What are the keywords used to pass parameters to
the base class and how do I invoke other constructors.
Answer Posted / radhika
using base keyword we can pass parameters to the baseclass.
When an instance of the DerivedClass is created.The default
constructor in BaseClass is first invoked followed by the
DerivedClass . However, you
can choose which constructor you want to invoke in
BaseClass by using the base keyword in the
default constructor in DerivedClass , like this:
public class BaseClass
{
//---default constructor---
public BaseClass()
{
Console.WriteLine(“Default constructor in BaseClass”);
}
//---parameterized constructor---
public BaseClass(int x)
{
Console.WriteLine(“Parameterized Constructor in BaseClass”);
}
}
public class DerivedClass : BaseClass
{
//---default constructor---
public DerivedClass(): base(4)
{
Console.WriteLine(“Constructor in DerivedClass”);
}
}
