C#桌面应用开发实现番茄定时器
作者：Leapahead1949
本文主要介绍了C#桌面应用开发实现番茄定时器,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧
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;
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;
}
}
