Question

Given

        List<LabEntity> selected = originalSettings.SelectedInstanceLabs;
        List<LabEntity> available = Presenter.GetLabs(dateRange);
        if (!firstLoad)
        {
            //Remove selected labs from the available labs
            available.Remove(?);// Remove Where selected.Id = available.Id
        }  

Is there an extension method that can complete the task for multiple items? Remove only works on one at a time. The other Remove-type methods don’t seem up to the task either. I could stick a foreach on there, but there’s gotto be a more concise implementation.

Answer 1

Do you mean like this? :

        List<LabEntity> selected = originalSettings.SelectedInstanceLabs;
        List<LabEntity> available = Presenter.GetLabs(dateRange);
        if (!firstLoad)
        {
            //Remove selected labs
            available = available.Except<LabEntity>(selected).ToList();
        }
