推荐答案

使用 超链接.

<TextBlock>
    <Run>Pure Text</Run>
    <Hyperlink Command="{Binding HyperLinkTapped}">http://google.com</Hyperlink>
    <Run>Pure Text Again</Run>
</TextBlock>

Windows Phone 7.1 (Mango) 支持此功能.

This is supported from Windows Phone 7.1 (Mango).

如有必要，您可以在运行时根据您的数据创建自己的 FlowDocument.

You can create your own FlowDocument from the your data, at runtime, if necessary.

关于如何从字符串生成 FlowDocument 的示例:

Example on how to generate a FlowDocument from a string:

private void OnMessageReceived(string message)
{
    var textBlock = new RichTextBox()
    {
        TextWrapping = TextWrapping.Wrap,
        IsReadOnly = true,
    };

    var paragraph = new Paragraph();

    var runs = new List<Inline>();

    foreach (var word in message.Split(' '))
    {
        Uri uri;

        if (Uri.TryCreate(word, UriKind.Absolute, out uri) ||
           (word.StartsWith("www.") && Uri.TryCreate("http://" + word, UriKind.Absolute, out uri)))
        {
            var link = new Hyperlink();
            link.Inlines.Add(new Run() { Text = word });
            link.Click += (sender, e) =>
            {
                var hyperLink = (sender as Hyperlink);
                new WebBrowserTask() { Uri = uri }.Show();
            };

            runs.Add(link);
        }
        else
        {
            runs.Add(new Run() { Text = word });
        }

        runs.Add(new Run() { Text = " "});
    }

    foreach (var run in runs)
        paragraph.Inlines.Add(run);

    textBlock.Blocks.Add(paragraph);

    MessagesListBox.Children.Add(textBlock);
    MessagesListBox.UpdateLayout();
}
