public enum City
{
    HangZhou = 1,
    BeiJing = 0,
    ShangHai = 2,
    ShenZhen = 3
}


//获取ShangHai对应枚举对象
City city_1 = GetEnumByIDorName<City>("ShangHai");
//获取数值3对象的枚举对象
City city_2 = GetEnumByIDorName<City>(3);

Enumerated objects, get the object character and numeric values

string name = city_1.ToString();	//name="ShangHai"
int cnt = (int)city_2;	//cnt=3;
