 public enum TestEnum
 {

And I want to retrieve

Answer 1

You can use the System.Enum helpers:

System.Type enumType = typeof(TestEnum);
System.Type enumUnderlyingType = System.Enum.GetUnderlyingType(enumType);
System.Array enumValues = System.Enum.GetValues(enumType);

for (int i=0; i < enumValues.Length; i++)
{
    // Retrieve the value of the ith enum item.
    object value = enumValues.GetValue(i);

    // Convert the value to its underlying type (int, byte, long, ...)
    object underlyingValue = System.Convert.ChangeType(value, enumUnderlyingType);

    System.Console.WriteLine(underlyingValue);
}

Outputs
