An enum in .NET is a structure that maps a set of values (fields) to a basic type (the default is int). Enums are kind of like integers , but you can't rely on their values to always be sequential or ascending. To get all values of an enum, we can use the Enum.GetValues static method.

class EnumLoop {
  enum MyEnum
  {
    High = 10,
    Medium = 5,
    Low = 1
  }
  public static void Main() {
    foreach (MyEnum enumValue in Enum.GetValues(typeof(MyEnum)))
    {
      Console.WriteLine(enumValue);
    }
  }
}

output

Medium
High
Low

The following C# code snippet loops through all values of an enum and prints them on the console.

class EnumLoop {
  enum MyEnum
  {
    High = 10,
    Medium = 5,
    Low = 1
  }
  public static void Main() {
    foreach (int i in Enum.GetValues(typeof(MyEnum)))
    {
      Console.WriteLine($" {i}" );
    }
  }
}

output

      1
      5
      10

Enum.GetValues(Type)

Enum.GetValues(Type) method retrieves an array of the values of the constants in a specified enumeration .

public static Array GetValues (Type enumType);

If multiple members have the same value, the returned array includes duplicate values .
