Object Oriented Programming using C#
Inheritance and Method Overriding
Thus directly, or indirectly, all classes created in C# inherit the ToString() method defined in the Object class.
3.11 Overriding ToString() defined in ‘Object’
The Object class defines a ToString() method, one of several useful methods.
ToString() has the signature
public String ToString()
The purpose of the ToString() method is to return a string value that represents the current object. The version of ToString()
defined by Object produces output like: “Book”. This is the class name from which an object is instantiated. However to
be generally useful we need to override this to give a more meaningful string.
In Publication
public override String ToString()
{
return title;
}In Book
public override String ToString()
{
return base.ToString() + “ by “ + author;
}
