asp.net4.0 All page Instructions

Asp. NET Web page directive (page Directive) is the label declaration at the beginning of the page:

<% page language= "C #"%>

The purpose of the directive is to specify the settings that are used by the Web page and the user control compiler to process the ASP. NET Web Form Web page (. aspx file) and user control (. ascx) files. The following table is all instructions for asp.net4.0.

These directives have specific companion applications, such as the main page, which uses the @master directive, which uses the @previouspagetype directive, which itself contains a lot of attributes, and if you want to learn more, check the MSDN Library online Help file. Fortunately, in most cases, we do not need to manually add these instructions, because Visual Studio joins automatically, but if you encounter situations where you need to manually join yourself, simply query their usage in the online Help file.
