设计一个护眼小工具,其主要功能包括设置工作时间和休息时间,以及在休息时间自动锁屏并显示倒计时,可以用C#编程语言来实现。以下是一个基本的设计方案,分为几个关键部分:
以下是一个简化的示例代码框架,演示了如何在C#中实现这些功能:
using System;
using System.Timers;
using System.Windows.Forms;
public partial class EyeCareForm : Form
{
private Timer workTimer;
private Timer breakTimer;
private int workTime; // in minutes
private int breakTime; // in minutes
public EyeCareForm()
{
InitializeComponent();
workTimer = new Timer();
workTimer.Elapsed += OnWorkTimeElapsed;
breakTimer = new Timer();
breakTimer.Elapsed += OnBreakTimeElapsed;
}
private void startButton_Click(object sender, EventArgs e)
{
workTime = (int)workTimeNumericUpDown.Value;
breakTime = (int)breakTimeNumericUpDown.Value;
workTimer.Interval = workTime * 60000;
workTimer.Start();
}
private void OnWorkTimeElapsed(object sender, ElapsedEventArgs e)
{
workTimer.Stop();
// Lock screen and start break timer
LockScreen();
breakTimer.Interval = breakTime * 60000;
breakTimer.Start();
}
private void OnBreakTimeElapsed(object sender, ElapsedEventArgs e)
{
breakTimer.Stop();
// Unlock screen and restart work timer
UnlockScreen();
workTimer.Start();
}
private void LockScreen()
{
// Code to lock screen and display countdown
}
private void UnlockScreen()
{
// Code to unlock screen
}
}
workTimeNumericUpDown
和 breakTimeNumericUpDown
是用户用来设置工作和休息时间的控件。startButton_Click
方法启动工作计时器。OnWorkTimeElapsed
在工作时间结束时触发,启动休息计时器并锁屏。OnBreakTimeElapsed
在休息时间结束时触发,解锁屏幕并重新启动工作计时器。LockScreen
和 UnlockScreen
需要根据实际情况实现锁屏和解锁的具体逻辑。这只是一个基础的框架,具体的实现需要根据实际需求和环境进行调整和完善。例如,锁屏功能可能需要调用操作系统特定的API,而界面的美观和用户体验也需要进一步设计。
使用WPF (Windows Presentation Foundation) 来实现一个护眼小工具,你需要创建一个主界面,设置计时器,并实现锁屏与倒计时的功能。以下是一个基本的实现方法:
首先,你需要在Visual Studio中创建一个新的WPF应用程序项目。
在主界面(如MainWindow.xaml
)中,你可以添加两个滑动条(Slider)或数字输入框(TextBox)用于设置工作时间和休息时间,以及两个按钮来控制计时器的启动和停止。
<Window x:Class="EyeCareTool.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="护眼小工具" Height="350" Width="525">
<Grid>
<StackPanel VerticalAlignment="Center" HorizontalAlignment="Center">
<Label Content="工作时间(分钟):"/>
<Slider x:Name="workTimeSlider" Minimum="1" Maximum="120" TickFrequency="1" IsSnapToTickEnabled="True"/>
<Label Content="休息时间(分钟):"/>
<Slider x:Name="breakTimeSlider" Minimum="1" Maximum="30" TickFrequency="1" IsSnapToTickEnabled="True"/>
<Button x:Name="startButton" Content="开始" Click="StartButton_Click"/>
<Button x:Name="stopButton" Content="停止" Click="StopButton_Click"/>
StackPanel>
Grid>
Window>
在代码后台(如MainWindow.xaml.cs
),你需要创建计时器并处理开始和停止按钮的点击事件。
using System.Windows;
using System.Windows.Threading;
namespace EyeCareTool
{
public partial class MainWindow : Window
{
private DispatcherTimer workTimer;
private DispatcherTimer breakTimer;
public MainWindow()
{
InitializeComponent();
workTimer = new DispatcherTimer();
workTimer.Tick += WorkTimer_Tick;
breakTimer = new DispatcherTimer();
breakTimer.Tick += BreakTimer_Tick;
}
private void StartButton_Click(object sender, RoutedEventArgs e)
{
workTimer.Interval = TimeSpan.FromMinutes(workTimeSlider.Value);
workTimer.Start();
}
private void StopButton_Click(object sender, RoutedEventArgs e)
{
workTimer.Stop();
breakTimer.Stop();
// 也可以在这里解锁屏幕
}
private void WorkTimer_Tick(object sender, EventArgs e)
{
workTimer.Stop();
// 执行锁屏操作
LockScreen();
breakTimer.Interval = TimeSpan.FromMinutes(breakTimeSlider.Value);
breakTimer.Start();
}
private void BreakTimer_Tick(object sender, EventArgs e)
{
breakTimer.Stop();
// 解锁屏幕
UnlockScreen();
// 可以选择是否重新启动工作计时器
}
private void LockScreen()
{
// 实现锁屏逻辑
}
private void UnlockScreen()
{
// 实现解锁屏幕逻辑
}
}
}
锁屏和倒计时的实现取决于你的具体需求。你可以创建一个新的全屏窗口作为锁屏界面,并在该界面上显示倒计时。倒计时结束后,关闭这个窗口以解锁屏幕。
这个示例提供了一个基本的框架,你可以根据具体需求进行扩展和优化。
