Question

I have following class

public class CVisitor : IVisitor
    {
        public int Visit(Heartbeat element)
        {
            Trace.WriteLine("Heartbeat"); 
            return 1;
        }
        public int Visit(Information element)
        {
            Trace.WriteLine("Information"); 
             return 1;
        }

    }

I want to have a Dictionary with mappings, that every argument type will be mapped to it’s implementation function:Heartbeat will be mapped to public int Visit(Heartbeat element)

I thought to do something like following:

    _messageMapper = new Dictionary<Type, "what should be here ?" >();
    _messageMapper.Add(typeof(Heartbeat), "and how I put it here?" );

what should I put instead “what should be here ?” and “and how I put it here?”

Thanks

Answer 1

new Dictionary<Type, Func<object, int>>();

var cVisitor = new CVisitor();
_messageMapper.Add(typeof(Heartbeat), 
   new Func<object, int>(heartbeat => cVisitor.Visit((Heartbeat)heartbeat)) 
);
