声明一个枚举类型，与struct的区别是：枚举里的变量都是整型的同类型，而struct是由不同类型的变量所组成的，默认情况下，枚举的第一个值为0，后面每个连续的元素值递增1。
1 public struct ProductType 2 { 3 public const string JOURNAL ="JOURNAL"; 4 public const string AUTHOR = "AUTHOR"; 5 public const string ORGAN = "ORGAN"; 6 public const string PUBLISHER = "PUBLISHER"; 7 public const string AREA = "AREA"; 8 public const string FUND = "FUND"; 9 public const string SUBJECT = "SUBJECT"; 10 }
1 enum WeekDay 2 { 3 Sunday, 4 //Sunday = 1, 也可以直接赋值 5 Monday, 6 Tuesday, 7 Wednesday, 8 Thursday, 9 Friday, 10 Saturday 11 };
