Under VS2102, in your solution explorer, right click on your project, and select "Add/New Element" (something like this, my VS version is in french..)
在VS2102下,在您的解决方案资源管理器中,右键单击您的项目,然后选择“添加/新元素”(类似这样,我的VS版本是法语..)
Then you might find : C# -> Data -> "Linq to Sql classes" (depending on your Visual studio version i guess) or you can select "Entity Data Model", An assistant should appear to guide you through the rest of the process.
然后你可能会发现:C# - >数据 - >“Linq to Sql classes”(取决于你猜测的Visual Studio版本)或者你可以选择“实体数据模型”,助理应该会引导你完成其余的过程。
In your project classes you should then use your dataModel, and use Linq to make your requests.
在项目类中,您应该使用dataModel,并使用Linq来发出请求。
I don't have everything in mind right now, you should check that tutorial : http://msdn.microsoft.com/en-US/en-en/library/vstudio/bb399182(v=vs.100).aspx
我现在没有想到的一切,你应该检查一下这个教程:http://msdn.microsoft.com/en-US/en-en/library/vstudio/bb399182(v = vs.100).aspx
Hint: the generated model has a partial class for all your table fields, this is usefull for creating another class of the same name to add specific functions, or fields ;)
提示:生成的模型具有所有表字段的部分类,这对于创建另一个具有相同名称的类来添加特定函数或字段非常有用;)
