C# Shorthand If...Else

Shorthand If...Else (Ternary Operator)

There is also a shorthand if else, which is known as the ternary operator because it consists of three operands. It can be used to replace multiple lines of code with a single line. It is often used to replace simple if else statements:

variable = (condition) ? expressionTrue :  expressionFalse;

Instead of writing:

int time = 20;
if (time < 18)
{
  Console.WriteLine("Good day.");
}
else
{
  Console.WriteLine("Good evening.");
}

You can simply write:

int time = 20;
string result = (time < 18) ? "Good day." : "Good evening.";
Console.WriteLine(result);

int x = 50;
int y = 10;
 (x  y)
{
  Console.WriteLine("Hello World");
}
