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
