//晓得怎么搞了
if (!context.Feedbacks.Any())
{
context.Feedbacks.AddRange(
new Feedback { Name = "张三", Email = "zhangsan@hotmail.com", CreateDateUTC = DateTime.Now, Message = "味道香" },
new Feedback { Name = "李四", Email = "lisi@hotmail.com", CreateDateUTC = DateTime.Now, Message = "味道很香" },
new Feedback { Name = "王五", Email = "wangwu@hotmail.com", CreateDateUTC = DateTime.Now, Message = "味道真香" },
new Feedback { Name = "赵六", Email = "zhaoliu@hotmail.com", CreateDateUTC = DateTime.Now, Message = "味道贼香" }
);
context.SaveChanges();//保存数据库;
}
