推荐答案

Page_Load 是一个事件处理程序它基本上说明了加载页面时会发生什么。 sender 是导致此事件的原因， e 包含有关该事件的信息。例如，如果你从一定高度掉球， Page_Load is an event handler. It basically tells what should happen if a page is loaded. sender is what caused this event and e contains information about the event. For instance, if you drop a ball from certain height, event: you dropping the ball sender: you e: information about the event. Something like from which height you dropped the ball.

基本上，Page_Load函数是一个事件处理程序。 sender是事件引发对象，e变量是事件参数。请查看以下主题： 处理和提升事件 [ ^ ] [ ^ ] 代表（C＃编程指南） [ ^ ] Basicly the Page_Load function is an event handler. The sender is the event raising object, and the e variable is the event arguments. Take a look into the following subjects: Handling and Raising Events[^][^] Delegates (C# Programming Guide)[^]
