Code Example1

Person.cs

    public class Person
    {
        public string Address { get; set; }
        public string Email { get; set; }
        public string FirstName { get; set; }
        public Guid Id { get; set; }
        public string LastName { get; set; }
    }

PersonDto.cs

    public class PersonDto
    {
        public string Email { get; set; }
        public string FirstName { get; set; }
        public Guid Id { get; set; }
        public string LastName { get; set; }
    }

Main

        static void Main(string[] args)
        {
            //First of all Bind Person type to PersonDto type and we don't want map Email property. So it has been ignored.
            TinyMapper.Bind<Person, PersonDto>(config => {
                config.Ignore(x => x.Email);
            });

            var person = new Person {
                Id = Guid.NewGuid(),
                FirstName = "Luke",
                LastName = "Chen",
                Email = "xiaoyong6906@126.com"
            };

            //Now TinyMapper knows how to map Person object to PersonDto object. Finally, call
            PersonDto personDto = TinyMapper.Map<PersonDto>(person);
            Console.WriteLine("personDto:" + personDto.Id + personDto.FirstName + personDto.LastName + personDto.Email);
            Console.ReadLine();
        }
