csharpserver side programmingprogramming
获取当前枚举类型的成员名称，代码如下 −
示例
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("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
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 {
Vehicle v = Vehicle.Bike;
Type type = v.GetType();
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("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[] Listing constants .. Car Bus Bike airplane
