Razor View Engine in Asp.Net mvc

Razor view engine in asp.net mvc is the syntax that allows you to write server-side code on view. It helps to combine code and HTML in a fluid manner. Razor is not a new programming language. Razor supports C# and Visual Basic programming languages.

The Razor syntax is based on C# programming language and the code statements in Razor end with a semicolon (;) 

Syntax of Razor View Engine

Generally, in razor view engine code blocks are enclosed in "@{ ... }". Here “@” is a character that tells the beginning of Razor syntax. This code can be a single expression or an entire code block. Following syntax represents a razor view engine declaration in asp.net mvc.

@{

//Razor block

}

In the above code, the "@{" character tells the beginning of the block, and the"}" character tells the ending of the block.

Types of Block Statements in Razor

In razor, we have a different type of block statements available. Those are 

1. Single Statement Block and Inline Expression

As we discussed earlier, we will define code in opening and closing curly brackets @{...} and single statement block code will be like as shown following.

@{var Series = 4 ;}

@{var RazorMessage = "Hello Razor";}

<p> MVC series : @Series</p>

<p> Razor Message : @RazorMessage</p>

2. Multiple Statement Block and Inline Expression

In multiple statements block, we will define all variables in single curly brackets @{...}, so we need to end each variable with a semicolon. Our multiple statement block code will be as shown below.

@{

    var Title = "Welcome to Razor syntax!";

    var weekDay = DateTime.Now.DayOfWeek;

    var HomeMessage = Title + " Today is: " + weekDay;

}

<p> Razor Message : @HomeMessage</p>
