最近在codeplex上找到了一个功能比较全的linq to object 、linq to sql 、linq to entity新增、修改、删除功能扩展的控件——magiq。

　　以linq to sql 为例，

var expiredProducts = store.Query(x => x.Products.Where(y => y.ExpirationDate <= DateTime.Now )).ToList();

//store为相当于数据库一对多的父项，Products相当于子项

products.Where( x=> x.ExpirationDate <= DateTime.Now ).Set( x=> x.State, ProductState.Expired )
                                                      .Set( x => x.Category.HasExpiredProducts,x=>! x.Category.HasExpiredProducts)
                                                      .Update();
//更新操作

store.UpdateCollection( x=> x.Products.Where(y=>y.ExpirationDate <= DateTime.Now ).Set( y=> y.State, ProductState.Expired ));

//一对多时，更新多端的数据

products.Where( x=> x.ExpirationDate <= DateTime.Now ).Delete();
//删除操作

store.DeleteCollection( x=> x.Products.Where(y=>y.ExpirationDate <= DateTime.Now ));

//一对多时，删除多端的数据

baseRecordRepository.BulkInsert( products.Where( x=> x.ExpirationDate <= DateTime.Now )
                                     .Select( new ExpirationRecord { Description = x.Name + " expired" } ));

//批量新增操作，相当于SQL语句：insert into ...select ...

要使用该控件的话，要先 using Magiq;

linq to sql 的话，还需引用MirrorMirror.dll

linq to entity的话，还需引用LinqToEdmx.Core.dll和Xml.Schema.Linq.dll

在调用上述函数前，还需调用Register来表示本次操作是linq to object 、linq to sql 、linq to entity的哪一种操作，

Magiq.MagiqConfigurator.Register(new Magiq.Providers.Sql.MagiqToSql()); //linq to sql

Magiq.MagiqConfigurator.Register(new Magiq.Providers.Objects.MagiqToObjects()); //linq to object

Magiq.MagiqConfigurator.Register(new Magiq.Providers.Entities.MagiqToEntities()); //linq to entity
