application_Start로의 Global.asax에서 WorkflowRuntime 초기화) : 지금

WorkflowRuntime workflowRuntime = Application["WorkflowRuntime"] as WorkflowRuntime; 
ManualWorkflowSchedulerService manualScheduler = 
    workflowRuntime.GetService(typeof(ManualWorkflowSchedulerService)) 
    as ManualWorkflowSchedulerService; 

WorkflowInstance instance = workflowRuntime.CreateWorkflow(
    typeof(ApproachWithWorkflows.WriteLineActivity)); 
instance.Start(); 
manualScheduler.RunWorkflow(instance.InstanceId); 

I을 응용 프로그램을 실행하고 버튼을 누르면 CreateWorkflow에 "입력 워크 플로 유형이 Activity 여야합니다. \ r \ n 매개 변수 이름 : workflowType"과 같은 오류가 나타납니다.

하지만 활동은 활동입니다! 내가 도대체 ​​뭘 잘못하고있는 겁니까?

Answer 1

WF 4.0 런타임을 실행하기 위해 WF 3.5 런타임 클래스를 사용하는 것 같습니다. WorkflowInvoker 또는 WorkflowApplication을 살펴보십시오.
