你刚刚做了，只要你的表包含两列，并被称为'tblPeople'之类的东西。

您总是可以编写自己的SQL包装器。实际上我更喜欢这样做，我讨厌生成代码，以任何方式。

也许创建一个DAL类，并有一个名为GetPerson(int id)的方法，用于查询数据库中的person，然后从结果集中创建person对象。

最简单的方法是反向工程。http://msdn.microsoft.com/en-US/data/jj593170

Visual Studio杂志发表了这篇文章:

为SQL查询结果生成。net POCO类

它有一个可下载的项目，你可以构建，给它你的SQL信息，它会为你制作出类。

现在，如果该工具刚刚为SELECT、INSERT和UPDATE创建了SQL命令....
