In this article I am trying an alternative
approach for Multiple Inheritance.
In C sharp Multiple Inheritance is not possible to achieve this is well known.
i.e. You cannot inherit from two classes.
Program : ClassA , ClassB // This cannot be achieved
{
}
So lets try an alternative approach where we can leverage the advantages of
Multiple Inheritance . Please note that I have not used Reflection in this
example , that is not the scope of this article .
Consider ClassA and ClassB as the two classes whose functionality we need to
access .
class ClassA
{
public string
member { get; set;
}
public ClassA()
{
Console.WriteLine("A
constructor is called");
member = "Member of ClassA";
}
public void
display()
{
Console.WriteLine("Display
A");
}
}
class ClassB
{
public string
member { get; set;
}
public ClassB()
{
Console.WriteLine("B
constructor is called");
member = "Member of ClassB";
}
public void
display()
{
Console.WriteLine("Display
B");
}
}
Creating a Router :
Let us create a Router Interface .
interface IRouter
{
void display(string
param);
}
The Router class looks as follows :
class Router : IRouter
{
public string
member { get; set;
}
public Router(string
param)
{
if (param ==
"A")
{
new
ClassA();
member = new ClassA().member;
}
else if
(param == "B")
{
new
ClassB();
member = new ClassB().member;
}
}
public void display(string
param)
{
if (param ==
"A")
{
new
ClassA().display();
}
else if
(param == "B")
{
new
ClassB().display();
}
}
}
class Program
{
static void
Main(string[] args)
{
IRouter router =
new Router("A");
router.display("B");
Console.Read();
}
}
The following output is displayed :
Conclusion
This is a simple Router which routes the method calls to Respective classes
based on the User Input. Hopefully it would be useful. Thanks .
