C# how to use enum with switch

I can't figure out how to use switches in combination with an enum. Could you please tell me what I'm doing wrong, and how to fix it? I have to use an enum to make a basic calculator.

public enum Operator
{
PLUS, MINUS, MULTIPLY, DIVIDE
}

public double Calculate(int left, int right, Operator op)
{

int i = (int) op;

switch(i)
{
case 0:
{
return left + right;
}

case 1:
{
return left - right;
}

case 2:
{
return left * right;
}

case 3:
{
return left / right;
}

default:
{
return 0.0;
}
}
}


The end result should be something like this:

Console.WriteLine("The sum of 5 and 5 is " + Calculate(5, 5, PLUS))
Output: The sum of 5 and 5 is 10


Could you guys please tell me how I'm messing up?

Answer

You don't need to convert it

switch(op)
{
     case Operator.PLUS:
     {

     }
}

By the way, use brackets
