What's the best practice to code shared enums between classes

Question

namespace Foo
{
    public enum MyEnum
    {
        High, Low
    }

    public class Class1
    {
        public MyEnum MyProperty { get; set; }
    }
}

MyEnum is declared outside Class1 cause I need it here and in other classes

Seems good, but what if I decide later to delete the file containingClass1?

MyEnum declaration will be lost!!

What's the best practice to code shared enums between classes?

Answer 1

The best practice is creating separate file for each class, enum, or other type.

MyEnum.cs

namespace Foo
{
    public enum MyEnum
    {
        High, 
        Low
    }
}

Class1.cs

namespace Foo
{
    public class Class1
    {
        public MyEnum MyProperty { get; set; }
    }
}

Have your enumerations each in a file of its own, with the same name as the enumeration.

// Foo\MyEnum.cs
namespace Foo
{
    public enum MyEnum
    {
        High, Low
    }
}
