Say, I have three interfaces:

        public interface I1
        {
            void XYZ();
        }
        public interface I2
        {
            void XYZ();
        }
        public interface I3
        {
            void XYZ();
        }

A class inheriting from these three interfaces:

class ABC: I1,I2, I3
{
      // method definitions
}

Questions:

• If I implement like this:

  class ABC: I1,I2, I3 {

      public void XYZ()
      {
          MessageBox.Show("WOW");
      }
  

  }

It compiles well and runs well too! Does it mean this single method implementation is sufficient for inheriting all the three Interfaces?

• How can I implement the method of all the three interfaces and CALL THEM? I know it can done using explicit implementation but I'm not able to call them. :(
