1、环境搭建和工程创建：
步骤一：安装visual studio2022
步骤二：新建工程
2、制作窗体部件
*踩过的坑：
（1）找不到工具箱控件，现象如下：
解决办法：
依次点击：工具栏->获取工具和功能->单个组件：安装3.5版本开发工具
若上述
办法不生效，继续检查.NET桌面开发和ASP.NET开发是否勾选
最后点击顶部栏的：视图->工具箱就能显示出工具栏
3、界面布局设计
（1）界面设计如下：
4、具体功能函数

using System.Windows.Forms;
using static System.Windows.Forms.VisualStyles.VisualStyleElement;
