from quickstart:
simplified code behind model new in 2.0
asp.net 2.0 introduces an improved runtime for code-behind pages that simplifies the connections between the page and code. in this new code-behind model, the page is declared as a partial class, which enables both the page and code files to be compiled into a single class at runtime. the page code refers to the code-behind file in the codefile attribute of the <%@ page %> directive, specifying the class name in the inherits attribute. note that members of the code behind class must be either public or protected (they cannot be private).
the advantage of the simplified code-behind model over previous versions is that you do not need to maintain separate declarations of server control variables in the code-behind class. using partial classes (new in 2.0) allows the server control ids of the aspx page to be accessed directly in the code-behind file. this greatly simplifies the maintenance of code-behind pages.
这对开发来说确实是一个改进,codebehind中去掉server control的声明会使代码”清爽”很多，看起来舒服多了。请看示例:
