编写AI类

代码中apikey需要用你自己的

csharp 复制代码

using Microsoft.SemanticKernel.ChatCompletion;
using Microsoft.SemanticKernel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace WpfApp1
{
    /// <summary>
    /// ai 类
    /// </summary>
    public class AI
    {
        public AI()
        {
            IKernelBuilder kernelBuilder = Kernel.CreateBuilder();
#pragma warning disable SKEXP0010
            kernelBuilder.AddOpenAIChatCompletion("deepseek-v3", new Uri("https://dashscope.aliyuncs.com/compatible-mode/v1"), "apikey");//阿里平台
            Kernel = kernelBuilder.Build();
            ChatHistory = new ChatHistory();
            ChatHistory.AddSystemMessage("你是一个乐于解答各种问题的助手，你的任务是为用户提供专业、准确、有见地的建议。");
        }
        public Kernel Kernel { get; set; }

        /// <summary>
        /// 聊天记录
        /// </summary>
        public ChatHistory ChatHistory { get; set; }

        /// <summary>
        /// 向AI提问
        /// </summary>
        /// <param name="questions">问题</param>
        /// <param name="action">字符流回调函数（委托中string代表的是AI回答的字符）</param>

        {
            ChatHistory.AddUserMessage(questions);
            return await AskAIQuestions(ChatHistory, action);
        }

        {
            //task.Result可以拿值
            var chatService = Kernel.GetRequiredService<IChatCompletionService>();
            string msg = "";
            await foreach (StreamingChatMessageContent chatUpdate in chatService.GetStreamingChatMessageContentsAsync(chatHistory))
            {
                if (chatUpdate.Content is { Length: > 0 })
                {
                    msg += chatUpdate.Content;
                    action(chatUpdate.Content);
                    Thread.Sleep(10);
                }
            }
            return msg;
        }
    }
}
