Different behaviour of method overloading in C#
- by Wondering
Hi All,
I was going through C# Brainteasers(http://www.yoda.arachsys.com/csharp/teasers.html) and came accross one question:what should be the o/p of below code
class Base
{
public virtual void Foo(int x)
{
Console.WriteLine ("Base.Foo(int)");
}
}
class Derived : Base
{
public override void Foo(int x)
{
Console.WriteLine ("Derived.Foo(int)");
}
public void Foo(object o)
{
Console.WriteLine ("Derived.Foo(object)");
}
}
class Test
{
static void Main()
{
Derived d = new Derived();
int i = 10;
d.Foo(i); // it prints ("Derived.Foo(object)"
}
}
but if I change the code to
enter code here class Derived
{
public void Foo(int x)
{
Console.WriteLine("Derived.Foo(int)");
}
public void Foo(object o)
{
Console.WriteLine("Derived.Foo(object)");
}
}
class Program
{
static void Main(string[] args)
{
Derived d = new Derived();
int i = 10;
d.Foo(i); // prints Derived.Foo(int)");
Console.ReadKey();
}
}
I want to why the o/p is getting changde when we are inheriting vs not inheriting , why method overloading is behaving differently in both the cases
