仿Manus一

1. 1.会话管理核心类

csharp复制
public class SessionManager
{
    private string _currentSessionId;
    private readonly string _workspacePath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "todu");
    
    public void InitWorkspace()
    {
        if (!Directory.Exists(_workspacePath))
            Directory.CreateDirectory(_workspacePath);
    }
    
    public string CreateNewSession()
    {
        var sessionId = Guid.NewGuid().ToString("N");
        File.WriteAllText(GetSessionFilePath(sessionId), "[]");
        return sessionId;
    }
    
    public void SwitchSession(string sessionId)
    {
        _currentSessionId = sessionId;
        if (!File.Exists(GetSessionFilePath(sessionId)))
            throw new FileNotFoundException("Session file missing");
    }
    
    public List<TodoItem> GetCurrentTodos()
    {
        return JsonConvert.DeserializeObject<List<TodoItem>>(
            File.ReadAllText(GetSessionFilePath(_currentSessionId))
        );
    }
    
    private string GetSessionFilePath(string sessionId) 
        => Path.Combine(_workspacePath, $"{sessionId}.json");
}

2.API通信处理类

csharp复制
public class TodoApiClient
{
    private const string ApiEndpoint = "https://api.siliconflow.cn/v1/chat/completions";
    
    public async Task<List<TodoItem>> GenerateTodosAsync(string question)
    {
        using var client = new HttpClient();
        client.DefaultRequestHeaders.Authorization = 
            new AuthenticationHeaderValue("Bearer", "[YOUR_API_KEY]");

        var request = new
        {
            model = "deepseek-ai/DeepSeek-V3",
            messages = new[] {
                new { 
                    role = "user", 
                    content = $"请根据以下问题生成规范的待办事项列表：{question}。按JSON数组格式返回" 
                }
            },
            response_format = new { type = "json_object" }
        };

        var response = await client.PostAsync(ApiEndpoint, 
            new StringContent(JsonConvert.SerializeObject(request), Encoding.UTF8, "application/json"));

        var responseObj = JObject.Parse(await response.Content.ReadAsStringAsync());
        return ParseTodoJson(responseObj["choices"][0]["message"]["content"].ToString());
    }

    private List<TodoItem> ParseTodoJson(string json)
    {
        // 示例响应格式：{ "todos": [{...}] }
        return JObject.Parse(json)["todos"]?
            .Select(t => new TodoItem {
                Id = Guid.NewGuid(),
                Content = t["content"].ToString(),
                Created = DateTime.Now
            }).ToList() ?? new List<TodoItem>();
    }
}

3.文件存储服务

csharp复制
public class TodoFileManager
{
    private FileSystemWatcher _watcher;
    
    public void SetupFileWatcher(Action<string> onChange)
    {
        _watcher = new FileSystemWatcher
        {
            Path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "todu"),
            Filter = "*.json",
            NotifyFilter = NotifyFilters.LastWrite
        };
        
        _watcher.Changed += (s, e) => onChange(e.Name.Replace(".json", ""));
        _watcher.EnableRaisingEvents = true;
    }

    public void SaveTodos(string sessionId, List<TodoItem> todos)
    {
        var json = JsonConvert.SerializeObject(todos, Formatting.Indented);
        File.WriteAllText(GetFilePath(sessionId), json, Encoding.UTF8);
    }

    private string GetFilePath(string sessionId) 
        => Path.Combine("todu", $"{sessionId}.json");
}

4.窗口界面关键代码（Windows Forms）

csharp复制
public partial class MainForm : Form
{
    private SessionManager _sessionManager = new SessionManager();
    private TodoApiClient _apiClient = new TodoApiClient();
    private BindingList<TodoItem> _currentTodos = new BindingList<TodoItem>();
    
    public MainForm()
    {
        InitializeComponent();
        _sessionManager.InitWorkspace();
        
        lstSessions.DisplayMember = "Key";
        lstSessions.ValueMember = "Value";
        
        todoListBox.DataSource = _currentTodos;
        todoListBox.DisplayMember = "Content";
    }

    // 新建会话按钮
    private void btnNewSession_Click(object sender, EventArgs e)
    {
        var sessionId = _sessionManager.CreateNewSession();
        lstSessions.Items.Add(new KeyValuePair<string, string>($"会话 {lstSessions.Items.Count+1}", sessionId));
    }

    // 发送提问按钮
    private async void btnSend_Click(object sender, EventArgs e)
    {
        var todos = await _apiClient.GenerateTodosAsync(txtInput.Text);
        
        _currentTodos.Clear();
        foreach(var item in todos)
            _currentTodos.Add(item);
        
        _sessionManager.SaveCurrentTodos(_currentTodos.ToList());
    }

    // 切换会话选择
    private void lstSessions_SelectedIndexChanged(object sender, EventArgs e)
    {
        if(lstSessions.SelectedItem is KeyValuePair<string, string> selected)
        {
            _sessionManager.SwitchSession(selected.Value);
            _currentTodos = new BindingList<TodoItem>(_sessionManager.GetCurrentTodos());
            todoListBox.DataSource = _currentTodos;
        }
    }
}

5.扩展功能建议

csharp复制
// 增加会话元数据存储
public class SessionMetadata
{
    public string SessionId { get; set; }
    public string Title { get; set; }
    public DateTime LastModified { get; set; }
}

// 在SessionManager中添加
public void SaveSessionMetadata(SessionMetadata meta)
{
    var path = Path.Combine(_workspacePath, "_sessions.json");
    var list = File.Exists(path) ? 
        JsonConvert.DeserializeObject<List<SessionMetadata>>(File.ReadAllText(path)) 
        : new List<SessionMetadata>();
    
    if(list.Any(m => m.SessionId == meta.SessionId))
        list.RemoveAll(m => m.SessionId == meta.SessionId);
    
    list.Add(meta);
    File.WriteAllText(path, JsonConvert.SerializeObject(list));
}

csharp复制
public class TodoItem
{
    public Guid Id { get; set; }
    public string Content { get; set; }
    public bool IsCompleted { get; set; }
    public DateTime Created { get; set; }
    public DateTime? CompletedDate { get; set; }
}

// 在界面中添加状态切换
private void todoListBox_MouseDoubleClick(object sender, MouseEventArgs e)
{
    if(todoListBox.SelectedItem is TodoItem item)
    {
        item.IsCompleted = !item.IsCompleted;
        item.CompletedDate = item.IsCompleted ? DateTime.Now : null;
        _sessionManager.SaveCurrentTodos(_currentTodos.ToList());
        todoListBox.Refresh();
    }
}
