我有一个需要重置或杀死（使用context.Done）当前的IDialogContext实例，并创建一个新的实例，并在不同的功能中使用它。我如何创建这样一个实例，IDialogContext是一个接口。可能吗？如何在Microsoft Bot框架中创建一个新的IDialogContext实例？
这是从我试图调用一个函数 “selfredirect”
private async Task ApprovalConfirm(IDialogContext context, IAwaitable<IMessageActivity> result)
{
var message = await result;
xxxticket xxxticketobject = new xxxticket();
if (message.Text.Contains("yes"))
{
xxxticketobject = context.ConversationData.Get<xxxticket>("xxxcard");
if (xxxticketobject.action == "Approve")
await context.PostAsync("Accepted");
else
await context.PostAsync("Rejected");
context.ConversationData.RemoveValue("xxxfinalcard");
context.Reset();// *This is what I want to do...clear context and then call the following function*
await SelfRedirect(context, context.UserData.Get<string>("CurrentQuery"), "Approval");
}
else if (message.Text == "no")
{
await context.PostAsync("Thank you");
context.Done(context);
}
else
await SelfRedirect(context, context.UserData.Get<string>("CurrentQuery"), null);
}
的selfredirect功能
public static async Task SelfRedirect(IDialogContext context, string msg, string intent=null)
{
try
{
DialogLuis LUISDialog = new DialogLuis();
IMessageActivity message = context.MakeMessage();
message.Text = msg;
var tasks = LUISDialog.services.Select(s => s.QueryAsync(message.Text, context.CancellationToken)).ToArray();
var results = await Task.WhenAll(tasks);
var winners = from result in results.Select((value, index) => new { value, index })
let resultWinner = LUISDialog.BestIntentFrom(result.value)
where resultWinner != null
select new LuisServiceResult(result.value, resultWinner, LUISDialog.services[result.index]);
if (intent != null)
{
winners = from result in results.Select((value, index) => new { value, index })
let resultWinner = new IntentRecommendation(intent)
where resultWinner != null
select new LuisServiceResult(result.value, resultWinner, LUISDialog.services[result.index]);
}
var winner = LUISDialog.BestResultFrom(winners);
if (winner == null)
{
throw new InvalidOperationException("No winning intent selected from Luis results.");
}
if (winner.Result.Dialog?.Status == DialogResponse.DialogStatus.Question)
{
var childDialog = await LUISDialog.MakeLuisActionDialog(winner.LuisService,
winner.Result.Dialog.ContextId,
winner.Result.Dialog.Prompt);
context.Call(childDialog, LUISDialog.LuisActionDialogFinished);
}
else
{
IAwaitable<IMessageActivity> item = null;
await LUISDialog.DispatchToIntentHandler(context, item, winner.BestIntent, winner.Result);
}
}
catch (Exception ex) { CommonMethods.LogTime("", ex, context); }
}
的功能，但我不能用当堆栈为空时，重置后的重定向功能。请帮助
让我解释我为什么通过这个小小的功能
private async Task ApprovalConfirm(IDialogContext context, IAwaitable<IMessageActivity> result)
{
var message = await result;
if (message.Text == "no")
{
await context.PostAsync("Thank you");
context.Done(context);
}
else if (message.Text == "yes")
{
await context.PostAsync("yes");
context.Done(context);
}
else
{
context.Wait(MessageReceived);
}
}
我的使用情况是喜欢用selfredirect函数而不是context.wait（的messageReceived），如果用户类型是那么机器人应返回yes，如果用户输入no，那么bot应该返回谢谢。并且如果用户键入“Hi”，机器人应该通过路易斯找到Hi的答案，这将打到新的问候意图并返回Hi用户。
在这里，如果我的用户context.Wait（的messageReceived），那么机器人将只需等待下一个查询从用户
对话框的结构！
[LuisIntent("Approval")]
public async Task Approval(IDialogContext context, LuisResult result)
{
context.ConversationData.SetValue("currentIntent", "Approval");
.
.
.
PromptDialog.Choice<string>(context, ApprovalList, ...);
}
private async Task ApprovalList(IDialogContext context, IAwaitable<string> result)
{
try
{
var request_type = await result;
.
.
context.Wait(ApprovalResponse);
}
}
catch (Exception ex)
{
CommonMethods.LogTime("ApprovalList", ex, context);
}
}
private async Task ApprovalResponse(IDialogContext context, IAwaitable<IMessageActivity> result)
{
var message = await result;
.
.
.
context.Wait(AfterApprovalComment);
}
catch (Exception ex)
{
CommonMethods.LogTime("ApprovalResponse", ex, context);
await context.PostAsync("out of approvals...");
context.Done(context);
}
}
private async Task ApprovalConfirm(IDialogContext context, IAwaitable<IMessageActivity> result)
{
var message = await result;
.
.
.
await SelfRedirect(context, context.UserData.Get<string>("CurrentQuery"), "Approval");
}
我想要在当前函数中创建的实例。因为我正在处理多个对话框，最后我需要将它重定向到一个不同的函数，该函数也需要一个Idialogcontext实例 –
请显示您的代码，否则很难理解您要做什么。 –
@EzequielJadib嗨我已经添加了代码.. :) –
