What
is Razor?
Razor is a markup syntax that lets
you embed server-based code (Visual Basic and C#) into web pages.
Server-based code can create dynamic
web content on the fly, while a web page is written to the browser. When a web
page is called, the server executes the server-based code inside the page
before it returns the page to the browser. By running on the server, the code
can perform complex tasks, like accessing databases.
Razor is based on ASP.NET, and
designed for creating web applications. It has the power of traditional ASP.NET
markup, but it is easier to use, and easier to learn.
Razor
Syntax
Razor uses a syntax very similar to
PHP and Classic ASP.
Razor:
<ul>
@for (int i = 0; i < 10; i++) {
<li>@i</li>
}
</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>
<?php
for ($i = 0; $i < 10; $i++) {
echo("<li>$i</li>");
}
?>
</ul>
Web Forms (and Classic ASP):
<ul>
<% for (int i = 0; i < 10; i++) { %>
<li><% =i %></li>
<% } %>
</ul>
<% for (int i = 0; i < 10; i++) { %>
<li><% =i %></li>
<% } %>
</ul>
Razor
Helpers
ASP.NET helpers are components that
can be accessed by single lines of Razor code.
You can build your own helpers using
Razor syntax, or use built-in ASP.NET helpers.
Below is a short description of some
useful Razor helpers:
- Web Grid
- Web Graphics
- Google Analytics
- Facebook Integration
- Twitter Integration
- Sending Email
- Validation
