Question

我正在使用FormFlow。当机器人完成所有问题并调用processOrder时，我想继续对话，但我不知道应该在哪里调用另一种方法：

 OnCompletionAsyncDelegate<Form> processOrder = async (context, state) =>
        {
            await context.PostAsync("You done");
              // context.Call(OnFormComplete);
        };

当我尝试这样打电话时，我收到了这条消息：

错误CS7036没有给出对应于'IDialogStack.Call（IDialog，ResumeAfter）'Project1 C：\ Projects \ Good Version \ v-17.2.2017 \ demo-Project1 \的所需形式参数'resume'的参数Project1 \ Dialogs \ Form.cs 34编译器IntelliSense活动编译器

我在rootdialog.cs中以这种模式调用表单流：

 var myform = new FormDialog<Form>(new Form(), Form.BuildForm, FormOptions.PromptInStart, null);

                context.Call(myform, ResumeAfterOptionDialog);

Formbuilder是：

return new FormBuilder<Form>()
            .Field(nameof(Time))
            .Field(nameof(Number1))
            .Field(nameof(Number2))
            .AddRemainingFields()

             .Confirm("Would you like to process")
              .OnCompletion(processOrder)
            .Build();

我想继续对话，因为机器人停了下来。我怎么称呼另一种方法，我应该在哪里打电话？

你将在formFlow类中使用类似的东西：

[Serializable]
public class CustomFormDialog
{
    public DateTime Time { get; set; }
    public int Number1 { get; set; }
    public int Number2 { get; set; }

    public static IForm<CustomFormDialog> Build()
    {
        OnCompletionAsyncDelegate<CustomFormDialog> processOrder = async (context, state) =>
        {
            await context.Forward(new OtherFormDialog(state), onOtherFormProcessed, state, CancellationToken.None);
        };

        return new FormBuilder<CustomFormDialog>()
            .Field(nameof(Time))
            .Field(nameof(Number1))
            .Field(nameof(Number2))
            .AddRemainingFields()

            .Confirm("Would you like to process?")
            .OnCompletion(processOrder)
            .Build();
    }

    private static async Task onOtherFormProcessed(IDialogContext context, IAwaitable<CustomFormDialog> result)
    {
        var formValue = await result;

        await context.PostAsync($"You are again in the form: Time: {formValue.Time}, Number1: {formValue.Number1}, Number2: {formValue.Number2}");
    }
}

我定义了一个虚拟对话框，它接收formFlow对话框的响应，并执行一些操作并调用该对话框的完成并返回到FormFlow类：

public class OtherFormDialog : IDialog<CustomFormDialog>
{
    private readonly CustomFormDialog formData;

    public OtherFormDialog(CustomFormDialog prevState)
    {
        this.formData = prevState;
    }

    public async Task StartAsync(IDialogContext context)
    {
        //Here, we can do anything
        await context.PostAsync("I'll check your data. Please wait!");

        await context.PostAsync("Just joking! No validation at all.");
        context.Done(this.formData);
    }
}

如何在使用FormFlow在chatbot中完成processOrder后调用另一个方法？
