hi try IPerson[] obj = new IPerson[] { new A() new B() }; foreach (IPerson person in obj) { //Process the data } hope this will help you.

Well clearly you can't convert it to an A[] or a B[] since there is no inheritance relationship between A and B. However as both classes implement IPerson you can convert it to an IPerson[] which is more strongly typed than Object[]. Here's the code: using System; interface IPerson { } class A:IPerson {} class B:IPerson {} class C { public Object[] MyMethod() { Object[] obj = new Object[] { new A() new B() }; return obj; } } class Program { static void Main() { C c = new C(); Object[] obj = c.MyMethod(); IPerson[] persons = new IPerson[obj.Length]; for(int i = 0; i // check it worked foreach(IPerson person in persons) Console.WriteLine(person.GetType()); Console.ReadKey(); } } The output is: A B

Hi Here is nice example for collection. You could use try this for Array.
