In general, creating a new page in VS creates two types of files: one is the suffix. cs and one is. aspx.
Simply put, the. cs file is typically implemented in the inside, and. aspx is the interface effect.
The difference:. cs files are written in. NET code, including methods and fields, and. aspx files are written in HTML code, and then bind the fields in the. cs file.
Contact: Project only. cs files are implemented in the background, and. aspx files can guide customers to use this feature. As you ask questions on Baidu, if you don't have a page (that is, the. aspx interface effect), you don't know where to write the question, and click on what to submit. If you do not have the function of the. cs page, you will not be able to put the question to the Baidu server up.
What is the difference between a. cs file and a aspx.cs file??? What is their role??? What is the role of the ASPX file?
