How to associate constants with an interface in C#?

Question

Some languages let you associate a constant with an interface:

• A Java example
• A PhP example

The W3C abstract interfaces do the same, for example:

// Introduced in DOM Level 2: interface CSSValue {    // UnitTypes   const unsigned short      CSS_INHERIT                    = 0;   const unsigned short      CSS_PRIMITIVE_VALUE            = 1;   const unsigned short      CSS_VALUE_LIST                 = 2;   const unsigned short      CSS_CUSTOM                     = 3;    attribute DOMString       cssText;   attribute unsigned short  cssValueType; }; 

I want to define this interface such that it can be called from C#.

Apparently C# cannot define a constant associated with an interface.

• What is the usual way to translate such an interface to C#?
• Are there any 'canonical' C# bindings for the DOM interfaces?
• Although C# cannot, is there another .NET language which can define constants associated with an interface?

Answer 1

I added a Get only property and backed it up with a const in the definition.

public interface IFoo {     string ConstValue { get; } }  public class Foo : IFoo {     public string ConstValue => _constValue;     private string _constValue = "My constant"; }
