我有两个实体权限和访问权限

Access.cs

public class Access
{
    public int Id { get; set; }

    public string Name { get; set; }

    public List<Permission> PermissionList { get; set; }
}

Permission.cs

public class Permission
{
    public int Id { get; set; }

    public string Name { get; set; }

    public int ParentId { get; set; }

    [NotMapped]
    public bool HasChildren { get; set; }

    [NotMapped]
    public List<Permission> ChildPermissions { get; set; }
}

我还有GenericRepository类来过滤我的数据库中的记录.

GenericRepository.cs

 public virtual IEnumerable<TEntity> Get(
            Expression<Func<TEntity, bool>> filter …

在第249行有skeleton.at(yaxis,xaxis + 1).当我在我的项目中键入此代码时出现此错误:
