一、控件

1、WebBrowser

浏览器控件

1>属性

Url：导航的网址（在属性栏输入时会自动补全http://）

2、ComboBox

下拉框控件：建议以cbo…格式命名

1>属性

Items：下拉框中的显示内容（可在属性栏中的编辑项、Items以及点击控件上的小三角进行输入）
DropDownStyle：控制下拉框的外观格式

2>事件

SelectedIndexChanged：当前下拉框中的值被选中的时候发生事件

3、ListBox

集合：类似于音乐播放的菜单栏，属性与事件与ComboBox类似

1>属性

Items：下拉框中的显示内容（可在属性栏中的编辑项、Items以及点击控件上的小三角进行输入）

2>事件

DoubleClick：双击时触发事件

4、Panel

容器：与GroupBox类似

5、DataGridView

用于显示表格数据
更改中文表名并绑定相关数据列的操作

二、对话框

OpenFileDialog：打开文件对话框
SaveFileDialog：保存文件对话框
FontDialog：字体对话框
ColorDialog：颜色对话框
