四、文件及函數

1、文件說明

　　（1）LQMenu.dbml：創建Linq To SQL類，使其對應數據庫中的core_menu表

　　（2）MyFuncLib.cs：常見的公共函數類，將系統中經常用到的公共的函數放入其中

　　（3）BLMenu.cs：對LQMenu.dbml的數據操作層，用於存放數據增刪改查函數，及其他與數據庫有關的函數

　　（4）FormMenu.cs：窗體的主函數

2、FormMenu_Load函數

　　使用InitDgv函數來初始化DataGridView，當需要修改的時候可以直接在代碼中進行修改。該函數還調用了MyFuncLib.InitDgv，以及後續的兩個函數InitDgvColumns以及IsNumber。

　　（1）FormMenu.InitDgv()
