获取硬件信息

得到显示器分辨率
Dim X As Short = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width
Dim Y As Short = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height
MsgBox("您的显示器分辨率是：" & X & " X " & Y)

得到特殊文件夹的路径
'"Desktop"桌面文件夹路径
MsgBox(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory))
'"Favorites"收藏夹路径
MsgBox(Environment.GetFolderPath(Environment.SpecialFolder.Favorites))
'"Application Data"路径
MsgBox(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData))

'通用写法
'Dim SPEC As String = Environment.GetFolderPath(Environment.SpecialFolder.XXXXXXX)
'XXXXXXX是特殊文件夹的名字

得到操作系统版本信息
MsgBox(Environment.OSVersion.ToString)

得到当前登录的用户名
MsgBox(Environment.UserName)

得到当前应用程序的路径
MsgBox(Environment.CurrentDirectory)

打开和关闭CD-ROM
'先新建模块

得到计算机IP和计算机全名
Dim MYIP As System.Net.IPHostEntry = System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName)
MsgBox("您的IP地址：" & (MYIP.AddressList.GetValue(0).ToString))
MsgBox("您的计算机全名：" & (MYIP.HostName.ToString))

使用win32_operatingSystem (wmi Class)得到计算机信息
'添加ListBox在Form1_Load事件里，并引用system.Managment
