C# Database.SetInitializer 幾種常見用法

            //數據庫不存在時重新創建數據庫
            Database.SetInitializer(new CreateDatabaseIfNotExists<SqlDbContext>());
            //每次啟動應用程序時創建數據庫
            Database.SetInitializer(new DropCreateDatabaseAlways<SqlDbContext>());
            //模型更改時重新創建數據庫
            Database.SetInitializer(new DropCreateDatabaseIfModelChanges<SqlDbContext>());
            //從不創建數據庫
            Database.SetInitializer<SqlDbContext>(null);
