csharp AutoMapper: Update property values without creating a new object


Normally, we use AutoMapper to Map object like this:

       (cfg) =>
            cfg.CreateMap<TSource, TTarget>();
target = Mapper.Map<TTarget>(source);

however, this will create a new instanse of TTarget, then the reference of target would be changed. The original object of target will not change in this case. The solution is as follows:

Mapper.Map(source, target);
