今天搜索批量删除时，无意间翻到这篇文章感觉思路不错mark一下

相关辅助类可参考原博文


最后的调用：

var filters = new Manager.Models.Filter[]
                {
                    new Manager.Models.Filter {Key = "Phone", Value = "phone", Contract = "like"},
                    new Manager.Models.Filter {Key = "TrueName", Value = "name", Contract = "like"},
                    new Manager.Models.Filter {Key = "IdentityCardId", Value = "identity", Contract = "like"}
                };
qry = db.AppCustomers.Where_And(filters);  //得到最终结果
