C#桌面应用开发实现番茄定时器

目录

• 1、环境搭建和工程创建：
• 2、制作窗体部件
• 3、界面布局设计
• 4、具体功能函数

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hSzImGe
