Find Tips to program in ASP.NET using Razor

Use @ character before code block:

Before every Razor code block use the @ character


@{ var Number = 123; }
@{ var Literal_String = "Hello World"; }

Use @ character before a variable:

You should use the @ character for the variables you use in the inline expression.

<p>The value of number is: @Number</p>
<p>Your string is : @Literal_String</p>

Enclose code blocks in braces:

As in the first example you should write code inside the curly braces

@{
    var Number = 123;
    var Literal_String = "Hello World";
}
<p>Number and string: @Number and @Literal_String</p>

Inside a block, you end each code statement with a semicolon:

As like asp.net the codes should be end with semicolon

@{
    var Number = 123;
    var Literal_String = "Hello World";
}

Inline expression don't need semicolon:

Code inside the HTML tags don't need any semicolon

<p>The number is: @Number</p>

Use variables to store values:

We can store any datatype into a variable created using var keyword


@{ var Today_Date = DateTime.Now; }

Razor Code is case sensitive:

Razor is case sensitive so the name's with small letters differ from capitals.

@{
    var Number = 12;
    var number = 23;
}

in the above example both are different variables

Strings that contains a backslash, double quotation marks, uses a verbatim(@) symbol.

If you're using backslash(\) or double quotation marks in code block should be started with the @ character

@{ var Folder_Name = @"C:\MyFolder\"; }

@{ var Using_Double_Quote = @"The person said: ""Hello, today is Monday."""; }

Comments:

Razor uses @* for start of a command and *@ for end a command. It can be used for both single line and multiple line commands
@* command example *@
