弹出控件上的超链接找不到超链接文件

Question

由于某种原因，popup 控件上的以下 hyperlink 未打开 google 网站。弹出窗口正确显示了链接，但是当我单击链接时，出现以下错误。如果我直接在浏览器上使用，使用的链接 (https://www.google.com/) 可以正常工作。我可能在这里遗漏了什么，我们可以让它工作吗？

错误：

MainWindow.xaml：

.....
 <Grid>
        <TextBlock TextWrapping="Wrap">text <Run TextDecorations="Underline" MouseEnter="run_MouseEnter">link</Run>
        </TextBlock>
        <Popup Name="popLink" StaysOpen="False" Placement="Mouse" MaxWidth="200" PopupAnimation="Slide" AllowsTransparency = "True">
            <Border BorderBrush="Beige" BorderThickness="2" Background="White">
                <TextBlock Margin="10" TextWrapping="Wrap"> <Hyperlink Click="Hyperlink_Click" NavigateUri="https://www.google.com/">More info</Hyperlink>
                </TextBlock>
        </Border>
    </Popup>
</Grid>

MainWindow.xaml.cs：

private void run_MouseEnter(object sender, MouseEventArgs e)
{
    popLink.IsOpen = true;
}

private void Hyperlink_Click(object sender, RoutedEventArgs e)
{
    System.Diagnostics.Process.Start(((Hyperlink)sender).NavigateUri.ToString());
}

Answer 1

事实证明，该问题实际上与应用程序无法找到默认浏览器的位置有关（在我的情况下为 Chrome）。我通过阅读以下帖子发现了问题的原因：

俗话说：Give credit where credit is due。因此，功劳归于以下用户：

1. Felipe Oriani 在他的 this 上发帖：如果您的应用无法找到浏览器的路径怎么办
2. Ahmad Hindash 在他的 this 帖子中关于如何找到浏览器的位置
3. Dxiv on details on 为什么有时会出现上述错误。

根据我对上述帖子的阅读，我能够解决以下问题：

private void Hyperlink_Click(object sender, RoutedEventArgs e)
{
   //PLEASE NOTE: You would want to programmatically find the location of you browser as user `Felipe Oriani` did in his above mentioned post. For brevity, I am leaving that part.
   System.Diagnostics.Process.Start(@"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe", ((Hyperlink)sender).NavigateUri.ToString());
}
