Question

我有一个班级人员，其中包含地址和电话列表作为以下代码。在我的查询中，我想要一个人的列表，但不包括已删除的地址和电话，但总是返回所有地址和电话，即使它们标记为已删除。我怎么能用lambda过滤那些嵌套列表？

public class Person{
    public int PersonId { get; set; }
    public string Name { get; set; }      
    public virtual ICollection<Address> Addresses { get; set; }
    public virtual ICollection<Phone> Phones{ get; set; }
    public virtual Company Company { get; set; }
}

public class Address{
    public int AddressId { get; set; }
    public string Street { get; set; }      
    public bool Deleted { get; set; }      
    [ScriptIgnore]
    public virtual Person Person { get; set; }
}

public class Phone{
    public int PhoneId { get; set; }
    public string Number{ get; set; }      
    public bool Deleted { get; set; }      
    [ScriptIgnore]
    public virtual Person Person { get; set; }
}

return GetDbSet<Person>()
    .Include("Address")
    .Include("Phones")
    .Where(i => i.Company.CompanyId == company.CompanyId)
    .OrderByDescending(o => o.CreateTime).ToList();

Answer 1

只需在Where子句中添加条件即可排除已删除的地址和手机，如：

Where(i => i.Company.CompanyId == company.CompanyId &&
           i.Address.Any(r=> !r.Deleted) &&
           i.Phone.Any(r=> !r.Deleted))
