You can use the if statement in your Razor code pretty much the same way you would in regular C# code — just prefix the keyword with the “@“ sign:

@{
  int value = 4;
}

@if (value % 2 == 0)
{
  <p> The value is even!</p> 
}

When writing if/else statements, we don’t need to prepend the else if or else lines with an “@“ sign:

@if (value % 2 == 0)
{
  <p>The value was even.</p>
}
else if (value >= 1337)
{
  <p>The value is large.</p>
}
else
{
  <p>The value is odd and small.</p>
}

Instructions

Let’s imagine we’re at a stoplight and we want to display a message depending on the color of the streetlight.

Below the commented line in the code editor, open a code block and create a variable of type string called stopLight. Assign it to the string "green".

Open an if statement and check if the stopLight is green if so, display an <h5> heading, with the message: The stoplight is green, go!.

Write an else if statement, check if the stopLight is red and if so, display an <h5> heading, with the message: The stoplight is red, stop!

Make sure to change the variable stopLight to ensure the case works!

Write another else if statement to check if the stopLight is yellow and if so, display an <h5> heading, with the message: The stoplight is yellow, slow down!

Make sure to change the variable stopLight to ensure the else case works!

For the last else of the series of if/else statements, display an <h5> heading with the message: That stoplight doesn't exist!

Make sure to change the variable stopLight to a string that is not “green”, “yellow”, or “red” to ensure the else case works!
