automapper - ignore mapping if property type is different with same property name - C#

Question

How can I ignore mapping if property type is different with same property name? By default it\'s throwing error.

Mapper.CreateMap

One way to process all properties for type is to use .ForAllMembers(opt => opt.Condition(IsValidType))). I have used new syntax for AutoMapper usage, but it should work even with old syntax.

using System;
using AutoMapper;

namespace TestAutoMapper
{
    class Program
    {
        static void Main(string[] args)
        {
            var mapperConfiguration = new MapperConfiguration(cfg => cfg.CreateMap()
                .ForAllMembers(opt => opt.Condition(IsValidType))); //and how to conditionally ignore properties
            var car = new Car
            {
                VehicleType = new AutoType
                {
                    Code = "001DXT",
                    Name = "001 DTX"
                },
                EngineName = "RoadWarrior"
            };

            IMapper mapper = mapperConfiguration.CreateMapper();
            var carDto = mapper.Map(car);
            Console.WriteLine(carDto.EngineName);

            Console.ReadKey();
        }

        private static bool IsValidType(ResolutionContext arg)
        {
            var isSameType = arg.SourceType== arg.DestinationType; //is source and destination type is same?
            return isSameType;
        }
    }

    public class Car
    {
        public AutoType VehicleType { get; set; } //same property name with different type
        public string EngineName { get; set; }
    }

    public class CarDto
    {
        public string VehicleType { get; set; } //same property name with different type
        public string EngineName { get; set; }
    }

    public class AutoType
    {
        public string Name { get; set; }
        public string Code { get; set; }
    }
}
