Here's an example which may make these concepts clearer. The Child class inherits from Father but contains Mother: using System; class Father { protected string fatherName; public string FatherName { get{ return fatherName; } } public Father(string name) { this.fatherName = name; } } class Mother { private int numberOfChildren; private string motherName; public string MotherName { get{ return motherName; } } public int NumberOfChildren { get { return numberOfChildren; } } public Mother(string name, int numberOfChildren) { this.motherName = name; this.numberOfChildren = numberOfChildren; } } class Child : Father { private string childName; private int age; private Mother mother; public int NumberOfSiblings { get{ return mother.NumberOfChildren - 1; } } public string MotherName { get{ return mother.MotherName; } } public string ChildName { get { return childName; } } public int Age { get{ return age; } } public Child(string name, int age, Mother mother, string fatherName) : base (fatherName) { this.childName = name; this.age = age; this.mother = mother; } } class Test { static void Main() { Mother m = new Mother("Judy", 3); Child c = new Child("James", 25, m, "Larry"); Console.WriteLine("{0} has {1} siblings", c.ChildName, c.NumberOfSiblings); Console.WriteLine("He is aged {0} and his mother's name is {1}", c.Age, c.MotherName); Console.WriteLine("His father's name is {0}", c.FatherName); Console.ReadKey(); } }

Hi Deepak, Inheritance isn't the same thing as containership. With constainership, you include an object of one class as a private member of another class and then expose the public members of the contained object by wrapping them in public members of the container object. With inheritance, an object not only has its own members but those inherited from its base classes. Broadly speaking, the inherited members behave as though they had been declared in the child class itself. As C# doesn't support multiple inheritance, sometimes you might use the two together. For example, if ideally you would have liked to inherit from two classes, you can instead inherit from one class and then contain an object of the other class.
