im beginner and didnt know what to do

推荐答案

最好的要做的事情是离开这个项目，重新开始。 Visual Studio自动生成的代码是有原因的。您仍然可以关注视频，只需保留命名空间即可。如果您注意到 webform2 的定义被声明为

The best thing to do is throw this project away and start again. The code that is auto-generated by Visual Studio is there for a reason. You can still follow the video, just leave the namespace as it is. If you notice the definition of your webform2 is declared as

public partial class webform2 : System.Web.UI.Page

关键点是单词 partial ，表示类定义的某些部分存在于另一个文件中，该文件仍然具有名称空间宣言。除非你真的理解所有部分是如何组合在一起的，否则最好不要尝试改变它。

The key point being the word partial which indicates that some part of the class definition exists in another file, which will still have the namespace declaration. Unless you really understand how all the pieces fit together it is best not to try changing it.
