1.创建c#控制台程序

注意

我创建的控制台程序目标框架为**.NET7**

2.Nuget安装Betalgo.OpenAI.GTP3 包

注意

3.以流式方式输出

  public class Program
    {
        protected static readonly string API_KEY = "输入你的APIKEY";
        protected static List<ChatMessage> s_chat_message = new List<ChatMessage>();
        static  void Main(string[] args)
        {
            Console.WriteLine("准备就绪");
            while(true)
            {
                string? prompt = Console.ReadLine();
                if(!string.IsNullOrEmpty(prompt))
                {
                    args = prompt.Split(' ');
                    switch(args[0])
