experiment 3： Process management exercise

Through this experiment , Be familiar with and master Process The use of the class .

1、 Create a WPF Application project

2、 take App.xaml Medium Application.Resources The content of this section is changed to

<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、 modify MainWindow.xaml And code hiding classes

experimental result

The experimental results can start multiple processes , And stop all processes

Through this experiment , Yes Process The use of the class , Start the process , Stop the process , Get all process information , Get the specified process information , More proficient and master the process management knowledge .
