c# - Azure Bot Framework FormFlow 复杂表单

Question

我正在尝试使用 Azure 机器人框架创建一个机器人，该机器人将请求未知数量的复杂对象(每个对象需要三个响应)。但我不知道如何为根表单中的每个复杂对象创建表单。请参阅http://docs.botframework.com/sdkreference/csharp/forms.html 。它指出: “为了处理一系列复杂对象，您需要为顶级 C# 类创建一个表单，并为复杂对象创建一个表单。您可以使用对话框系统将表单组合在一起。”这就是我不知道该怎么做。

public enum SystemSelection { SharePoint, BizTalk, Azure, Office365 };

public enum RequestType { Bug, SupportRequest, Question };

public enum Importance { Blocking, High, Medium, Low };

[Serializable]
class Declaration
{
    public string Type;
    public string Amount;
    public string Date;

    public static IForm<Declaration> BuildForm()
    {
        return new FormBuilder<Declaration>()
                .Message("Add a declaration")
                .Build();
    }
}

[Serializable]
class SupportRequest
{

    public SystemSelection? SystemSelection;
    public RequestType? RequestType;
    public Importance? Importance;

    public List<Declaration> Declarations;

    public static IForm<SupportRequest> BuildForm()
    {
        IForm<Declaration> aForm = new FormBuilder<Declaration>().Message("Add declaration").Build();

        // now what?

        return new FormBuilder<SupportRequest>()
                .Message("Welcome to the simple support bot!")
                .Build();
    }
}

Controller :

  [BotAuthentication]
  public class MessagesController : ApiController
{
    internal static IDialog<SupportRequest> MakeRootDialog()
    {
        // change something here??
        return Chain.From(() => FormDialog.FromForm(SupportRequest.BuildForm));
    }

    public async Task<Message> Post([FromBody]Message message)
    {
        if (message.Type == "Message")
        {
            return await Conversation.SendAsync(message, MakeRootDialog);
        }
        else
        {
            return HandleSystemMessage(message);
        }
    }

您可以使用 Chain 类中的方法来编写对话框。由于这些方法也支持 LINQ 语法，因此您可以在 MakeRootDialog 中编写类似的内容来依次执行 SupportRequest 对话框和 Decalaration 对话框:

    internal static IDialog<SupportRequest> MakeRootDialog()
    {
        var dlg = from x in FormDialog.FromForm(SupportRequest.BuildForm)
                  from y in FormDialog.FromForm(Declaration.BuildForm)
                  select x;
        return dlg;
        // return Chain.From(() => FormDialog.FromForm(SupportRequest.BuildForm));
    }

您还可以像这样手动链接对话框:

        var dlg = Chain.From(() => FormDialog.FromForm(SupportRequest.BuildForm))
            .ContinueWith<SupportRequest,Declaration>(async (ctx, sr) =>
            {
                var res = await sr;
                return FormDialog.FromForm(Declaration.BuildForm);
            });
