Given that Automapper 4.2 has marked the static API as obsolete we shouldn’t be using things like Mapper.GetAllTypes() etc. as they will be removed in version 5. A 4.2+ version of a popular extension method for ignoring properties which exist on the destination type but not on the source type is below:
public static IMappingExpression<TSource, TDestination>
IgnoreAllNonExisting<TSource, TDestination>(this IMappingExpression<TSource, TDestination> expression)
{
foreach(var property in expression.TypeMap.GetUnmappedPropertyNames())
{
expression.ForMember(property, opt => opt.Ignore());
}
return expression;
}
Hello, Thanks for the code.
I have written a generic method for mapping.
public static D Map
(S uiSource, D destination) where D : class, new(){
MapperConfiguration config = new MapperConfiguration(cfg =>
{
cfg.CreateMap
().IgnoreAllNonExisting();});
IMapper mapper = config.CreateMapper();
destination = mapper.Map
(uiSource);return destination;
}
public static IMappingExpressionIgnoreAllNonExisting(this IMappingExpression expression)
{
foreach (var property in expression.TypeMap.GetUnmappedPropertyNames())
{
expression.ForMember(property, opt => opt.Ignore());
}
return expression;
}
But this is not working
For Automapper 5.0 use this simple one:
.ForAllOtherMembers(x=>x.Ignore())
works like a charm.
