asp.net - 为什么将 aspx 代码隐藏文件声明为部分类？

Question

为什么aspx页面的部分类背后的代码？

Answer 1

我会向你推荐这个 MSDN Page (ASP.NET 页面类概述)。

When the page is compiled, ASP.NET generates a partial class based on the .aspx file; this class is a partial class of the code-behind class file. The generated partial class file contains declarations for the page's controls. This partial class enables your code-behind file to be used as part of a complete class without requiring you to declare the controls explicitly.

请参阅此图表:

这样，您就有一个包含逻辑的类和一个包含设计器内容的类。在编译时它是作为一个整体生成的。
