ASP.NET页面生命周期解释

Question

前段时间的一次采访中，我被要求解释 ASP.NET 页面生命周期。我确实向他解释了，但他对我的回答不满意。有人可以向我解释一下生命周期吗？

Answer 1

ASP.NET 页面生命周期共有 10 个事件，顺序为：

1. Init
2. Load 视图状态
3. Post back data
4. Load
5. Validate
6. Events
7. Pre-render
8. Save view state
9. Render
10. Unload

下面是 ASP.NET 页面生命周期的示意图。在这种情况下预计会有大量代码。我建议您阅读我在 ASP 上写的这篇文章.NET 页面生命周期，详细解释了 10 个事件中的每一个事件以及何时使用它们。

这个缩写词可能会帮助您记住我在下面的博客文章中写到的 ASP.NET 生命周期阶段。
