Evaluate Expressions in Switch Statements in C#

Question

I have to implement the following in a switch statement:

switch(num)
{
  case 4:
    // some code ;
    break;
  case 3:
    // some code ;
    brea         


        

Answer 1

If your num can't be less than zero:

public int GetSwitch(int num) { return num < 0 ? -1 : num; }
switch(GetSwitch(num))
{
case 4: // some code ; break;
case 3:// some code ; break;
case 0: // some code ; break;
case -1 :// some code ; break;
}

If it can, use some other "non-existent" number such as int.MinValue.
