获取当前枚举类型的基础类型 C#
要返回当前枚举类型的基础类型,代码如下所示 −
示例
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() to return the constant name = " + str); Type type2 = type.GetEnumUnderlyingType(); Console.Write("Enum Underlying type = "+type2); Console.WriteLine("
Listing constants .."); 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
这将产生以下输出 −
GetEnumName() to return the constant name = System.String[] Enum Underlying type = System.Int32 Listing constants .. Car Bus Bike Airplane
示例
让我们看另一个示例 −
using System; public class Demo { enum Vehicle {Car, Bus, Bike, Airplane} public static void Main() { try { Type type = typeof(int); string[] str = type.GetEnumNames(); Console.WriteLine("GetEnumName() to return the constant name = " + str); Type type2 = type.GetEnumUnderlyingType(); Console.Write("Enum Underlying type = "+type2); Console.WriteLine("
Listing constants .."); 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
这将产生以下输出 −
Not an enum! System.ArgumentException
