枚举的简单使用

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

//获取枚举的值（未赋初值）

sex mySex = sex.female;

int mySexValue = (int)mySex;

//获取枚举的值（已赋初值）

state myState = state.unline;

int myStateValue = (int)myState;

//对枚举的值进行递增或递减操作

state myState1 = state.online;

state myState2 = myState1++;

myState2 += 3; //结果为4

}

enum sex { male, female }

enum state { online=1, unline=2 }

enum lenth : long { a,b,c}

}
