C#获取当前枚举类型的基础类型

要返回当前枚举类型的基础类型，代码如下：

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("\nListing 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); } } }

输出结果

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

让我们看另一个例子-

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("\nListing 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); } } }

输出结果

这将产生以下输出-

Not an enum! System.ArgumentException
