Implementing an Interface at Runtime

Question

Is it possible to make an already compiled class implement a certain interface at run time, an example:

public interface ISomeInterface {
    void SomeMethod         


        

Answer 1

Well almost. You can use impromptu-interface.

Basic example from https://github.com/ekonbenefits/impromptu-interface/wiki/UsageBasic :

using ImpromptuInterface;

public interface ISimpleClassProps
{
  string Prop1 { get;  }
  long Prop2 { get; }
  Guid Prop3 { get; }
}

var tAnon = new {Prop1 = "Test", Prop2 = 42L, Prop3 = Guid.NewGuid()};
var tActsLike = tAnon.ActLike();
