ValueInjecter question - automapper

Question

After working with AutoMapper I came across ValueInjecter on this site. I am trying it out but I am stuck on what is probably a very simple scenario.
But before I dig into the code sample, does anyone know if ValueInjecter works in a Medium-Trust web environment? (Like Godaddy?)
Ok, onto the code! I have the following models:
public class NameComponent
{
public string First { get; set; }
public string Last { get; set; }
public string MiddleInitial { get; set; }
}
public class Person
{
public NameComponent Name { get; set; }
}
that I want to map to the following DTO:
public class PersonDTO : BaseDTO
{
private string _firstName;
public string FirstName
{
get { return _firstName; }
set { NotifyPropertyChanged(() => FirstName, ref _firstName, value); }
}
private string _middleInitial;
public string MiddleInitial
{
get { return _middleInitial; }
set { NotifyPropertyChanged(() => MiddleInitial, ref _middleInitial, value); }
}
private string _lastName;
public string LastName
{
get { return _lastName; }
set { NotifyPropertyChanged(() => LastName, ref _lastName, value); }
}
}
So when I want to Map from Model to DTO I need a Model.Name.First -> DTO.FirstName
and when going from DTO to Model I need FirstName -> Name.First. From my understanding this is not a simple Flatten/UnFlatten, because the words also reverse themselves, ie: FirstName <--> Name.First. So First and Last names could use the same kind of rule, but what about MiddleInitial? Model.Name.MiddleInitial -> DTO.MiddleInitial.
I see there are some plugins, but none of them seem to do what I would want. Has anyone else come across this scenario?

Answer 1

the basic idea is that I match the Name with the FirstName, I take this as a pivot point, and in the method that usually sets the value to just one (FirstName) property I set it to 3 properties - that's for the FromNameComp
in the ToNameComp i match the same properties but I take the value from 3 and create one and set it
public class SimpleTest
{
[Test]
public void Testit()
{
var p = new Person { Name = new NameComponent { First = "first", Last = "last", MiddleInitial = "midd" } };
var dto = new PersonDTO();
dto.InjectFrom<FromNameComp>(p);
Assert.AreEqual(p.Name.First, dto.FirstName);
Assert.AreEqual(p.Name.Last, dto.LastName);
Assert.AreEqual(p.Name.MiddleInitial, dto.MiddleInitial);
var pp = new Person();
pp.InjectFrom<ToNameComponent>(dto);
Assert.AreEqual(dto.LastName, pp.Name.Last);
Assert.AreEqual(dto.FirstName, pp.Name.First);
Assert.AreEqual(dto.MiddleInitial, pp.Name.MiddleInitial);
}
public class FromNameComp : ConventionInjection
{
protected override bool Match(ConventionInfo c)
{
return c.SourceProp.Name == "Name" && c.SourceProp.Type == typeof(NameComponent)
&& c.TargetProp.Name == "FirstName"
&& c.SourceProp.Value != null;
}
protected override object SetValue(ConventionInfo c)
{
dynamic d = c.Target.Value;
var nc = (NameComponent)c.SourceProp.Value;
//d.FirstName = nc.First; return nc.First does this
d.LastName = nc.Last;
d.MiddleInitial = nc.MiddleInitial;
return nc.First;
}
}
public class ToNameComponent : ConventionInjection
{
protected override bool Match(ConventionInfo c)
{
return c.TargetProp.Name == "Name" && c.TargetProp.Type == typeof(NameComponent)
&& c.SourceProp.Name == "FirstName";
}
protected override object SetValue(ConventionInfo c)
{
dynamic d = c.Source.Value;
var nc = new NameComponent { First = d.FirstName, Last = d.LastName, MiddleInitial = d.MiddleInitial };
return nc;
}
}
public class NameComponent
{
public string First { get; set; }
public string Last { get; set; }
public string MiddleInitial { get; set; }
}
public class Person
{
public NameComponent Name { get; set; }
}
public class PersonDTO
{
public string FirstName { get; set; }
public string MiddleInitial { get; set; }
public string LastName { get; set; }
}
}

does anyone know if ValueInjecter
works in a Medium-Trust web
environment? (Like Godaddy?)
it doesn't use reflection.emit so it should work
