發送Hero卡列表以附加到Bot框架中

Question

我想向英雄卡中的特定醫生顯示Sessions並將其發送到機器人。

這裏是代碼

private async Task ShowSessionsHeroCard(IDialogContext context) 
    { 
     var replyToConversation = context.MakeMessage(); 
     replyToConversation.AttachmentLayout = AttachmentLayoutTypes.Carousel; 
     replyToConversation.Attachments = GetSessionHeroCard(); 
     await context.PostAsync(replyToConversation); 
    } 

private Attachment GetSessionHeroCard() 
    { 
     var heroCard = new HeroCard(); 
     foreach (var sessionDetails in scheduleList) 
     { 
      string[] session = GetSplittedDetails(sessionDetails); 

      string hospitalName = session[0]; //Hospital Name: {0} 
      string availableDay = session[1]; //Available Day: {1} 
      string appointmentNo = session[2]; // Appoinment No: {2} 
      string sessionAvailable = session[3]; // Session: {3} 

      heroCard.Title = hospitalName; 
      heroCard.Subtitle = availableDay; 
      heroCard.Text = sessionAvailable + appointmentNo; 
     } 
     return heroCard.ToAttachment(); 
    } 


private string[] GetSplittedDetails(string sessionDetails) 
    { 
     return sessionDetails.Split(','); 
    } 

當我做replyToConversation.Attachments = GetSessionHeroCard（）;

我收到以下錯誤

Cannot implicitly convert type 'Microsoft.Bot.Connector.Attachment' to 'System.Collections.Generic.List<Microsoft.Bot.Connector.Attachment>' 

請幫助我。我掙扎了幾個小時。在此先感謝:)

Attachments屬性是List<Attachment>這就是爲什麼你看到該錯誤，你正試圖分配一個附件的列表。

你可以這樣做：

replyToConversation.Attachments = new List<Attachment>(); 
replyToConversation.Attachments.Add(GetSessionHeroCard());
