弹出控件上的超链接找不到超链接文件

问题描述

出于某种原因，hyperlink 控件上的以下 popup 无法打开 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，所使用的链接 (https://www.google.com/) 可以正常工作。我在这里可能缺少什么，我们可以让它发挥作用吗？

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());
}

解决方法

事实证明，问题实际上与应用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 帖子中：如果您的应用无法找到浏览器的路径该怎么办
2. Ahmad Hindash 在他关于如何查找浏览器位置的 this 帖子中
3. Dxiv on details on 为什么有时您可能会收到上述错误。

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());
}
