Hi Guys
NP62 Method call
When you call the method, however, the arguments you send to it must match in both number and type with the arguments listed in the method declaration. This is a guide line has to follow in initiating a method call.
I got the following program from the website.
http://www.java2s.com/Tutorial/CSharp/0060__Operator/TypeoperatorsIs.htm
In the program
Test("Test", new Paper(),
new NonPrintablePaper());
is calling
Test(string sister, params object[] papers).
But it is not meeting the above guide line. Anyone knows please explain the reason.
Thank you
using System;
interface Printable
{
void print(string name);
}
class Paper : Printable
{
public void print(string name)
{
Console.WriteLine("Poking {0}", name);
}
}
class NonPrintablePaper
{
}
class MainClass
{
public static void Test(string sister, params object[] papers)
{
foreach (object o in papers)
{
if (o is Printable)
{
Printable p = (Printable)o;
p.print(sister);
}
}
}
public static void Main()
{
Test("Test", new Paper(), new NonPrintablePaper());
}
}
/*
Poking Test
*/
