In razor view engine has a different type of block statements are available:-

  •  Single Statement Block
  •  Multiple Statement Block

Single Statement Block and Inline Expression

We define code in opening and closing curly brackets @{...} and single statement block code will be like this 

@{var Series = 4 ;}

@{var RazorMessage = "Hello Razor";}

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

 

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

Multiple Statement Block and Inline Expression

Here, in multiple statement block, we will define all variables in single curly brackets @{...} so we must need to end each variable with a semicolon and our multiple statement block code will be shown like below:- 

 @{

    var Title = "Welcome to Razor syntax!";

    var weekDay = DateTime.Now.DayOfWeek;

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

}

 

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

Usually, in razor engine code written at top of view will be accessible in any other code block in same view page else in case if we will declare a variable in middle and try to access a top we will not be able to access those variables and it will throw an error as it shows:-

We observe in the above code we tried to access variable "i" before declaring that is the reason it throws an error as shown above.
