在Microsoft BOT框架中添加两条消息之间的延迟

using Microsoft.Bot.Builder;
using Microsoft.Bot.Schema;
using System.Threading.Tasks;

public class DelayBot : IBot
{
    public async Task OnTurnAsync(ITurnContext turnContext)
    {
        if (turnContext.Activity.Type == ActivityTypes.Message)
        {
            await turnContext.SendActivityAsync("第一条消息");

            // 添加延迟
            await Task.Delay(5000); // 延迟5秒

            await turnContext.SendActivityAsync("第二条消息");
        }
    }
}
