[Mono-list] reusing interface implementation

[Michał Ziemski]

Hi!

I would go with something like:
abstract class TestBase {
    astract int x { get; }

  public void iF(){
    Console.WriteLine("x: "+x);
  }    
}

and then make A and B inherit from TestBase.

Alternatively you can do something like:

interface IX { int x { get; } }

class PlusTest<T> : ITest where T : IX {  
  private T val;
  public PlusTest(T val) { this.val = val; }
	
  public void iF(){
    Console.WriteLine("x: "+ val.x);
  }
}
 
Cheers!
