Objects in C#

A class or struct definition is like a blueprint that specifies what the type can do. An object is basically a block of memory that has been allocated and configured according to the blueprint. A program may create many objects of the same class. Objects are also called instances, and they can be stored in either a named variable or in an array or collection.In an object-oriented language such as C#, a typical program consists of multiple objects interacting dynamically.

example: 

{

    A a=new A(); // object 

   int x=a.m(20,10);

  }

}

public class A  // class

 {

      public int m(int x,int y);  // method( x & y are parameter)

        {

              int z=x+y;

               return z;

        }
}
