数据库生成linq对象工具sqlmetal

喜欢用linq的自己觉得直接在项目中创建linq to sql类,拖来拖去没有技术含量.手动写mapping吧,又觉得累.真是活生生的矛盾体.呵呵..最后微软还是提供了这样的方式,就是利用sqlmetal工具生成mapping.这样就不用自己写重复的代码,针对修改.省事儿还不失技术含量.废话少说,官方介绍:sqlmetal工具介绍

使用心得:

第一步:打开C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin目录,并在地址栏复制路径

第二步:运行cmd.在cmd中打开刚刚复制的目录路径.

第三步:可就要参考msdn了.我的目的是仅仅是生成所有表的mapping,并生成.cs文件.参考命令是:sqlmetal /server:. /database:db_movie /user:sa /password:***** /code:MoviesModels.cs /language:csharp /namespace:Study.Models

大致意思是打开本服务器的db_movie数据库,生成MovieModels.cs的文件,生成语言是c#,命名空间是Study.Model.

好了,在C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin这个目录下就生成了一个MoviesModels.cs的文件,然后将其copy至开发环境.
