Conditionally mapping one source type to two destination types

Question

I have a source DTO like this

public class Member 
{
    public string MemberId {get;set;}
    public string MemberType {get;set;}
    public string Name {g

For version 5 and above you could try below code:

using System;
using AutoMapper;

namespace AutoMapOneToMulti
{
    class Program
    {
        static void Main(string[] args)
        {
            RegisterMaps();

            var s = new Source { X = 1, Y = 2 };

            Console.WriteLine(s);
            Console.WriteLine(Mapper.Map(s));
            Console.WriteLine(Mapper.Map(s));

            Console.ReadLine();
        }
        static void RegisterMaps()
        {
            Mapper.Initialize(cfg => cfg.AddProfile());
        }
    }
    public class GeneralProfile : Profile
    {
        public GeneralProfile()
        {
            CreateMap();
            CreateMap();
        }
    }
    public class Source
    {
        public int X { get; set; }

        public int Y { get; set; }

        public override string ToString()
        {
            return string.Format("Source = X : {0}, Y : {1}", X, Y);
        }
    }
    public class Destination1
    {
        public int X { get; set; }

        public int Y { get; set; }
        public override string ToString()
        {
            return string.Format("Destination1 = X : {0}, Y : {1}", X, Y);
        }
    }
    public class Destination2
    {
        public int X { get; set; }

        public int Y { get; set; }
        public override string ToString()
        {
            return string.Format("Destination2 = X : {0}, Y : {1}", X, Y);
        }
    }
}

And for version below 5 you could try this:

using System;
using AutoMapper;

namespace AutoMapOneToMulti
{
    class Program
    {
        static void Main(string[] args)
        {
            RegisterMaps();

            var s = new Source { X = 1, Y = 2 };

            Console.WriteLine(s);
            Console.WriteLine(Mapper.Map(s));
            Console.WriteLine(Mapper.Map(s));

            Console.ReadLine();
        }
        static void RegisterMaps()
        {
            Mapper.Initialize(cfg => cfg.AddProfile());
        }
    }
    public class GeneralProfile : Profile
    {
        protected override void Configure()
        {
            CreateMap();
            CreateMap();
        }
    }
    public class Source
    {
        public int X { get; set; }

        public int Y { get; set; }

        public override string ToString()
        {
            return string.Format("Source = X : {0}, Y : {1}", X, Y);
        }
    }
    public class Destination1
    {
        public int X { get; set; }

        public int Y { get; set; }
        public override string ToString()
        {
            return string.Format("Destination1 = X : {0}, Y : {1}", X, Y);
        }
    }
    public class Destination2
    {
        public int X { get; set; }

        public int Y { get; set; }
        public override string ToString()
        {
            return string.Format("Destination2 = X : {0}, Y : {1}", X, Y);
        }
    }
}

If you want a dynamic function, use this extension:

public static dynamic DaynamicMap(this Source source)
{
    if (source.X == 1)
        return Mapper.Map(source);
    return Mapper.Map(source);
}

Console.WriteLine(new Source { X = 1, Y = 2 }.DaynamicMap());
Console.WriteLine(new Source { X = 2, Y = 2 }.DaynamicMap());
