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.");
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 产量
|
|||
|
|
```
|
|||
|
|
If myColor is Colors.Red:
|
|||
|
|
> How you like them apples?
|
|||
|
|
|
|||
|
|
If myColor is Colors.Blue:
|
|||
|

|
|||
|
|
|
|||
|
|
If myColor is Colors.Green:
|
|||
|
|
> Fore!
|
|||
|
|
|
|||
|
|
If myColor is Colors.Orange:
|
|||
