在.NET C#中编写对话流的实现webhook

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

public class MyBot : ActivityHandler
{
    protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
    {
        // 处理接收到的用户消息
        var userMessage = turnContext.Activity.Text;
        
        // 编写对话逻辑，根据用户消息生成相应的回复
        var replyText = "你发送了消息：" + userMessage;
        
        // 创建一个回复消息
        var reply = MessageFactory.Text(replyText);
        
        // 发送回复消息
        await turnContext.SendActivityAsync(reply, cancellationToken);
    }
}

using Microsoft.Bot.Builder.Integration.AspNet.Core;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Logging;

public class Program
{
    public static void Main(string[] args)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())

        var configuration = builder.Build();

        var loggerFactory = LoggerFactory.Create(builder =>
        {
            builder.AddConsole();
        });

        var adapter = new BotFrameworkHttpAdapter(configuration, loggerFactory);

        adapter.ProcessAsync(HttpContext.Request, HttpContext.Response, myBot).Wait();
    }
