ASP.NET - Directives

In ASP.NET, directives are special instructions that are used to provide instructions to the compiler or the runtime. Directives are special instructions that are processed by the ASP.NET page framework before the page is compiled or executed. Here are some common ASP.NET directives:

• Page directive - The @Page directive is used to define page-specific attributes. It is usually the first directive in an ASP.NET page and can be used to specify page attributes such as the language used, the master page, and the page title.
• Assembly directive - The @Assembly directive is used to specify the assembly that contains the classes used in the page. This is useful when using custom server controls or when referencing external libraries.
• Import directive - The @Import directive is used to import namespaces into an ASP.NET page. This is useful when working with user-defined classes or libraries.
• Control directive - The @Control directive is used to create a custom server control. It allows you to define a custom control that can be used in other pages.
• Output Cache directive - The @OutputCache directive is used to specify how a page should be cached. This directive can be used to improve the performance of an ASP.NET application by reducing the number of requests made to the server.
• Master directive - The @Master directive is used to define a master page for the current content page. It specifies the layout and structure of the page.
• PreviousPageType directive - The @PreviousPageType directive is used to define the type of the previous page in a cross-page posting scenario. This directive is used to access controls on the previous page.

These are some of the commonly used ASP.NET directives. By using these directives, you can customize the behavior of your web pages and control how they are executed or compiled.
