Yes, its possible try the below sample
replace manageAdvertisement with your class

System.Array ar=Array.CreateInstance(Type.GetType
("System.Object"),3);
ar.SetValue("asdfas",0);
ar.SetValue(1, 1);
ManageAdvertisement mg=new ManageAdvertisement();
mg.AdvertisementDesc="123124";
ar.SetValue(mg, 2);

we can do this by declaring object in array which can be
used for different data types!!!

yes,ofcourse
System.Array is of Object Type
eg:
int a =10;
float b=2.03;
string c = "yes"
object[] val = new object[3];
val[0] = a;
val[1] = b;
val[2] = c;

Answer / michael

No you can't ArrayList stores object. So if you use something like this
ArrayList arr = new ArrayList();
arr.Add(56);
arr.Add("ASDf");

you are still storing objects, 56 is object, ASDf is an object

Answer / surya

No you can not. But if you use System.Collection.ArrayList
then you can store multiple data types in ArrayList but not
in case of System.Array.

Answer / srivathsan

i guess you cannot do that in a list too. because an array
list is also type safe.
eg:

List<int> arraylist = new List<int>();

the arraylist can contain only integer items.You cannot
store an item that is not an integer type in the arraylist.
