Hi guys , I came across a piece of code similar to the below one. public partial class Form1 : Form { private void Form1_Load(object sender, EventArgs e) { ad test = new ad(); Ia id5 = test.testobj(); id5.display() } } public interface Ia { void display(); } public class b : Ia { public void display() { MessageBox.Show("do it man"); } } public class ad { public Ia testobj() { b gh = new b(); return gh; } } My question is why should we typecast object gh to interface Ia in testobj() function as the interface object when we can directly use the object of class b to call display function. Thans in advance, sishya -- modified at 5:54 Friday 27th April, 2007
