As we know array is a collection of similar objects.

If we create array of integer, we can pass or assign only the integer values. If we try to pass or assign any other data type value we will get a compile time error.

So, how can we store values of different data types in a single array?

We can create array of object.

As we know all types i.e. value types and complex types directly or indirectly inherits from System.Object namespace. So, we can pass any type of data to an object type.

DEMO

  1. using System;
  3. namespace ObjectArrays
  4. {
  5. class Student
  6. {
  7. public int Id{get;set;}
  8. public string Name{get;set;}
  9. public override string ToString()
  10. {
  11. return this.Name;
  12. }
  13. }
  14. class Program
  15. {
  16. static void Main(string[] args)
  17. {
  18. //create an array of type object
  19. object[] ObjectType = new object[3];
  20. //in the first position, we are assigning an integer value
  21. ObjectType[0] = 1;
  22. //in the second position, we are assigning a string value.
  23. ObjectType[1] = "Hello";
  25. Student s = new Student();
  26. s.Id = 1;
  27. s.Name = "Sam";
  29. //in the third position we are assigning a complex value
  30. ObjectType[2] = s;
  32. foreach(object objects in ObjectType)
  33. {
  34. Console.WriteLine(objects);
  35. }
  36. }
  37. }
  38. }
Run the application.
