1.新建控制臺程序
2.NuGet添加entity framework
3.添加數(shù)據(jù)庫HelloEFDb.mdf
4.編碼
class Program
{
static void Main(string[] args)
{
HelloDbContext context = new HelloDbContext();
var p1 = new Person() { Id = 1, Name = "Jim" };
var p2 = new Person() { Id = 2, Name = "Tom" };
context.Persons.Add(p1);
context.Persons.Add(p2);
context.SaveChanges();
}
}
public class HelloDbContext : DbContext
{
private static string _connStr =
@"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=E:\code\gits\EntityFramework6\HelloEF\HelloEFDb.mdf;Integrated Security=True";
public DbSet<Person> Persons { get; set; }
public HelloDbContext():base(_connStr)
{
}
}
public class Person
{
public int Id { get; set; }
public string Name { get; set; }
}
