推荐答案
据取决于你的质量要求，但在大多数情况下，我会强烈建议您使用实体框架或LINQ to SQL数据类。你会好得多......后者去作为一个开始......希望它帮助。
It depends on your requirments, but for most situations, I would highly recommend you use Entity Framework or Linq to Sql data classes. You'd be much better off... go with the latter as a start... hope it helps.
如果你想看到一个ORM可以多么容易：
If you want to see how easy an ORM can be:
- 在您的项目
- 右键单击选择Add New Item
- 选择的Linq到SQL数据类
- 当您添加它，你就会有一个空白.dbml文件
- 转到服务器资源管理器，并添加连接到SQL数据库
- 拖放任何你喜欢的表
-
开始使用实体是这样的：
- right-click on your project
- select Add New Item
- Choose Linq to Sql Data Classes
- When you've added it, you'll have a blank .dbml file
- Go to server explorer and add a connection to the sql db
- Drag and drop the tables wherever you like
Start using the entities like this:
使用（DataClasses1DataContext DB =新DataClasses1DataContext（数据源= localhost\sqlexpress;初始目录= myDBName;集成安全=真））
{
IEnumerable的citiesForUSA = db.Cities.Where（X => x.Country.Name ==美国）;
using (DataClasses1DataContext db = new DataClasses1DataContext("Data Source=localhost\sqlexpress; Initial Catalog=myDBName; Integrated Security=true")) { IEnumerable citiesForUSA = db.Cities.Where(x => x.Country.Name == "United States");
City city = new City();
city.Name = "Metropolis";
//etc
db.Cities.InsertOnSubmit(city);
db.SubmitChanges(); // <-- INSERT INTO completed
//etc
}
祝你好运！
