VB.NET中得到计算机硬件信息

    本文汇集了在.net中得到计算机硬件信息的一些功能。

    得到显示器分辨率

    Dim X As Short = System.<a href="http://dev.21tx.com/os/windows/" target="_blank">Windows</a>.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.GetFold<a href="http://dev.21tx.com/corp/solution/erp/" target="_blank">ERP</a>ath(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
Module mciAPIModule
  Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" _
  (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, _
  ByVal uReturnLength As Integer, ByVal hwndCallback As Integer) As Integer
End Module

'打开CD-ROM
Dim lRet As Long
lRet = mciSendString("set cdAudio door open", 0&, 0, 0)

'关闭CD-ROM
Dim lRet As Long
lRet = mciSendString("set cdAudio door Closed", 0&, 0, 0)
'更多请参见
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/mmcmdstr_8eyc.asp

    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
    Dim opSearch As New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
    Dim opInfo As ManagementObject
    For Each opInfo In opSearch.Get()
  ListBox1.Items.Add("Name: " & opInfo("name").ToString())
  ListBox1.Items.Add("Version: " & opInfo("version").ToString())
  ListBox1.Items.Add("Manufacturer: " & opInfo("manufacturer").ToString())
  ListBox1.Items.Add("Computer name: " & opInfo("csname").ToString())
  ListBox1.Items.Add("Windows Directory: " & opInfo("windowsdirectory").ToString())
Next

    列出计算机安装的全部字体，并添加到ListBox
    '新建Form并添加ListBox和Button
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim fntCollection As InstalledFontCollection = New InstalledFontCollection()
Dim fntFamily() As FontFamily
fntFamily = fntCollection.Families
ListBox1.Items.Clear()
Dim i As Integer = 0
For i = 0 To fntFamily.Length - 1
  ListBox1.Items.Add(fntFamily(i).Name)
Next
End Sub

    使用Win32_Processor列出处理器的信息
