Thanks Craig, after looking at https://stackoverflow.com/a/5974656/968301 it was pretty simple.
创建一个intializer
Create an intializer
public class MyInitializer : DropCreateDatabaseIfModelChanges<MyContext>
{
protected override void Seed(MyContext context)
{
context.Database.ExecuteSqlCommand("DBCC CHECKIDENT ('Account', RESEED, 1000000)");
}
}
然后从Global.asax的Application_Start部分调用.cs
Then call from the Application_Start section of the Global.asax.cs
protected void Application_Start()
{
Database.SetInitializer(new MyInitializer());
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
}
