yes,By explicit interface implementationExample:protected void Page_Load(object sender, EventArgs e){I1 obj1 = new A();I2 obj2 = new A();lblResult1.Text = obj1.Interview();lblResult2.Text = obj2.Interview();}interface I1{string Interview();}interface I2{string Interview();}class A : I1, I2{string I1.Interview(){return "Result2";}string I2.Interview(){return "Result";}}

Interface Interface1 { void Add(); } interface Interface2 { void Add(); }public class Baseclass :interface1,Interface2 { Interface.Add() { console.Writeline(); } Interface.Add() { Console.writeline(); } Public Static Void Main() { baseclass b=new baseclass(); interface1 f1=b; b.add(); interface2 f2=b; b.add(); } }
