实验3：进程管理练习

通过本实验，熟悉和掌握Process类的使用。

1、创建一个WPF应用程序项目

2、将App.xaml中的Application.Resources节内容改为

<Application x:Class="WpfApp1.App"             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"             xmlns:local="clr-namespace:WpfApp1"             StartupUri="MainWindow.xaml">    <Application.Resources>        <Style x:Key="LabelStyle" TargetType="Label">            <Setter Property="FontSize" Value="14"/>            <Setter Property="HorizontalContentAlignment" Value="Center"/>            <Setter Property="HorizontalAlignment" Value="Center" />            <Setter Property="Background" Value="AliceBlue"/>        </Style>        <Style x:Key="BorderStyle" TargetType="Border">            <Setter Property="Height" Value="35"/>            <Setter Property="VerticalAlignment" Value="Center"/>            <Setter Property="Background" Value="AliceBlue"/>        </Style>    </Application.Resources></Application>

3、修改MainWindow.xaml及代码隐藏类

MainWindow.xaml

<Window x:Class="WpfApp1.MainWindow"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"        xmlns:local="clr-namespace:WpfApp1"        mc:Ignorable="d"        Title="MainWindow" Height="450" Width="800">    <Grid Margin="20">        <Grid.ColumnDefinitions>            <ColumnDefinition Width="Auto"/>            <ColumnDefinition Width="*"/>        </Grid.ColumnDefinitions>        <Rectangle Grid.ColumnSpan="2" Fill="White" RadiusX="14" RadiusY="14" Stroke="Blue" StrokeDashArray="3"/>        <Rectangle Grid.Column="0" Margin="7" Fill="#FFF0F9D8" RadiusX="10" RadiusY="10" Stroke="Blue" StrokeDashArray="3"/>        <Rectangle Grid.Column="0" Margin=" 20" Fill="White" Stroke="Blue"/>        <ScrollViewer Grid.Column="0" Margin="20">            <StackPanel>                <StackPanel.Resources>                    <Style TargetType="Button">                        <Setter Property="HorizontalContentAlignment" Value="Center"/>                        <Setter Property="Margin" Value="5 10 5 0"/>                        <Setter Property="Padding" Value=" 15 0 15 0"/>                        <Setter Property="FontSize" Value=" 10"/>                        <EventSetter Event="Click" Handler="button_Click"/>                    </Style>                </StackPanel.Resources>                <Button Content="例1（StartStopProcess）" Tag="/Examples/Page1.xaml"/>                            </StackPanel>        </ScrollViewer>        <Frame Name="frame1" Grid.Column="1" Margin="10" BorderThickness="1" BorderBrush="Blue" NavigationUIVisibility="Hidden"/>    </Grid></Window>

MainWindow.xaml.cs主要内容

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows;using System.Windows.Controls;using System.Windows.Data;using System.Windows.Documents;using System.Windows.Input;using System.Windows.Media;using System.Windows.Media.Imaging;using System.Windows.Navigation;using System.Windows.Shapes;namespace WpfApp1{    /// <summary>    /// MainWindow.xaml 的交互逻辑    /// </summary>    public partial class MainWindow : Window    {        Button oldButton = new Button();        public MainWindow()        {            InitializeComponent();        }        private void button_Click(object sender, RoutedEventArgs e)        {            Button btn = e.Source as Button;            btn.Foreground = Brushes.Black;            oldButton.Foreground = Brushes.Black;            oldButton = btn;            frame1.Source = new Uri(btn.Tag.ToString(), UriKind.Relative);        }    }}

