我們正試圖挽救一個簡單的序列化對象PrivateConversationData的Dialog，并從國家訪問中MessagesController出于某種原因，在我們Context.Done在對話框中執行之后，我們沒有取回存儲在狀態中的數據    public static async Task SetUserAsync<T>(IActivity activity, T botUser) where T : IBotUser    {        if (botUser != null)        {            using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container, activity.AsMessageActivity()))            {                var botDataStore = scope.Resolve<IBotDataStore<BotData>>();                var key = new AddressKey()                {                    BotId = activity.Recipient.Id,                    ChannelId = activity.ChannelId,                    UserId = activity.From.Id,                    ConversationId = activity.Conversation.Id,                    ServiceUrl = activity.ServiceUrl                };                var privateData = await botDataStore.LoadAsync(key, BotStoreType.BotPrivateConversationData, CancellationToken.None);                privateData.SetProperty<T>(Keys.CacheBotUserKey, botUser);                await botDataStore.SaveAsync(key, BotStoreType.BotPrivateConversationData, privateData, CancellationToken.None);                await botDataStore.FlushAsync(key, CancellationToken.None);            }        }    }對話框代碼很簡單    public override async Task ProcessMessageAsync(IDialogContext context, IAwaitable<IMessageActivity> result)    {        BotUser user = new BotUser { UserId = "user1" };        await StateHelper.SetUserAsync(context.Activity, user);        var userFromState = await StateHelper.GetUserAsync<BotUser>(context.Activity);        Debug.WriteLine("Within dialog (after set) >" + userFromState?.UserId);        context.Done<object>(null);    }在這種情況下，我們得到以下輸出Within dialog (after set) > user1 Within MC (end) >有什么問題嗎？
