我目前正在一個項目上工作，因爲項目建立了許多代碼行，所以我試圖採取微不足道的方法，並開始使用一些更聰明的方法來使代碼可重複使用的。 所以比如我需要連接到SQL Server：性能和代碼resue之間的平衡
（它可以是任何其他的任務，我正在學習，而我的代碼我所知availble的所有的.NET內置專用類）
真的所有我需要的是： SqlCommand，SqlDataReader（& SqlConnection）及相應的容器對象與數據庫 所以我的測試中返回 通常我使用List<dictionary<string, object>>數據到現在爲止它是很小的，我應該想到。 但是，然後我說啊這是一個很好的方式來連接到SQL並獲取一些rowsets 然後我認爲這是不夠的，因爲還有一些其他種類的返回的數據，所以讓我們做一些替代方案來覆蓋更多的選項，實際上讓我們介紹所有可用的場景，然後我想出了一個包含所有可用數據格式，單記錄多行數據集等的「模型」類。 但這並不是全部還有兩個主要選項可從.NET 從sql server讀取，如SqlDataReader和SqlDataAdapter。所以我會覆蓋這些選項，但是等等，還有我可以使用的魔術詞，比如存儲過程和純文本命令，所以讓我們創建一個類，它將存儲一些破壞來定義存儲過程，然後存儲過程參數，讓做一個簡單的方法來調用存儲過程作爲一個對象，所以後來1行的電話，我們有一個存儲過程的對象......
現在如果我將停止在這裏原因這又是唯一的從那個兔子洞開始，還有很多...甚至不是最好的例子，因爲創建的對象有一個很好的理由來存在，除非你想更有效地編碼它，否則你不會創建那些額外的類和對象 這種行爲和更多的任務，以「每日」爲基礎，我開始看到有一個該模式導致一個巨大的.Cs文件，其中包含大約10個命名空間，每個命名空間都有數十個類和函數。 問題是你如何決定什麼時候使用最少的代碼，什麼時候讓它去，不關心很多原因，嘿，工作站是說.. 8核心I7機器不會有太大的區別，所以我們只需要擔心編碼的簡便性。
你在哪裏放紅線？
編輯下面的代碼是不是一個代碼審查的目的，它只是顯示的應用和性能的影響很可能導致規模。**
這只是的核心數據對象工廠，這是約三分之一的類其中一些在其他任務中的少數幾個。
