1、窗体和控件设计
- GUI界面程序的创建和CUI界面类似，直接VS创建 C# windows 窗体应用即可。
- 创建后默认会有一个Program.cs和一个Form1窗体。
Program里决定了启动运行的窗体，Form1是系统自带的。 - 在菜单栏的项目里可以添加窗体
- 可以通过左边的工具箱为窗体添加控件，常用的有按钮，文本框，文字显示等。
右键属性可以更改控件的长宽高等设置。
双击控件会进入控件默认触发事件的程序编辑模式（当然也可以自己写别的）。
- 可以通过这两行代码实现在一个窗体中打开另一个窗体。
Form2 f2 = new Form2();
f2.ShowDialog();
