Automapper how to use IgnoreMap attribute with MemberList.Source option

How to use attribute-based member ignoring (e.g. [IgnoreMap]) in conjunction with the MemberList.Source option in Automapper 9.0? The IgnoreMap attribute seems to be ...ignored - the following example throws:

public class Source
{
    public string PropertyA { get; set; }
    [IgnoreMap]
    public string IgnoredProperty { get; set; }
}

public class Destination
{
    public string PropertyA { get; set; }

    public string PropertyC { get; set; }
}

public class MyProfile : Profile
{
    public MyProfile()
    {
        CreateMap<Source, Destination>(MemberList.Source);
    }
}

when configuring using the MapperConfiguration.AssertConfigurationIsValid(). It throws AssertConfigurationIsValid as if [IgnoreMap] was not there:

Unmapped members were found. Review the types and members below. Add a custom mapping expression, ignore, add a custom resolver, or modify the source/destination type For no matching constructor, add a no-arg ctor, add optional arguments, or map all of the constructor parameters ================================================================== Source -> Destination (Source member list) Mapping.Source -> Mapping.Destination (Source member list)

Unmapped properties: IgnoredProperty

I have also tried [Ignore] [NotMapped] attributes, however the result was the same.

Additional properties in source automatically ignored by mapper ,so you should ignore explicitly ignored properties of destination, so in your case you must do like below code:

CreateMap<Source, Destination>.ForMember(x => x.PropertyC , options => options.Ignore());

i havent tried attribute ignore for automapper, i always use this

CreateMap<Source, Destination>.ForMember(x => x.IgnoredProperty, opt => opt.Ignore());

or try answers here : How to configure Automapper to automatically ignore properties with ReadOnly attribute?
