Get the array of the values of the constants in the current enum type in C#
To get the array of the values of the constants in the current enumeration type, the code is as follows −
Example
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("GetEnumNames() to return the constant name = " + str);
Type type2 = type.GetEnumUnderlyingType();
Console.Write("Enum Underlying type = "+type2);
Array arrObj = type.GetEnumValues();
Console.Write("Values = {0}"+arrObj);
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);
}
}
}Output
This will produce the following output −
Not an enum! System.ArgumentException
Example
Let us see another example −
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);
Array arrObj = type.GetEnumValues();
Console.Write("Values = "+arrObj);
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);
}
}
}Output
This will produce the following output −
GetEnumName() to return the constant name = System.String[] Enum Underlying type = System.Int32Values = Demo+Vehicle[] Listing constants .. Car Bus Bike Airplane
