Yes you can, if you have an object array. since
System.Object is the base class of all other types, an item
in an array of Objects can have a reference to any other
type of object.
Is This Answer Correct ?    19 Yes 1 No

What payal has mentioned is absolutely right. Array doesnt
store different datatypes. but ArrayList can store
different types of datatype in a single object.

# 8
no..we cant ..only similar data types in an array.
but we can store in ArrayList
Is This Answer Correct ?    5 Yes 3 No
# 9

Is This Answer Correct ?    2 Yes 0 No
# 10
Ok, so here is the catch:

An array of objects can store different datatype members -
object[] ar = new object[3];
ar[0] = "test";
ar[1] = 56;

An arraylist can also be used for this purpose -
ArrayList arr = new ArrayList();

And a generic list too can be used for this purpose -
List<object> llst1 = new List<object>();
Is This Answer Correct ?    2 Yes 1 No
