在 WPF 中使用超链接的示例 [英] Example using Hyperlink in WPF

问题描述

我看到了一些建议，您可以通过Hyperlink控件向WPF应用程序添加超链接.

I've seen several suggestions, that you can add hyperlink to WPF application through Hyperlink control.

这是我在代码中尝试使用它的方式:

Here's how I'm trying to use it in my code:

<Window
        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" 
        mc:Ignorable="d" 
        x:Class="BookmarkWizV2.InfoPanels.Windows.UrlProperties"
        Title="UrlProperties" Height="754" Width="576">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition></RowDefinition>
            <RowDefinition Height="40"/>
        </Grid.RowDefinitions>
        <Grid>
            <ScrollViewer ScrollViewer.VerticalScrollBarVisibility="Auto" Grid.RowSpan="2">
                <StackPanel >
                    <DockPanel LastChildFill="True" Margin="0,5">
                        <TextBlock Text="Url:" Margin="5" 
                            DockPanel.Dock="Left" VerticalAlignment="Center"/>
                        <TextBox Width="Auto">
                            <Hyperlink NavigateUri="http://www.google.co.in">
                                    Click here
                            </Hyperlink>   
                        </TextBox>                      
                    </DockPanel >
                </StackPanel>
            </ScrollViewer>        
        </Grid>
        <StackPanel HorizontalAlignment="Right" Orientation="Horizontal" Margin="0,7,2,7" Grid.Row="1" >
            <Button Margin="0,0,10,0">
                <TextBlock Text="Accept" Margin="15,3" />
            </Button>
            <Button Margin="0,0,10,0">
                <TextBlock Text="Cancel" Margin="15,3" />
            </Button>
        </StackPanel>
    </Grid>
</Window>

我收到以下错误:

属性文本"不支持超链接"类型的值.

Property 'Text' does not support values of type 'Hyperlink'.

我做错了什么?

推荐答案

如果您希望您的应用程序打开 网络浏览器 你需要添加一个HyperLink 将 RequestNavigate 事件设置为一个函数以编程方式打开一个以地址为参数的网络浏览器.

If you want your application to open the link in a web browser you need to add a HyperLink with the RequestNavigate event set to a function that programmatically opens a web-browser with the address as a parameter.

<TextBlock>           
    <Hyperlink NavigateUri="http://www.google.com" RequestNavigate="Hyperlink_RequestNavigate">
        Click here
    </Hyperlink>
</TextBlock>

在代码隐藏中，您需要添加类似的内容来处理 RequestNavigate 事件:

In the code-behind you would need to add something similar to this to handle the RequestNavigate event:

private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e)
{
    // for .NET Core you need to add UseShellExecute = true
    // see https://docs.microsoft.com/dotnet/api/system.diagnostics.processstartinfo.useshellexecute#property-value
    Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri));
    e.Handled = true;
}

此外，您还需要以下导入:

In addition you will also need the following imports:

using System.Diagnostics;
using System.Windows.Navigation;

它在您的应用程序中将如下所示:

It will look like this in your application:
