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>
