要获取当前枚举类型的成员的名称,代码如下-
using System; public class Demo { enum Vehicle {Car, Bus, Bike} public static void Main() { try { Type type = typeof(string); string[] str = type.GetEnumNames(); Console.WriteLine("GetEnumName() to return the constant name = " + str); Console.WriteLine("Listing constants .."); for (int i = 0; i < str.Length; i++) Console.Write("{0} ", str[i]); } catch (ArgumentException e) { Console.WriteLine("不是枚举!"); Console.Write("{0}", e.GetType(), e.Message); } } }
输出结果
这将产生以下输出-
不是枚举! System.ArgumentException
让我们看另一个例子-
using System; public class Demo { enum Vehicle {Car, Bus, Bike, airplane} public static void Main() { try { Vehicle v = Vehicle.Bike; Type type = v.GetType(); string[] str = type.GetEnumNames(); Console.WriteLine("GetEnumName()返回常量名称 = " + str); Console.WriteLine("列出常量 .."); for (int i = 0; i < str.Length; i++) Console.Write("{0} ", str[i]); } catch (ArgumentException e) { Console.WriteLine("Not an enum!"); Console.Write("{0}", e.GetType(), e.Message); } } }
输出结果
这将产生以下输出-
GetEnumName()返回常量名称 = System.String[] 列出常量 .. Car Bus Bike airplane
