ASP.NET Razor - Tags

Razor is not a programming language. It is a server-side markup language.

What is Razor?

Razor is a markup syntax that allows you to embed server-based code (Visual Basic and C#) into web pages.

Server-based code creates dynamic web content as the web page is delivered to the browser. When a web page is requested, the server executes the server-based code in the page before returning the page to the browser. Run by the server, the code can perform complex tasks, such as accessing a database.

Razor is based on ASP.NET and is designed for creating web applications. It has the functionality of traditional ASP.NET, but is easier to use and easier to learn.

Razor Syntax

Razor uses a similar syntax to PHP and classic ASP.

Razor:

<ul>
@for (int i = 0; i < 10; i++) {
<li>@i</li>
}
</ul>

PHP:

<ul>
<?php 
for ($i = 0; $i < 10; $i++) {
echo("<li>$i</li>");
} 
?>
</ul>

Web Forms (Classic ASP):

<ul>
<% for (int i = 0; i < 10; i++) { %>
<li><% =i %></li>
<% } %>
</ul>

Razor Helper

ASP.NET Helpers are components accessible with a few lines of simple Razor code.

You can build your own helper using Razor syntax, or use the built-in ASP.NET helper.
