Usually when you use Visual Studio to generate some code for you (for data or whatever) it does them as Partial Class ...so you can create another partial class and add your own code to the same class without loosing your changes when the tool regenerates it's code. Long story.
通常，当您使用 Visual Studio 为您生成一些代码（用于数据或其他）时，它会执行它们，Partial Class ...以便您可以创建另一个分部类并将您自己的代码添加到同一个类中，而不会在工具重新生成代码时丢失您的更改。很长的故事。
Anyway, since this is a web site, all files in the folder are part of the project. If you accidently copy the same file twice, it is automatically added and your partial class with the same methods and properties (like NEW) now have multiple definitions.
无论如何，由于这是一个网站，文件夹中的所有文件都是项目的一部分。如果您不小心将同一个文件复制了两次，它会自动添加，并且具有相同方法和属性（如 NEW）的分部类现在有多个定义。
Look for copies of the same classes.
寻找相同课程的副本。
