Can we store different types in an array in C#

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

using System;

namespace ObjectArrays
{
    class Student
    {
        public int Id{get;set;}
        public string Name{get;set;}
        public override string ToString()
        {
            return this.Name;
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            //create an array of type object
            object[] ObjectType = new object[3];
            //in the first position, we are assigning an integer value
            ObjectType[0] = 1;
            //in the second position, we are assigning a string value.
            ObjectType[1] = "Hello";

            Student s = new Student();
            s.Id = 1;
            s.Name = "Sam";

            //in the third position we are assigning a complex value
            ObjectType[2] = s;

            foreach(object objects in ObjectType)
            {
                Console.WriteLine(objects);
            }
        }
    }
}

Run the application.
