推荐答案

基本上在ASP.NET用户控件不是设计不同的项目之间重复使用。这就是为什么如果你想拥有可重用的控件比你可以尝试创建您的控件上的CompositeControl或CompositeDataBoundControl基地。在这种情况下，您能够将您到类库项目控制，然后通过添加引用这个项目（组装）使用这些控件的其他标准服务器控件。在开发复合控件VS用户控件的主要区别是，你需要添加子控件编程，而不是使用标记。但主体是相同的。我建议从阅读一个速成班在ASP.NET控件开发入手：构建复合控制

Basically user controls in ASP.NET are not design to be reused between different project. That's why if you want to have reusable controls than you can try create your controls base on CompositeControl or CompositeDataBoundControl. In this case you will able to place your controls to Class Library project and then use these controls as other standard server controls by adding reference to this project(assembly). The main difference in development composite controls vs user controls is that you need to add child controls programmatically instead of using markup. But the principals are the same. I can advice to start from reading A Crash Course on ASP.NET Control Development: Building Composite Controls
