C# 无法将tye HyperLink的值添加到TextBlock的InlineCollection

我在这段代码中得到了这个错误：

<TextBlock>
   <Run>let me</Run>
   <Hyperlink NavigateUri="http://www.google.com">google</Hyperlink>
   <Run>that for you</Run>
</TextBlock>

您可以使用dependency属性将“带有超链接的文本”绑定到RichTextBlock

RichEditBox

。它会将每个超链接转换为

超链接按钮

。我建议您自定义

RichEditBox

，使其看起来更像

TextBlock

。还可以自定义

HyperlinkButton

以内联显示

从中复制和调整代码

尝试添加Target=“\u blank”

中的。呃……我以为它是

超链接按钮

。你不能使用它，你必须使用

RichTextBlock

。检查一下windows phone中没有

RichTextBlock

。

RichTextBlock

在windows phone中不存在：|而且该代码是2005年的：））啊，请稍候，我正在转换WP的代码，我希望它能起作用。
