Solution 1

The function that got implemented is actually the function defined in you class cl. The interface is only providing a template that the class my adhere to.

In this case as you are deriving from 2 interfaces that each have a function with the same signature and therefore fulfilling both interface definitions.

The answer is: both. See here
Unless you implement then explicitely. See here

You can test with

public interface Iname
{
   void display();
}
 
public interface Iname2
{
   void display();
}
 
class Program
{
    static void Main(string[] args)
    {
	cl obj = new cl();
	Iname i1 = obj as Iname;
	i1.display();
	
	Iname2 i2 = obj as Iname2;
	i2.display();		
        System.Console.ReadLine();
    }
}
 
class cl : Iname, Iname2
{
    public void display()
    {
        System.Console.WriteLine("speed is 300");
    }
}
