泛型方法,获取不明确的调用错误

我正在使用存储库模式,并试图构建一个通用方法,因为我有几个对象以相同的方式从它们的存储库中提取:

我的存储库的创建方式如下:

public interface IEntityRepository<T> : IDisposable

public interface IAuditorRepository : IEntityRepository<Auditor>

public class AuditorRepository : IAuditorRepository

审计员类别定义如下:

public class BaseEntity : IObjectWithState

public partial class Auditor : BaseEntity

除了AuditorRepository,我还有一些其他的,比如BuildingRepository。现在我正在尝试创建一个通用方法,在其中我可以传递Repository:

    public List<EditSelectItemViewModel> GetItems<T>(IEntityRepository<T> repos) where T : BaseEntity 
    {
        var d = repos.All.Where(x => x.isActive).OrderBy(x => x.Name).Include(z => z.Contracts)
            .Select(y => new EditSelectItemViewModel
            {
                Id = y.Id,
                SourceName = y.Name,
                DisplayOnNew = y.DisplayOnNew,
                NumberOfTimesUsed = y.ActiveContracts.Count(a => a.isActive)
            }).ToList();

        return d;
    }

但我一直在上出错。其中指出这是一个模棱两可的引用。所有存储库都实现All方法,例如AuditorRepository版本:

    public IQueryable<DomainClasses.Auditor> All
    {
        get { return _context.Auditors; }
    }

IEntityRepostory定义为:

    public interface IEntityRepository<T> : IDisposable
{
    IQueryable<T> All { get; }
    //List<T> AllRequests { get; }
    IQueryable<T> AllIncluding(params Expression<Func<T, object>>[] includeProperties);
    T Find(params object[] keyValues);
    void InsertOrUpdateGraph(T entityGraph);
    void InsertOrUpdate(T entity);
    void Delete(params object[] keyValues);

}

baseEntity为:

    public class BaseEntity : IObjectWithState
{
    public State State { get; set; }
}

状态定义为:

    public interface IObjectWithState
{
    State State { get; set; }
}
public enum State
{
    Added,
    Unchanged,
    Modified,
    Deleted
}
