Replacement for Automapper's ForAllOtherMembers() in C#

Replacement for Automapper's ForAllOtherMembers() in C#

In previous versions of AutoMapper, the ForAllOtherMembers() method was used to map all members of a source object to a destination object that didn't have an explicit mapping. However, starting from AutoMapper 10, this method has been removed and replaced with a new option called IgnoreAllPropertiesWithAnInaccessibleSetter().

The IgnoreAllPropertiesWithAnInaccessibleSetter() method allows you to ignore all properties in the destination object that don't have a public setter. Here's an example of how to use it:

var config = new MapperConfiguration(cfg => { cfg.CreateMap<Source, Destination>() .IgnoreAllPropertiesWithAnInaccessibleSetter(); }); var mapper = config.CreateMapper(); var destination = mapper.Map<Source, Destination>(source);

In this example, we are creating a mapping between Source and Destination objects and using the IgnoreAllPropertiesWithAnInaccessibleSetter() method to ignore any properties in the destination object that don't have a public setter.

Alternatively, you can use the ForMember() method with the Condition() method to apply a specific condition to each member that is being mapped. Here's an example:

var config = new MapperConfiguration(cfg => { cfg.CreateMap<Source, Destination>() .ForMember(dest => dest.MyProperty, opt => opt.MapFrom(src => src.MyProperty)) .ForMember(dest => dest.MyOtherProperty, opt => opt.MapFrom(src => src.MyOtherProperty)) .ForMember(dest => dest.MyThirdProperty, opt => opt.Ignore()) .ForMember(dest => dest.MyFourthProperty, opt => opt.Condition(src => src.MyFourthProperty != null)); }); var mapper = config.CreateMapper(); var destination = mapper.Map<Source, Destination>(source);

In this example, we are using the ForMember() method to specify how each member should be mapped. The Ignore() method is used to ignore a specific member, and the Condition() method is used to apply a condition to a specific member.
