C#桌面应用开发：番茄定时器

1、环境搭建和工程创建：

步骤一：安装visual studio2022

步骤二：新建工程
在这里插入图片描述

2、制作窗体部件

*踩过的坑：

（1）找不到工具箱控件，现象如下：

在这里插入图片描述

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
在这里插入图片描述

若上述在这里插入图片描述
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：

在这里插入图片描述

4、具体功能函数

using System.Windows.Forms;
using static System.Windows.Forms.VisualStyles.VisualStyleElement;namespace MyProject01
{public partial class Form1 : Form{UInt16 Timer_Value = 0; //定时值UInt16 Timer_Count = 0; //定时器计数值byte Timer_Status = 0;  //定时器状态 0--停止  1 -- 定时状态  2 --暂停状态public Form1(){InitializeComponent();}private void textBox1_TextChanged(object sender, EventArgs e){}private void button1_Click(object sender, EventArgs e){}private void label1_Click(object sender, EventArgs e){}private void button2_Click(object sender, EventArgs e){}private void flowLayoutPanel1_Paint(object sender, PaintEventArgs e){}private void label1_Click_1(object sender, EventArgs e){}private void label2_Click(object sender, EventArgs e){}private void label4_Click(object sender, EventArgs e){}private void Form1_Load(object sender, EventArgs e){byte i;for (i = 0; i < 60; i++){//分钟和秒钟的组合框初始化comboBox1.Items.Add(i.ToString());comboBox2.Items.Add(i.ToString());comboBox1.Text = "45";  //初始化为45分钟comboBox2.Text = "0";}}private void comboBox1_SelectedIndexChanged(object sender, EventArgs e){}private void textBox1_TextChanged_1(object sender, EventArgs e){textBox1.ReadOnly = true;}private void button1_Click_1(object sender, EventArgs e){//定时器状态机函数switch (Timer_Status){case 0:{//获取定时时间，分钟*60+秒钟Timer_Value = Convert.ToUInt16(comboBox1.Text, 10);Timer_Value *= 60;Timer_Value += Convert.ToUInt16(comboBox2.Text, 10);if (Timer_Value > 0){//开始定时任务textBox1.Text = Timer_Value.ToString() + " 秒";button1.Text = "暂停计时";button2.Enabled = true;comboBox1.Enabled = false;  //关闭时间选择comboBox2 .Enabled = false;timer1.Start();Timer_Status = 1;}else{MessageBox.Show("定时时间不能为0，请重新输入", "警告");//}//进度条初始化progressBar1.Value = 0;progressBar1.Maximum = Timer_Value;break;}case 1:{timer1.Stop();Timer_Status = 2;button1.Text = "继续计时";break;}case 2:{timer1.Start();Timer_Status = 1;button1.Text = "暂停计时";break;}default:{break;}}}//定时按钮单击事件private void timer1_Tick(object sender, EventArgs e){Timer_Count++;textBox1.Text = Timer_Value-Timer_Count + " 秒";//更新进度条progressBar1.Value = Timer_Count;if (Timer_Count == Timer_Value){timer1.Stop();Timer_Count = 0;System.Media.SystemSounds.Asterisk.Play();button1.Text = "计时结束";MessageBox.Show ("定时时间到","提示");button1.Text = "开始定时";comboBox1.Enabled = true;  //关闭时间选择comboBox2.Enabled = true;comboBox1.Text = "45";  //初始化为45分钟comboBox2.Text = "0";button2.Enabled = false;Timer_Status = 0;progressBar1.Value = 0;}}private void comboBox2_SelectedIndexChanged(object sender, EventArgs e){}private void button2_Click_1(object sender, EventArgs e){if(Timer_Status > 0){Timer_Value = 0; //定时值Timer_Count = 0;Timer_Status = 0;progressBar1.Value = 0;textBox1.Text= "0";}timer1.Stop();Timer_Count = 0;button1.Text = "开始定时";comboBox1.Enabled = true;  //关闭时间选择comboBox2.Enabled = true;comboBox1.Text = "45";  //初始化为45分钟comboBox2.Text = "0";button2.Enabled = false;Timer_Status = 0;Timer_Value = 0;}}
