Interface Inheritance Naming Conflicts

Suppose you have two interfaces, lets say Interface-IA, Interface-IB & in both you have declared Name as a property as follows.

public interface IA

{

string Name { get; set; }

String Adress { get; set; }

}

public interface IB

{

string Name { get; set; }

}

Now, you write an interface -IC which derives from above 2 Interfaces as below,

public interface IC : IA, IB

{

int Id { get; set; }

}

When you are try to do the following, you will get an error saying 'Ambiguity between IA.Name and IB.Name'. 

class Test

{

    public void GetSomething()

     {

       IC objIc = new IC();

       Textbox1.Text =  objIc.Name();

     }

}

It can be solved by upcasting as below.

class Test

{

  public void GetSomething()

  {

      IC objIc = new IC();

      Textbox1.Text =  ((IA)objIc).Name();

  }

}
