Example of why I want to ignore item in collection

ExampleIgnoreInCollection.cs

public class ObjectEntity
{
	public int Id { get; set; }
	public bool ReadOnly { get; set; }
	public string SomeDescription { get; set; }
	public double SomeValue { get; set; }
}

public class ObjectDto
{
	public int Id { get; set; }
	public bool ReadOnly { get; set; }
	public string SomeDescription { get; set; }
	public double SomeValue { get; set; }
}

public async Task<List<ObjectDto>> UpdateObjects(List<ObjectDto> dtoObjects)
{
	List<ObjectEntity> objects = await context.Objects.ToListAsync();
	objects = mapper.Map<List<ObjectDto>, List<ObjectEntity>>(dtoObjects, objects);

	context.Objects.UpdateRange(objects);
	await context.SaveChangesAsync();

	List<ObjectEntity> objects = await context.Objects.ToListAsync();
	dtoObjects = mapper.Map<List<ObjectEntity>, List<ObjectDto>>(objects);

	return dtoObjects;
}

public ObjectMappingProfile()
{
	CreateMap<ObjectDto, ObjectEntity>()
		.IgnoreIf((od, oe) => {oe.ReadOnly == true;}) // Fictional function
		.EqualityComparison((od, oe) => od.Id == oe.Id);
}
