用WPF设计一个简易的休息提醒闹钟

最近利用工作之余，写了一个WPF程序玩玩，用来提醒自己在长时间学习后要休息一会儿哈哈，功能很简单，没啥难点

一.视频演示地址

可以设定间隔提醒时长和休息时长，点击开始之后会开始计时，当计时达到设定的间隔时常后，会进入休息页面会播放音乐，同时也会开始计时，当计时达到休息时长后，会关闭音乐并返回主页。

二.代码展示

思路很简单，直接展示一些核心代码吧：

1. 项目截图：

2. App.xaml.cs代码，用于配置Prism框架一些服务以及初始化工作：

using AlarmWPF.ViewModels;
using AlarmWPF.Views;
using Prism.Ioc;
using System.Windows;namespace AlarmWPF
{/// <summary>/// Interaction logic for App.xaml/// </summary>public partial class App{protected override Window CreateShell(){return Container.Resolve<MainWindow>();}protected override void RegisterTypes(IContainerRegistry containerRegistry){containerRegistry.RegisterDialog<RestView,RestViewModel>();}}
}

3. MainWindow.xaml代码

<Window x:Class="AlarmWPF.Views.MainWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:prism="http://prismlibrary.com/"xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"prism:ViewModelLocator.AutoWireViewModel="True"xmlns:hc="https://handyorg.github.io/handycontrol" ResizeMode="NoResize"Title="{Binding Title}" Height="350" Width="525" WindowStartupLocation="CenterScreen" Icon="/Images/alarmIcon.png" Unloaded="Window_Unloaded"><Grid><Grid.RowDefinitions><RowDefinition/><RowDefinition/><RowDefinition/><RowDefinition/></Grid.RowDefinitions><StackPanel Grid.Row="0" Orientation="Horizontal"><TextBlock Style="{StaticResource MaterialDesignHeadline6TextBlock}"  VerticalAlignment="Center" Margin="16 0 0 0" Text="间隔多少分钟提醒：" FontSize="20" FontWeight="Bold"/><hc:NumericUpDown Value="{Binding InternalMinutes}" HorizontalAlignment="Center"  VerticalAlignment="Center" Style="{StaticResource NumericUpDownBaseStyle}" Width="150" FontSize="20" FontWeight="Bold"/></StackPanel><StackPanel Grid.Row="1" Orientation="Horizontal"><TextBlock Style="{StaticResource MaterialDesignHeadline6TextBlock}"  VerticalAlignment="Center" Margin="16 0 0 0" Text="休息多少分钟：" FontSize="20" FontWeight="Bold"/><hc:NumericUpDown Value="{Binding RestMinutes}" HorizontalAlignment="Center"  VerticalAlignment="Center" Style="{StaticResource NumericUpDownBaseStyle}" Width="150" FontSize="20" FontWeight="Bold"/></StackPanel><Grid Grid.Row="3"><Grid.ColumnDefinitions><ColumnDefinition/><ColumnDefinition/></Grid.ColumnDefinitions><Button Command="{Binding BtnStart}" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"  IsEnabled="{Binding BtnStartEnable}" Grid.Column="0" Style="{StaticResource MaterialDesignFlatDarkBgButton}" Content="开始" HorizontalAlignment="Center" VerticalAlignment="Center"/><Button Command="{Binding BtnStop}" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}" IsEnabled="{Binding BtnStopEnable}"  Grid.Column="1" Style="{StaticResource MaterialDesignFlatDarkBgButton}" Content="停止" HorizontalAlignment="Center" VerticalAlignment="Center"/></Grid></Grid>
</Window>

4. MainWindowViewModel.cs代码：

using AlarmWPF.Views;
using HandyControl.Tools.Extension;
using Microsoft.Win32;
using Prism.Commands;
using Prism.Mvvm;
using Prism.Services.Dialogs;
using System;
using System.Diagnostics;
using System.IO;
using System.Threading;
using System.Threading.Tasks;
using System.Timers;
using System.Windows;
using System.Windows.Controls;
using Timer = System.Timers.Timer;namespace AlarmWPF.ViewModels
{public class MainWindowViewModel : BindableBase{#region 属性private string _title = "自律闹钟";public string Title{get { return _title; }set { SetProperty(ref _title, value); }}private int internalMinutes;public int InternalMinutes{get { return internalMinutes; }set { SetProperty(ref internalMinutes, value); }}private int restMinutes;public int RestMinutes{get { return restMinutes; }set { SetProperty(ref restMinutes, value); }}private bool btnStartEnable=true;public bool BtnStartEnable{get { return btnStartEnable; }set { SetProperty(ref btnStartEnable, value); }}private bool btnStopEnable=true;public bool BtnStopEnable{get { return btnStopEnable; }set { SetProperty(ref btnStopEnable, value); }}public DelegateCommand<object> BtnStart { get; set; }public DelegateCommand<object> BtnStop { get; set; }private int endSeconds = 0;Timer timer;private IDialogService dialog;private Window window1;#endregionpublic MainWindowViewModel(IDialogService dialog){window1 = new Window();this.dialog = dialog;BtnStart = new DelegateCommand<object>(Start);BtnStop = new DelegateCommand<object>(Stop);timer = new Timer(1000);timer.Enabled = false;timer.Elapsed += Timer_Elapsed;}private void Stop(object obj){BtnStartEnable = true;BtnStopEnable = false;timer.Stop();timer.Enabled = false;}private void Start(object obj){endSeconds = InternalMinutes * 60;BtnStartEnable = false;BtnStopEnable = true;timer.Enabled = true;timer.Start();window1 = obj as Window;window1.WindowStartupLocation = WindowStartupLocation.CenterScreen;}private void Timer_Elapsed(object sender, ElapsedEventArgs e){endSeconds--;if (endSeconds==0){timer.Stop();timer.Enabled=false;///parameters，添加向对话框传递的参数IDialogParameters parameters = new DialogParameters();parameters.Add("InternalMinutes", $"{InternalMinutes}");parameters.Add("RestMinutes", $"{RestMinutes}");Application.Current.Dispatcher.InvokeAsync(new Action(() =>{window1.Hide();dialog.ShowDialog("RestView",parameters,callback);}));}}/// <summary>/// 对话框关闭的时候调用此回调方法/// </summary>/// <param name="obj"></param>private void callback(IDialogResult obj){window1.WindowStartupLocation = WindowStartupLocation.CenterScreen;window1.Show();BtnStartEnable = true;BtnStopEnable = false;}}
}

5. RestView.xaml
