HttpContext.Current.IsDebuggingEnabled

这对于决定要输出哪些脚本(最小或完整版本)或其他您在开发中可能想要但不是实时的脚本非常有用。

HttpContext。项作为请求级缓存工具

HttpContext.Current will always give you access to the current context's Request/Response/etc., even when you don't have access to the Page's properties (e.g., from a loosely-coupled helper class). You can continue executing code on the same page after redirecting the user to another one by calling Response.Redirect(url, false ) You don't need .ASPX files if all you want is a compiled Page (or any IHttpHandler). Just set the path and HTTP methods to point to the class in the <httpHandlers> element in the web.config file. A Page object can be retrieved from an .ASPX file programmatically by calling PageParser.GetCompiledPageInstance(virtualPath,aspxFileName,Context)

System.Web.VirtualPathUtility

你可以使用ASP。.aspx页面中的。NET注释用于注释掉页面的全部部分，包括服务器控件。而且被注释掉的内容永远不会被发送到客户端。
