如何处理保存事件- C#

public delegate void SaveEventHandler(object sender, EventArgs e);

public class SaveEventArgs : EventArgs
{
    // 可以在这里添加自定义的保存事件参数
}

public class SaveManager
{
    public event SaveEventHandler SaveEvent;

    public void Save()
    {
        // 执行保存操作

        // 触发保存事件
        OnSaveEvent();
    }

    protected virtual void OnSaveEvent()
    {
        SaveEvent?.Invoke(this, new SaveEventArgs());
    }
}

public class MyClass
{
    private SaveManager saveManager;

    public MyClass()
    {
        saveManager = new SaveManager();
        saveManager.SaveEvent += SaveEventHandler;
    }

    private void SaveEventHandler(object sender, EventArgs e)
    {
        // 在这里处理保存事件
    }
}

public class MyClass
{
    private SaveManager saveManager;

    public MyClass()
    {
        saveManager = new SaveManager();
        saveManager.SaveEvent += SaveEventHandler;
    }

    private void SaveEventHandler(object sender, EventArgs e)
    {
        // 在这里处理保存事件
    }

    public void SaveData()
    {
        saveManager.Save();
    }
}
