以zip和rar為例說明 strategy pattern
如果把相關的演算法全都寫入同一個物件, 然後利用條件式判斷(if or switch)來判斷所要執行的版本 但這樣有一些缺點 1. 程式碼容易變得龐大複雜, 不容易修改 2. 記憶體效能降低, 因為物件包含全部的演算法 3. 擴充新的演算法或是改良版演算法(modified xxx algorithm)必須動到既有的程式碼

Writing an OCR example Using eVsion .NET Component
點選<加入參考>, 第一次執行加入參考, Visual Studio會執行一段時間(正常), 因為會掃描整個系統相容元件的關係 點選.NET物件 C:\Program Files (x86)\Euresys\eVision\NET Components Visual Studio 2010->偵錯->例外狀況 原廠範例程式,預設值LoaderLock是打勾, 但這個會造成執行階段錯誤!
