做项目的时候遇见了这个问题,在网上查找了一些资料之后解决了这个问题,我把我的代码贴出来分享一下。

先说我的要求:主窗口上有五个TextBlock控件和两个Button按钮(Get和Set),单击Get按钮之后弹出一个对话框,显示出所有TextBlock控件的Name值;单击Set按钮之后,将所有的TextBlock的背景色设为红色。

这是主窗体的代码(控件是手动拖的,所有属性值有点乱):

<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    x:Class="ExplodeProgram.MainWindow"
    x:Name="Window"
    Title="MainWindow"
    Width="600" Height="400" xmlns:my="clr-namespace:ExplodeProgram">

    <Grid x:Name="LayoutRoot">
        <TextBlock Name="hello" Margin="78,77,98,196" TextWrapping="Wrap" Foreground="#FFFB240F" FontSize="64">
            <Run Language="zh-cn" Text="Hello World!"/></TextBlock>
        <TextBlock Height="23" HorizontalAlignment="Left" Margin="30,179,0,0" Name="textBlock1" 
                   Text="TextBlock1" VerticalAlignment="Top" Width="100" />
        <TextBlock Height="23" HorizontalAlignment="Left" Margin="136,179,0,0" Name="textBlock2" 
                   Text="TextBlock2" VerticalAlignment="Top" Width="100" />
        <TextBlock Height="23" HorizontalAlignment="Left" Margin="291,179,0,0" Name="textBlock3" 
                   Text="TextBlock3" VerticalAlignment="Top" Width="100" />
        <TextBlock Height="23" HorizontalAlignment="Left" Margin="420,179,0,0" Name="textBlock4" 
                   Text="TextBlock4" VerticalAlignment="Top" Width="100" />

        <Button x:Name="get" Content="Get" Margin="102,0,411,45" VerticalAlignment="Bottom" Height="25" Width="65" Click="get_Click" />
        <Button x:Name="set" Content="Set" Width="65" Height="25" Click="set_Click" Margin="185,291,328,45" />
    </Grid>
</Window>

这是后台单击事件的代码:

 private void set_Click(object sender, RoutedEventArgs e)
        {
            foreach (UIElement element in LayoutRoot.Children)
            {
                if (element is TextBlock)
                {
                    TextBlock current = ((TextBlock)element);
                    //设置背景
                    current.Background = Brushes.Red;
                }
            }

        }

        private void get_Click(object sender, RoutedEventArgs e)
        {
            string str = "";
            foreach (UIElement element in LayoutRoot.Children)
            {
                if (element is TextBlock)
                {
                    TextBlock current = ((TextBlock)element);
                    str += current.Name + "\r\n";
                }
            }
            //显示Name值
            MessageBox.Show(str);
        }

搞定。
