方法一：使用Attribute
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)
{
}
}
[Table("persons")]
public class Person
{
[Column("person_id")]
public int Id { get; set; }
[Column("person_name")]
public string Name { get; set; }
}
方法二：重寫DbContext.OnModelCreating
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)
{
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
//base.OnModelCreating(modelBuilder);
var entity = modelBuilder.Entity<Person>();
entity.ToTable("persons");
entity.Property(m => m.Id).HasColumnName("person_id");
entity.Property(m => m.Name).HasColumnName("person_name");
}
}
public class Person
{
public int Id { get; set; }
public string Name { get; set; }
}
