Chapter 12 Quick Reference

To	Do this
Create a derived class from a base class	Declare the new class name followed by a colon and the name of the base class. For example: class Derived : Base  {      ...  }
Call a base class constructor	Supply a constructor parameter list before the body of the derived class constructor. For example: class Derived : Base  {      ...      public Derived(int x) : Base(x)      {          ...      }      ...  }
Declare a virtual method	Use the virtual keyword when declaring the method. For example: class Mammal  { public virtual void Breathe()  {       ...  } ... }
Declare an interface	Use the interface keyword. For example: interface IDemo { string Name();     string Description();  }
Implement an interface	Declare a class using the same syntax as class inheritance, and then implement all the member functions of the interface. For example: class Test : IDemo  {      public string IDemo.Name()      {      ...      }       public string IDemo.Description()       {      ...      }  }
