c# - 如何将所选文本转换为 RichEditBox 中的超链接

Question

我试过下面的代码，但它抛出异常System.ArgumentException，异常信息是:

Value does not fall within the expected range.

public void InsertLink(RichEditBox control) 
{  
    control.Document.Selection.Link ="http://www.bing.com";
}

Answer 1

The text it contains must be enclosed in quotes, optionally preceded by the sentinel character 0xFDDF. For example: "http://www.msn.com" or 0xFDDF"http://www.msn.com".

您可以从 MSDN source 获得更多详细信息.

因此您需要像下面这样更改您的代码:

<StackPanel Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <RichEditBox x:Name="richeditbox" Height="200">
    </RichEditBox>
    <Button Content="Convert to hypelink" Click="Button_Click"></Button>
</StackPanel>

private void Button_Click(object sender, RoutedEventArgs e)
{
    richeditbox.Document.Selection.Link = "\"http://www.bing.com\"";  
}
