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();
}

}
Main

TargetClass.cs
public class TargetClass
