如何正确地将参数添加到工作流程中？

Question

我正在尝试将一个简单的参数添加到我的一个活动中，该参数是序列中的openbrowser，之后，我创建了一个具有该序列的简单工作流，然后我运行它。

尽管变量已添加到序列中，但字典是正确创建的，并且正确命名的变量以及传递到工作流的字典，但它仍然使我在帖子底部的错误。

我一直在尝试弄清楚几天，但没有成功，应该如何写这件事？

    private void Button_Click(object sender, RoutedEventArgs e)
    {

        Variable<String> myVariable = new Variable<string>(Name = "Hehe");

        Dictionary<string, object> mainInputs = new Dictionary<string, object>();
        mainInputs.Add("Hehe","www.youtube.com");

        OpenBrowser samsungPortalBrowser = new OpenBrowser();
        samsungPortalBrowser.NewSession = true;
        samsungPortalBrowser.BrowserType = BrowserType.Chrome;
        samsungPortalBrowser.Url = myVariable;

        Sequence createSequence = new Sequence();
        createSequence.Activities.Add(samsungPortalBrowser);
        createSequence.Variables.Add(myVariable);
        WorkflowApplication app = new WorkflowApplication(createSequence, mainInputs);

        app.Run();


    }



System.ArgumentException: 'The values provided for the root activity's arguments did not satisfy the root activity's requirements:
'Sequence': The following keys from the input dictionary do not map to arguments and must be removed: Hehe.  Please note that argument names are case sensitive.
Parameter name: rootArgumentValues'

无需发表评论，请自己尝试剪！

internal class Program
{
static void Main(string args)
{
IDictionary<string, object> input = new Dictionary<string, object>();
input.Add(“inMSG”, “www.youtube.com”);
//input.Add(“myBrowser”, null);

        IDictionary<string, object> output = new Dictionary<string, object>();

        MyCodeWorkflow activity = new MyCodeWorkflow();
        output = WorkflowInvoker.Invoke(activity, input);
        //wtf
    }

    public class MyCodeWorkflow : Activity
    {
        public InArgument<String> inMSG { get; set; }
        public OutArgument<String> outMSG { get; set; }

        public OutArgument<Browser> myBrowser { get; set; }

        public MyCodeWorkflow()
        {
            this.Implementation = () => new Sequence
            {
                Activities =
                {
                    new OpenBrowser()
                    {
                        BrowserType = BrowserType.Chrome,
                        NewSession = true,
                        Url = new InArgument<string>((activityContext)=>this.inMSG.Get(activityContext)),
                        UiBrowser = new OutArgument<Browser>((ActivityContext)=> this.myBrowser.Get(ActivityContext))
                    },

                    new Assign<String>
                    {
                        To=new ArgumentReference<String>("outMSG"),
                        Value=new InArgument<String>((activityContext)=>this.inMSG.Get(activityContext))
                    }
                }
            };
        }
    }
}
