Question

如何在Form中间调用对话框？我想打电话给位置对话框https://github.com/Microsoft/BotBuilder-Location以获取地址。感谢。

[Serializable]
public class IssueShares
{
    [Prompt("Please enter holder name:")]
    public string HolderName;
    [Prompt("Please enter holder address:")]
   **[Call(typeof(AddressDialog))]**
    public Address Address;

    [Prompt("Enter shares class:")]
    public string SharesClass { get; set; }
    [Prompt("How many shares your issue?")]
    [Describe("Number of shares")]
    public int NumberOfShares { get; set; }
}

[Serializable]
public class AddressDialog : IDialog<Address>
{
    public Task StartAsync(IDialogContext context)
    {
        context.Wait(MessageReceived);
        return Task.CompletedTask;
    }

    private async Task MessageReceived(IDialogContext context, IAwaitable<object> result)
    {
        // some logic
        context.Done(address);
    }
}

您期望基于属性声明的解决方案还是可接受的常规代码？

Microsoft提供了作为序列或堆栈调用的Dialog Chaining。

以下SO问题中的接受答案回答了我的问题。

Calling Forms from Dialogs

以下是该答案的代码摘录：

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

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