.net – <％#％>和<％=％>有什么区别？

<％#％>在DataBinding阶段被调用.

<％=％>用于从代码到UI层获取值.倾向于与ASP应用程序向后兼容.不应该在.NET中使用.

<％@％>代表directives,允许行为设置而不诉诸代码.

<％：％> (在ASP.NET 4中引入)与％=相同,但是添加了HtmlEncoding功能的输出.意图是使它成为默认使用(超过％=)以帮助屏蔽脚本注入攻击.

Directives specify settings that are
used by the page and user-control
compilers when the compilers process
ASP.NET Web Forms pages (.aspx files)
and user control (.ascx) files.

ASP.NET treats any directive block
(<%@ %>) that does not contain an
explicit directive name as an @ Page
directive (for a page) or as an @
Control directive (for a user
control).
