问题描述

我想插入我的 UserCompany 对象到数据库trought一个方法。如元素传递给这个函数,把它和插入右表。

I'd like to insert my UserCompany object into the database trought a single method. Such as passing the element to this function, take it and "insert in the right table".

通常在实体(如LINQ到XML)我不喜欢出头:

Usually in Entity (such as LINQ to XML) I do somethings like:

db.Company.UsersCompany.Add(UserCompany);
db.SubmitChanges();

但这里的问题是,我需要指定表 UsersCompany 公司使用前。新增()。我想(因为我想要做一个函数的刀片,每种类型的对象/表)摆脱了这一点。如具有:

but the problem here is that I need to specify the table UsersCompany and Company before using the .Add().I'd like (since I want to do ONE function for the insert for each type of object/table) get rid of this. Such as having a:

UserCompany.InsertMySelf();

db.SmartAdd(UserCompany);

和它知道如何插入表格,在何处以及如何,自动。

and it know how to insert the table, where and how, automatically.

是否有可能这样做吗?有什么策略?

Is it possible to do this? Is there any strategies?

推荐答案

您可以解决这个泛型:

Public Sub AddEntities(Of TEntity)(entities As IEnumerable(Of TEntity))
   For Each ent In entities
       _db.Set(Of TEntity).Add(ent)
   Next
   _db.SaveChanges()
End Sub

抱歉用VB ...   在C#:

Sorry for using VB... In C#:

public void AddEntities<TEntity>(IEnumerable<TEntity> entities)
   {
     foreach(ent in entities)
     {
         _db.Set<TEntity>.Add(ent);
     }
     _db.SaveChanges();
   }
