XAML代码例如以下：

<Window x:Class="Demo006.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="MainWindow" Height="240" Width="360" WindowStyle="ToolWindow">

    <Grid>

        <Grid.RowDefinitions>

            <RowDefinition Height="24" />

            <RowDefinition Height="4" />

            <RowDefinition Height="24" />

            <RowDefinition Height="4" />

            <RowDefinition Height="24" />

            <RowDefinition Height="4" />

            <RowDefinition Height="*" />

        </Grid.RowDefinitions>

        <TextBlock  Grid.Row="0" Text="Name:" VerticalAlignment="Center" HorizontalAlignment="Left" />

        <TextBox Grid.Row="0" Name="NameTextBox" Margin="60,0,0,0" />

        <Button Grid.Row="2" Content="New Teacher" Command="New" CommandParameter="Teacher" />

        <Button Grid.Row="4" Content="New Student" Command="New" CommandParameter="Student" />

        <ListBox Grid.Row="6" Name="NewItemListBox" Height="117" VerticalAlignment="Bottom" />

    </Grid>

    <Window.CommandBindings>

        <CommandBinding Command="New"

                        CanExecute="CommandBinding_CanExecute"

                        Executed="CommandBinding_Executed" />

    </Window.CommandBindings>

</Window>

相关的事件处理器代码例如以下所看到的：

private void CommandBinding_CanExecute(object sender, CanExecuteRoutedEventArgs e)

{

    if (string.IsNullOrEmpty(this.NameTextBox.Text) == true) e.CanExecute = false;

    else e.CanExecute = true;

}

private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e)

{

    string name = this.NameTextBox.Text;

    if (e.Parameter.ToString() == "Teacher")

    {

        this.NewItemListBox.Items.Add(string.Format("New Teacher: {0}， 学而不厌，诲人不倦。", name));

    }

    else if (e.Parameter.ToString() == "Student")

    {

        this.NewItemListBox.Items.Add(string.Format("New Student: {0}，好好学习，天天向上。", name));

    }

}