修改Page1.xaml的核心代码

<Page x:Class="WpfApp1.Examples.Page1"      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"       xmlns:d="http://schemas.microsoft.com/expression/blend/2008"       xmlns:local="clr-namespace:WpfApp1.Examples"      mc:Ignorable="d"       d:DesignHeight="450" d:DesignWidth="800"      Title="Page1">    <DockPanel Background="White">        <Label DockPanel.Dock="Top" Content="启动、停止和观察进程"               Style="{StaticResource LabelStyle}"/>        <Border DockPanel.Dock="Bottom" Style="{StaticResource BorderStyle}">            <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">                <Button Name="btnStart" Width="70"                        Content="启动进程" Click="BtnStart_Click"/>                <Button Name="btnStop" Margin="20 0 0 0" Width="70"                        Content="停止进程" Click="BtnStop_Click"/>            </StackPanel>        </Border>        <DataGrid Name="dataGrid1" Background="White" Margin="5"                  IsReadOnly="True" AutoGenerateColumns="False">            <DataGrid.Columns>                <DataGridTextColumn Header="进程ID"                                    Binding="{Binding Path=Id}" Width="50"/>                <DataGridTextColumn Header="进程名称"                                    Binding="{Binding Path=ProcessName}" Width="70"/>                <DataGridTextColumn Header="占用内存"                                    Binding="{Binding Path=TotalMemory}" Width="80"/>                <DataGridTextColumn Header="启动时间"                                    Binding="{Binding Path=StartTime}" Width="130"/>                <DataGridTextColumn Header="文件路径"                                    Binding="{Binding Path=FileName}"/>                            </DataGrid.Columns>         </DataGrid>    </DockPanel></Page>

Page1.xaml.cs的核心代码

using System;using System.Collections.Generic;using System.Diagnostics;using System.IO;using System.Linq;using System.Text;using System.Threading;using System.Threading.Tasks;using System.Windows;using System.Windows.Controls;using System.Windows.Data;using System.Windows.Documents;using System.Windows.Input;using System.Windows.Media;using System.Windows.Media.Imaging;using System.Windows.Navigation;using System.Windows.Shapes;namespace WpfApp1.Examples{    /// <summary>    /// Page1.xaml 的交互逻辑    /// </summary>    public partial class Page1 : Page    {        int fileIndex = 1;        string fileName = "Notepad";        List<Data> list = new List<Data>();        public Page1()        {            InitializeComponent();        }        private void BtnStart_Click(object sender, RoutedEventArgs e)        {            string argument = Environment.CurrentDirectory + "\\myfile" + (fileIndex++) + ".txt";            if (File.Exists(argument)==false)            {                File.CreateText(argument);            }            Process p = new Process();            p.StartInfo.FileName = fileName;            p.StartInfo.Arguments = argument;            p.StartInfo.UseShellExecute = false;            p.StartInfo.WindowStyle = ProcessWindowStyle.Normal;            p.Start();            p.WaitForInputIdle();            RefreshProcessInfo();        }        private void BtnStop_Click(object sender, RoutedEventArgs e)        {            this.Cursor = Cursors.Wait;            Process[] myprocesses;            myprocesses = Process.GetProcessesByName(fileName);            foreach (Process p in myprocesses)            {                using (p)                {                    p.CloseMainWindow();                    Thread.Sleep(1000);                    p.WaitForExit();                }            }            fileIndex = 0;            RefreshProcessInfo();            this.Cursor = Cursors.Arrow;        }        private void RefreshProcessInfo()        {            dataGrid1.ItemsSource = null;            list.Clear();            Process[] processes = Process.GetProcessesByName(fileName);            foreach (Process p in processes)            {                list.Add(new Data() {                   Id = p.Id,                   ProcessName = p.ProcessName,                   TotalMemory = string.Format("{0,10:0} KB" ,p.WorkingSet64 / 1024d),                   StartTime=p.StartTime.ToString("yyyy-M-d HH:mm:ss"),                   FileName=p.MainModule.FileName                });            }            dataGrid1.ItemsSource = list;        }    }    public class Data    {        public int Id { get; set; }        public string ProcessName { get; set; }        public string TotalMemory { get; set; }        public string StartTime { get; set; }        public string FileName { get; set; }    }}

实验结果

实验结果能启动多个进程，并停止所有进程

通过本实验，对Process类的使用，启动进程，停止进程，获取所有进程信息，获取指定进程信息，更加熟练和掌握了进程管理知识。
