using System;NChain provides a similar though more robust architecture:
using System.Collections;
namespace Chain_of_responsibility
{
public interface IChain
{
bool Process(object command);
}
public class Chain
{
private ArrayList _list;
public ArrayList List
{
get
{
return _list;
}
}
public Chain()
{
_list = new ArrayList();
}
public void Message(object command)
{
foreach ( IChain item in _list )
{
bool result = item.Process(command);
if ( result == true ) break;
}
}
public void Add(IChain handler)
{
List.Add(handler);
}
}
public class StringHandler : IChain
{
public bool Process(object command)
{
if ( command is string )
{
Console.WriteLine("StringHandler can handle this message
: {0}",(string)command);
return true;
}
return false;
}
}
public class IntegerHandler : IChain
{
public bool Process(object command)
{
if ( command is int )
{
Console.WriteLine("IntegerHandler can handle this message
: {0}",(int)command);
return true;
}
return false;
}
}
class TestMain
{
static void Main(string[] args)
{
Chain chain = new Chain();
chain.Add(new StringHandler());
chain.Add(new IntegerHandler());
chain.Message("1st string value");
chain.Message(100);
}
}
}
