我是 ASP.NET MVC 2 的新手。我不明白为什么会收到此错误。是否缺少一些我没有正确引用的东西。

我正在尝试创建一个简单的 jquery 自动完成在线搜索文本框并查看我选择的人的详细信息

为了让文本框搜索显示在索引页面上，我需要做什么？我还需要做什么才能使自动完成功能正常运行。我已将 autocomplete.js 和 jquery.js 添加到 index.aspx 视图中

任何帮助将不胜感激，以便我可以正常工作。

谢谢！

也许这是 global.asax 中路线的顺序？尝试颠倒顺序。我认为它试图从头到尾找到正确的路线，在你的情况下，它总是停在第一条路线，即：“{controller}/{action}/{id}”...
