Linq 通过反射动态查询对象

public IQueryable<TEntity> Find<TEntity>(TEntity obj) where TEntity : class

 BindingFlags.Instance);
            //构造初始的query
            IQueryable<TEntity> query = this.GetTable<TEntity>().AsQueryable<TEntity>();
            //遍历每个property
            foreach (PropertyInfo p in properties)

<TEntity, bool>>(filter, param);
                            query = query.Where(pred);
                        }
                    }
                }
            }
            return query;
        }

 

调用：

            Customer c = new Customer();
            c.City = "London";
            c.Phone = "23236133";

            var q = db.Find<Customer>(c).ToList();
