Question

I have two objects(classes) with exact properties. say :

class class1
{
  public string prop1{get;set;}
  public string prop2{get;set;}
}

class class2
{
    public string prop1{get;set;}
    public string prop2{get;set;}
}

I want to map these classes using reflection, I have already used AutoMapper and it doesn’t work for my situation, as I have object inside object….

When using reflection I need to pass the property name and i don’t want to do this one by one is there other way:

PropertyInfo propinfo = listToReturn.GetType().GetProperty(nameofproperty);

EDIT::

Here is what i have tried with automapper:

 internal static DTO_objectclass  ConvertFOS(objectclass q)
        {
            DTO_objectclass  resultsToReturn = new DTO_objectclass();

            AutoMapper.Mapper.CreateMap<objectclass , DTO_objectclass  >();

            resultsToReturn = AutoMapper.Mapper.Map<objectclass , DTO_objectclass>(q);

            return resultsToReturn;
        }

this works until it comes to a property where I have something like this in objectclass :

property class3 parentClass{get; set;}

and in DTO_objectclass i got :

 property guid parentClass{get; set;}

where i get exception of failed to convert..

Trying to map System.Guid to parentclient.\nUsing mapping configuration for DTO_objectclass   to objectclass \nDestination property: ParentClass\nException of type 'AutoMapper.AutoMapperMappingException' was thrown.

The exception explains the issue. AutoMapper can’t convert a GUID to a ParentClass. AutoMapper will assume that two properties/fields with the same name will be of the same type in the absence of better information.

To overcome this, you’ll need to write a conversion method. If that method were called ConvertGuidToParentClassInstance, for example, you could then write a mapping like this:

Mapper.CreateMap<DTO_objectcass, objectclass>()
  .ForMember(dest => dest.parentClass)
    .MapFrom(src => ConvertGuidToParentClassInstance(src.parentClass));

With such a mapping in place, AutoMapper can handle this case.
