架构师训练营 Week03

• 请在草稿纸上手写一个单例模式的实现代码，拍照提交作业



• 请用组合设计模式编写程序，打印输出图 1 的窗口，窗口组件的树结构如图 2 所示，打印输出示例参考图 3



• 基类的定义

public class BaseFrame

{

protected string Content;

protected IList<BaseFrame> FramesList;

public BaseFrame(string content)

{

Content = content;

this.FramesList = new List<BaseFrame>();

}

public virtual void Add(BaseFrame _baseFrame)

{

if(_baseFrame == null)

{

return;

}

if(_baseFrame.FramesList.Count() > 0)

{

foreach(var item in _baseFrame.FramesList)

{

this.FramesList.Add(item);

}

}

else

{

this.FramesList.Add(_baseFrame);

}

}

public virtual void Delete(BaseFrame _baseFrame)

{

if (_baseFrame == null)

{

return;

}

if (this.FramesList.Count() > 0)

{

foreach (var item in _baseFrame.FramesList)

{

this.FramesList.Remove(item);

}

}

else

{

this.FramesList.Remove(_baseFrame);

}

}

public virtual void Print()

{

if(this.FramesList.Count > 0)

{

foreach(var item in this.FramesList)

{

Console.WriteLine(item.Content);

}

}

else

{

Console.WriteLine(this.Content);

}

}

}



• 子类的定义

public class WinFormWnd : BaseFrame

{

public WinFormWnd(string content) : base(content) { }

}

public class Picture : BaseFrame

{

public Picture(string content) : base(content) { }

}

public class Button : BaseFrame

{

public Button(string content) : base(content) { }

}

public class Frame : BaseFrame

{

public Frame(string content) : base(content) { }

}

public class Label : BaseFrame

{

public Label(string content) : base(content) { }

}

public class TextBox : BaseFrame

{

public TextBox(string content) : base(content) { }

}

public class PasswordBox : BaseFrame

{

public PasswordBox(string content) : base(content) { }

}

public class CheckBox : BaseFrame

{

public CheckBox(string content) : base(content) { }

}

public class LinkLabel : BaseFrame

{

public LinkLabel(string content) : base(content) { }

}



• 主函数入口:

static void Main(string[] args)

{

BaseFrame wnd = new WinFormWnd("Window窗口");

wnd.Add(new Picture("LOGO图片"));

wnd.Add(new Button("登录"));

wnd.Add(new Button("注册"));

var frame1 = new Frame("Frame1");

frame1.Add(new Label("用户名"));

frame1.Add(new Label("密码"));

frame1.Add(new PasswordBox("密码框"));

frame1.Add(new Label("记住"));

frame1.Add(new CheckBox("复选框"));

frame1.Add(new TextBox("文本框"));

frame1.Add(new LinkLabel("忘记密码"));

wnd.Add(frame1);

Console.WriteLine("****Print Wnd********");

wnd.Print();

Console.WriteLine("****Print Frame1********");

frame1.Print();

Console.ReadKey();

}
