【deepseek实战】绿色好用，不断网

前言

最佳deepseek火热网络，我也开发一款windows的电脑端，接入了deepseek，基本是复刻了网页端，还加入一些特色功能。

助力国内AI，发出自己的热量

说一下开发过程和内容的使用吧。

[1.4 、消息类](#1.4 、消息类)

[1.5 、设置](#1.5 、设置)

三、运行图示

四、总结

五、下载

一、介绍

目标：个人桌面AI助手，避免与专属API冲突，因为官网一些原因断网，自己接入API，确保能上deepseek。
先上图，确定是否需要使用：
软件是免费的，自己用自己的key或者别人的key，没有key可以联系我

二、具体工作

1.1、引用

dotnet8.0

cs 复制代码

  <TargetFramework>net8.0-windows</TargetFramework>

PackageReference

cs 复制代码

    <PackageReference Include="Newtonsoft.Json" Version="13.0.3" />
    <PackageReference Include="System.Drawing.Common" Version="8.0.0" />
    <PackageReference Include="System.Speech" Version="8.0.0" />
    <PackageReference Include="Spire.Doc" Version="12.8.0" />

Newtonsoft.Json 编译和反编译API信息

System.Drawing 绘制库，画界面主要

System.Speech 语音接入

Spire.Doc 文档使用

这几个引用根据自己需要添加

1.2、主界面

信息处理，分为及时信息和二次信息处理，这样能对文本信息进行个人需要处理

cs 复制代码

private async Task<ChatMessage> StreamResponseAsync(string apiKey, List<ChatMessage> chatHistory, string language, CancellationToken cancellationToken)
{
    var deepseekService = new DeepseekService(currentUser, _printService);
    var messages = chatHistory.Select(m => new ChatMessage
    {
        Role = m.Role,
        MessageType = m.MessageType,
        Content = m.Content
    }).ToList();
    try
    {
        var typingDelay = TimeSpan.FromMilliseconds(50);
        var buffer = new StringBuilder();
        
        var responseMessage = new ChatMessage
        {
            Role = "assistant",
            MessageType = MessageType.Answer,
            Content = string.Empty,
            WrappedContent = string.Empty
        };
        // 创建响应消息但不立即添加到历史记录
        var responseIndex = _displayHistory .Count;

        // 实时处理流式响应 - deepseek输出开始
        var charCount = 0;
        var tempBuffer = new StringBuilder();
      
        await foreach (var chunk in deepseekService.StreamChatResponseAsync(apiKey, messages, language).WithCancellation(cancellationToken))
        {
            if (string.IsNullOrEmpty(chunk) || _isStopping || cancellationToken.IsCancellationRequested) 
            {
                // Immediately return if stopping
                return new ChatMessage
                {
                    Role = "assistant",
                    MessageType = MessageType.Answer,
                    Content = "对话已终止",
                    WrappedContent = "对话已终止"
                };
            }
            
            tempBuffer.Append(chunk);
            charCount += chunk.Length;
            // 每20个字符更新一次显示
            if (charCount >= 20)
            {
                buffer.Append(tempBuffer.ToString());
                tempBuffer.Clear();
                charCount = 0;
                await Dispatcher.InvokeAsync(() => {
                    responseMessage.Content = buffer.ToString();
                    responseMessage.WrappedContent = WrapText(responseMessage.Content+"\n回答完成1",
                        ChatHistoryRichTextBox?.ActualWidth - 20 ?? ChatMessage.DefaultBorderWidth);
                    
                    // 更新_curchat
                    _curchatMesg = responseMessage;
                    
                    // 只在第一次更新时添加消息
                    if (_displayHistory .Count == responseIndex) {
                        _displayHistory .Add(responseMessage);
                    } else {
                        _displayHistory [responseIndex] = responseMessage;
                    }
                    
                    UpdateChatHistoryDisplayList(_displayHistory);
                });          
                await Task.Delay(typingDelay);
            }
        }
        
        // 处理剩余不足20字符的内容
        if (tempBuffer.Length > 0)

    finally

            </Grid>
        </Grid>
    </Viewbox>
</Window>

1.4 、消息类

设计这个是为了对消息类对API的信息进行存入和处理

cs 复制代码

 public enum MessageType
 {
     Question,
     Answer
 }

 public class ChatMessage
 {
     public static double DefaultBorderWidth { get; set; } = 300;

     public string Role { get; set; }
     public string Content { get; set; }
     public string WrappedContent { get; set; }
     public double BorderWidth { get; set; } = DefaultBorderWidth;
     public Brush BackgroundColor { get; set; }
     public Brush TextColor { get; set; }
     public DateTime Timestamp { get; set; }    
     public MessageType MessageType { get; set; }

     public ChatMessage()
     {
         Role = string.Empty;
         Content = string.Empty;
         WrappedContent = string.Empty;
         Timestamp = DateTime.Now;
         BackgroundColor = Brushes.White;
         TextColor = Brushes.Black;
     }

     public ChatMessage(string content, string wrappedContent, double borderWidth) : this()
     {
         Content = content;
         WrappedContent = wrappedContent;
         BorderWidth = borderWidth;
     }
 }

1.5 、设置

API KEY这里是必须填写的，不填写是无法进行问题的回答

这里是代码

cs 复制代码

private void SaveButton_Click(object sender, RoutedEventArgs e)
{
    // 更新用户信息
    currentUser.Username = UsernameTextBox.Text;
    currentUser.Password = PasswordBox.Password;
    currentUser.AiUrl = AiUrlTextBox.Text;
    currentUser.ModelUrl = ModelUrlTextBox.Text;
    currentUser.ApiKey = ApiKeyTextBox.Text == "请输入deepseek的API keys" ? 
        string.Empty : ApiKeyTextBox.Text;

    // 保存语言设置
    var selectedLanguage = ((ComboBoxItem)LanguageComboBox.SelectedItem).Content.ToString();
    string languageCode = selectedLanguage == "中文" ? "zh-CN" : "en-US";
    AppSettings.Instance.DefaultLanguage = languageCode;
    AppSettings.Instance.SaveLanguageSettings(languageCode);

    // 保存复制选项设置
    //AppSettings.Instance.CopyCurrent = CopyCurrentRadio.IsChecked == true;
    AppSettings.Instance.Save();

    // 保存到配置文件
    string configPath = System.IO.Path.Combine(
        Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData),
        "AIzhushou",
        "config.json");
    
    // 确保目录存在
    var directoryPath = System.IO.Path.GetDirectoryName(configPath);
    if (string.IsNullOrEmpty(directoryPath))
    {
        throw new InvalidOperationException("无法确定配置文件的目录路径");
    }
    System.IO.Directory.CreateDirectory(directoryPath);
    
    // 序列化保存
    string json = Newtonsoft.Json.JsonConvert.SerializeObject(currentUser);
    System.IO.File.WriteAllText(configPath, json);
    
    MessageBox.Show("设置保存成功", "提示", MessageBoxButton.OK, MessageBoxImage.Information);
    this.Close();
}

三、运行图示

四、总结

实测了windows c#版本和python版本， c#版比python版本的性能更好，可能C#是微软亲儿子原因？
一定用要异步处理，没有什么特别需要
AI里面，deepseek是真的强
如果需要提供协助，可以私信我

写着写着就这么多了，可能不是特别全，不介意费时就看看吧。有时间还会接着更新。
