Enum.GetValues Method

Updated: August 2011

Retrieves an array of the values of the constants in a specified enumeration.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

[ComVisibleAttribute(true)]
public static Array GetValues(
	Type enumType
)

Parameters

enumType
Type: System.Type

An enumeration type.

Return Value

Type: System.Array
An Array of the values of the constants in enumType.

ExceptionCondition
ArgumentNullException

enumType is null.

ArgumentException

enumType is not an Enum.

The elements of the array are sorted by the binary values of the enumeration constants (that is, by their unsigned magnitude). The following example displays information about the array returned by the GetValues method for an enumeration that includes a negative, zero, and positive value.

using System;

enum SignMagnitude { Negative = -1, Zero = 0, Positive = 1 };

public class Example
{
   public static void Main()
   {
      foreach (var value in Enum.GetValues(typeof(SignMagnitude))) {
         Console.WriteLine("{0,3}     0x{0:X8}     {1}",
                           (int) value, ((SignMagnitude) value));
}   }
}
// The example displays the following output: 
//         0     0x00000000     Zero 
//         1     0x00000001     Positive 
//        -1     0xFFFFFFFF     Negative

The following example illustrates the use of GetValues.

using System;

public class GetValuesTest {
    enum Colors { Red, Green, Blue, Yellow };
    enum Styles { Plaid = 0, Striped = 23, Tartan = 65, Corduroy = 78 };

    public static void Main() {

        Console.WriteLine("The values of the Colors Enum are:");
        foreach(int i in Enum.GetValues(typeof(Colors)))
            Console.WriteLine(i);

        Console.WriteLine();

        Console.WriteLine("The values of the Styles Enum are:");
        foreach(int i in Enum.GetValues(typeof(Styles)))
            Console.WriteLine(i);
    }
}
// The example produces the following output: 
//       The values of the Colors Enum are: 
//       0 
//       1 
//       2 
//       3 
//        
//       The values of the Styles Enum are: 
//       0 
//       23 
//       65 
//       78
