Conversion between ViewModel and Data Transfer Object

Make sure that any property you wish to convert is public (both getter and setter) in your DTO class.

// C# code of DTO class
public class AwesomeTransferDataObject
{
    public string PersonName { get; set; }

    public int PersonAge { get; set; }
}

Mark your ViewModel with the DtoAttribute and use the DTO Type.

Now mark any property you wish to be converted with DtoPropertyAttribute. If both DTO and ViewModel property names are identical, you can omit the propertyName parameter.

// C# code of your ViewModel class
[Dto(typeof(AwesomeTransferDataObject))]
public class AwesomeViewModel : ViewModel
{
    private string _name;

    [DtoProperty]
    public string Name
    {
        get => _name;
        set => SetProperty(ref _name, value);
    }

    private int _age;

    [DtoProperty]
    public int Age
    {
        get => _age;
        set => SetProperty(ref _age, value);
    }
}

Here is an example how conversion can be applied:

// C# code of the conversion
var dto = new AwesomeTransferDataObject { PersonName = "John" };
var viewModel = dto.ToViewModel<AwesomeViewModel>();
if (viewModel.Name == "John")
    viewModel.Age = 33;
var dto2 = viewModel.ToDto<AwesomeTransferDataObject>();
