ASP. NET Web Pages----Learning Notes (ii)

C # Main Razor syntax rules:

Razor code block by @{...} Surrounded

Inline expression starts at @

The code statement ends with a semicolon

Variables are declared by var keyword

Strings are surrounded by references.

C # code is case sensitive

C # files have the. cshtml extension.

Content block

@RenderPage () import content from a different file

Working with layout pages

@RenderBody ()
The content page must start with the layout directive

Prevent code leaks

In ASP. Files that begin with an underscore name cannot be browsed through the web

Hide sensitive information

In ASP. NET, the usual way to hide sensitive information is to store this information in a separate file called "_appstart".

Asp. NET provides three tools for working with folder paths: The ~ operator, the Server.MapPath method, and the Href method.

~ operator

Specify the virtual root directory in the programming code, use the ~ operator

The Server.MapPath method transforms the virtual path (/default.cshtml) into a physical path that the server can understand.

The href method transforms the path in the code into a path that the browser can understand.

Before Web startup: _appstart

Before each page: _pagestart
