MainPage.xaml中

<StackPanel Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">        <TextBlock  Height="200" TextWrapping="Wrap"  Loaded="TextBlock_Loaded" Tapped="TextBlock_Tapped">            dsdsdsdsadsadddsdsdsdhttp://www.baidu.com dsadsadsadsahttps://www.baidu.com1 daewqewqeqwewqdaewq            dsdsdsdsadsadddsdsdsdhttp://www.baidu.com6 dsadsadsadsahttps://www.baidu.com2 daewqewqeqwewqdaewq            dsdsdsdsadsadddsdsdsdhttp://www.baidu.com7 dsadsadsadsahttps://www.baidu.com3 daewqewqeqwewqdaewq            dsdsdsdsadsadddsdsdsdhttp://www.baidu.com8 dsadsadsadsahttps://www.baidu.com4 daewqewqeqwewqdaewq            dsdsdsdsadsadddsdsdsdhttp://www.baidu.com9 dsadsadsadsahttps://www.baidu.com5 daewqewqeqwewqdaewq            <FlyoutBase.AttachedFlyout>                <Flyout x:Name="HyperText" Placement="Full">                    <StackPanel>                        <ListView Name="ttt" SelectionChanged="ttt_SelectionChanged"/>                    </StackPanel>                </Flyout>            </FlyoutBase.AttachedFlyout>        </TextBlock>        <StackPanel Orientation="Horizontal">            <Button Content="粘贴超链接" Click="Button_Click" />            <TextBox  Name="hhh"/>        </StackPanel>            </StackPanel>

MainPage.cs中

using System.Text.RegularExpressions;using Windows.ApplicationModel.DataTransfer;           private void TextBlock_Loaded(object sender, RoutedEventArgs e)        {            string str = ((TextBlock)sender).Text.ToString().ToLower();            string pattern = @"https?://[^\s]+\s";            MatchCollection mc = Regex.Matches(str, pattern);            if(mc.Count > 0)            {                ttt.Items.Clear();                foreach (Match t in mc)                {                    ttt.Items.Add(t.Value.ToString().Trim());                }            }        }        private void ttt_SelectionChanged(object sender, SelectionChangedEventArgs e)        {            var ddd = (ListView)sender;            DataPackage dp = new DataPackage();            dp.SetText(ddd.SelectedItem.ToString());            Clipboard.SetContent(dp);            HyperText.Hide();        }        private void TextBlock_Tapped(object sender, TappedRoutedEventArgs e)        {            var fff = (TextBlock)sender;            FlyoutBase.ShowAttachedFlyout(fff);        }        private async void Button_Click(object sender, RoutedEventArgs e)        {            DataPackageView con = Clipboard.GetContent();                        if (con.Contains(StandardDataFormats.Text))            {                hhh.Text = await con.GetTextAsync();            }        }

实现的效果如下：
