New Switch syntax with C# 8.0

Microsoft has launched newer syntax for switch expression starting from C# 8.0. Switch statements must produce a value in each of its case blocks. Switch expressions allow us to use extra compact expression syntax.

With new syntax are fewer repetitive “cases and break” keywords and fewer “curly braces.”

As an example, consider the following enum with a collection of the colors:

public enum Color {
Red,     
Orange,     
Yellow,     
Green,     
Blue,     
Indigo,     
Violet
}

Old switch syntax

switch (c)
{
  case Color.Red:
      Console.WriteLine("The color is red");
      break;
  default:
      Console.WriteLine("The color is unknown.");
      break;
}
