How to use C# switch case statements

The C# switch statement allows you to choose from many statements based on multiple selections by passing control to one of the case statements within its body. The switch statement executes the case corresponding to the value of the expression . The switch statement can include any number of case instances.

  switch (expression)
  {
     case expression:
	    //your code here
	    jump-statement
     default:
	    //your code here
	    jump-statement

}

expression : An integral or string type expression.

jump-statement : A jump statement that transfers control out of the case body.

If any of the expression passed to switch case does not match with case statement the control will go to default: statement . If there is no default: statement control will go outside of the switch statement.
