c# - 从对话框中调用表单

Question

我有一个简单的表格，

 [Serializable]
class CreateNewLeadForm
{
    public string FirstName;
    public string LastName;
    public static IForm<CreateNewLeadForm> BuildForm()
    {

        return new FormBuilder<CreateNewLeadForm>()
            .Message("Lets create a New Lead")
            .Field(nameof(FirstName))
            .Field(nameof(LastName))
            .Build();

    }
};

还有一个简单的对话框，

public class GreetDialog : IDialog<object>
{        
    public async Task StartAsync(IDialogContext context)
    {

        context.Wait(MessageReceivedAsync);
    }
    public   async Task MessageReceivedAsync(IDialogContext context, IAwaitable<Message> argument)
    {
       context.Wait(MessageReceivedAsync);
    }  
}  

如何从主对话框本身调用 Initiate FormDialog？一般来说，我们如何在对话框中启动新对话框？

Answer 1

为了启动一个 FormDialog，你可以这样做:

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

context.Call<CreateNewLeadForm>(myform, FormCompleteCallback);

查看 PizzaBot举个例子。

要在 Dialog 中启动新对话，您可以执行以下操作:

• context.Call 传递新对话框的实例和完成回调(如在表单中)

• context.Forward，您可以在其中转发消息到子对话框

  context.Forward(new MyChildDialog(), ResumeAfterChildDialog, message, CancellationToken.None);
