3、执行代码
public class Destination
{
public int DestinationId { get; set; }
public string Name { get; set; }
public string Country { get; set; }
public string Description { get; set; }
public string Description12345 { get; set; }
public byte[] Photo { get; set; }
public List<Lodging> Lodgings { get; set; }
}
public class Lodging
{
public int LodgingId { get; set; }
public string Name { get; set; }
public string Owner { get; set; }
public bool IsResort { get; set; }
public bool IsResort1 { get; set; }
public bool IsResort2 { get; set; }
public Destination Destination { get; set; }
}
public class BreakAwayContext : DbContext
{
public BreakAwayContext()
: base("MyContext")
{
}
public DbSet<Destination> Destinations { get; set; }
public DbSet<Lodging> Lodgings { get; set; }
}
static void Main(string[] args)
{
var d = DateTime.Now.Date.ToString("yyyyMM");
var destination = new Destination
{
Country = "Indonesia",
Description = "EcoTourism at its best in exquisite Bali",
Name = "Bali"
};
using (var context = new BreakAwayContext())
{
context.Destinations.Add(destination);
context.SaveChanges();
}
Console.WriteLine("OK");
}
