四、文件及函数
1、文件说明
（1）LQMenu.dbml：创建Linq To SQL类，使其对应数据库中的core_menu表
（2）MyFuncLib.cs：常见的公共函数类，将系统中经常用到的公共的函数放入其中
（3）BLMenu.cs：对LQMenu.dbml的数据操作层，用于存放数据增删改查函数，及其他与数据库有关的函数
（4）FormMenu.cs：窗体的主函数
2、FormMenu_Load函数
使用InitDgv函数来初始化DataGridView，当需要修改的时候可以直接在代码中进行修改。该函数还调用了MyFuncLib.InitDgv，以及后续的两个函数InitDgvColumns以及IsNumber。
（1）FormMenu.InitDgv()
/// <summary> 用代码的方式构造dataGridView，便于修改里面的内容 /// /// </summary> private void InitDGV() { StringBuilder sb = new StringBuilder(); sb.Append("Type=text,Width=100,Visible=true,ReadOnly=false,Frozen=true,Format=,NullValue=,"); sb.Append("Order=false,Alignment=left,MaxInputLength=30,Name=menuName,HeaderText=菜单名称"); sb.Append(";Type=text,Width=90,Visible=true,ReadOnly=false,Frozen=false,Format=,NullValue=,"); sb.Append("Order=false,Alignment=left,MaxInputLength=30,Name=subMenuName,HeaderText=二级菜单"); sb.Append(";Type=text,Width=100,Visible=true,ReadOnly=true,Frozen=false,Format=,NullValue=,"); sb.Append("Order=false,Alignment=left,MaxInputLength=30,Name=title,HeaderText=菜单文本"); sb.Append(";Type=checkbox,Width=70,Visible=true,ReadOnly=false,Frozen=false,Format=,NullValue=0,"); sb.Append("Order=false,Alignment=left,MaxInputLength=30,Name=isForm,HeaderText=是否窗体"); sb.Append(";Type=text,Width=100,Visible=true,ReadOnly=false,Frozen=false,Format=,NullValue=,"); sb.Append("Order=false,Alignment=left,MaxInputLength=100,Name=methodNames,HeaderText=方法列表"); sb.Append(";Type=text,Width=100,Visible=true,ReadOnly=true,Frozen=false,Format=,NullValue=,"); sb.Append("Order=false,Alignment=left,MaxInputLength=30,Name=fullName,HeaderText=完整名称"); sb.Append(";Type=checkbox,Width=70,Visible=true,ReadOnly=true,Frozen=false,Format=,NullValue=0,"); sb.Append("Order=false,Alignment=left,MaxInputLength=30,Name=hasChildren,HeaderText=包含下级"); sb.Append(";Type=checkbox,Width=70,Visible=true,ReadOnly=true,Frozen=false,Format=,NullValue=1,"); sb.Append("Order=false,Alignment=left,MaxInputLength=30,Name=isSys,HeaderText=系统菜单"); sb.Append(";Type=checkbox,Width=30,Visible=false,ReadOnly=false,Frozen=false,Format=,NullValue=,"); sb.Append("Order=false,Alignment=center,MaxInputLength=,Name=parentId,HeaderText=parentId"); sb.Append(";Type=text,Width=100,Visible=false,ReadOnly=false,Frozen=false,Format=,NullValue=0,"); sb.Append("Order=false,Alignment=left,MaxInputLength=,Name=ID_,HeaderText=ID_"); dataGridViewMenu.AutoGenerateColumns = false; dataGridViewMenu.ColumnHeadersDefaultCellStyle.WrapMode = DataGridViewTriState.False; dataGridViewMenu.RowHeadersWidth = 41; dataGridViewMenu.Columns.Clear(); dataGridViewMenu.SelectionMode = DataGridViewSelectionMode.FullRowSelect; MyFuncLib.InitDgv(dataGridViewMenu, sb.ToString()); }
