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 ;     break;   case 0:     // some code ;     break;   case < 0:     // some code ;     break; } 

Is it possible to have the switch statement evaluate case < 0? If not, how could I do that?

Answer 1

I know that this topic is pretty old but if someone still looking for the answer now in C# 7 it's possible. Here is an example:

switch (value) {      case var expression when value < 0:          //some code          break;        case var expression when (value >= 0 && value < 5):          //some code          break;       default:          //some code          break; }
