Answer: In C# programming, Array is homogeneous in nature, So, It cannot hold multiple data types e.g. int, String and bool etc. However, by declaring an array as object  can be used to store different data type.
As Object type is the base class of all the data types, if an array is declared as object type then all type of data can be stored in an array.
Strongly Typed or homogenous array will be declared like below syntax. Strongly type array means it can store same type of data only as it has been declared.
int array = new int;
Object type array – C# code example
Hold multiple data types.
static void Main(string args)
//Create an array of object type that
//can store multiple data types
object objAarray = new object;
//Store int type
objAarray = 5;
//Store bool type
objAarray = true;
//Store String type
objAarray = "interviewsansar";
//Read data from array of object type
foreach (Object item in objAarray)
