我正在使用ModernUI来开发WPF应用程序。它包含一个名为链接的控件，可用于浏览页面。它也用于Tab控件，用于在多个选项卡上显示页面（每个选项卡用作链接）。
我的要求是动态生成标签，但在每个标签中我必须显示相同的内容（相同的用户控件）。
设置链接内容的唯一方法是通过Source属性接受类型为URI的对象。
假如我创建5个标签（5个链接）并为每个标签设置相同的URI，则UserControl对象在标签之间共享。（如果我在1个标签上进行更改，则会反映在所有其他标签上）
我应该如何防止这种情况？有没有办法可以将Runtime对象用作URI？
如果可以使用其他替代方法完成任何建议，欢迎提出建议吗？
谢谢！

如果您确实有五个不同的标签，那么按照设计，您应该使用五种不同的来源。如果您想最初拥有相同的内容，则应创建五个Uri类型对象的不同实例，这些实例对应于五个Link s。
除此之外，您还必须确保所有Uri不要指向同一件事。如果他们这样做，改变同样的事情将反映在所有这些标签上。

这是我为我的原因修改的 TabItem模板。希望它对其他人也有好处....
