C# switch

Switch是一个选择语句，根据与要计算的表达式/值匹配的值选择switch case部分。 1如果case语句都不匹配switch变量的值，则选择默认路径。 switch语句就像一组if statements 。我们break从交换机退出。

例

public enum Colors { Red, Blue, Green, Orange }

 Colors myColor;

 ... myColor is set to one of the enum values ...

 switch(myColor){
  case Colors.Red:
    Console.WriteLine("How you like them apples?");
    break;
  case Colors.Blue:
    Console.WriteLine("Ice Ice Baby...");
    break;
  case Colors.Green:
    Console.WriteLine("Fore!");
    break;
  default:
    Console.WriteLine("I have a hard time when I try to rhyme.");
 }

输出

If myColor is Colors.Red:
> How you like them apples?

If myColor is Colors.Blue:
> Ice Ice Baby...

If myColor is Colors.Green:
> Fore!

If myColor is Colors.Orange:
> I have a hard time when I try to rhyme.
