Razor Code Expressions - ( ASP.NET Razor )

ASP.NET Razor is a markup syntax that lets you embed server-based code into web pages. Razor code expressions let you embed C#/VB code within a Razor view file. These expressions contain very small blocks of C#/VB code that execute when the Razor view is rendered.

Syntax

Razor code expressions begin with the @ character followed by the variable or expression you want to render. It is enclosed within parenthesis '()'. 

<p>Total value : @(var1 * var2)</p>

Example

Here is a simple Razor code expression that assigns two variables and calculates their sum:

<p>The sum of 10 and 20 is: @(10 + 20)</p>

You can also use Razor expressions to conditionally render content on a page. For example:

@if (someCondition) {
    <p>This content is only displayed if someCondition is true.</p>
}

Output

Razor code expressions are compiled into HTML and displayed in the web page. The output of the Razor expression is rendered as text within the HTML page.

For Example, if you have a razor code expression:

<p>The sum of 10 and 20 is: @(10 + 20)</p>

then the output generated on the page would be:

<p>The sum of 10 and 20 is: 30</p>

Explanation

Razor code expressions let you embed server-side code within a web page. When the Razor view is rendered, the code is executed and the output is inserted into the HTML. This makes it possible to dynamically generate content and perform logic on the server side. Razor expressions are typically used to display values of variables or to conditionally render content on a page.

Use

Razor code expressions are useful for integrating server-side logic into your web pages. They make it possible to dynamically generate content and perform logic on the server side. This makes it easier to create more interactive and responsive web applications.

Important Points

  • Razor code expressions begin with the @ symbol.
  • Expressions are enclosed in ( )
  • Razor expressions let you embed server-side code within a web page.
  • Expressions can also be used to conditionally render content on a page.
