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.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
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)
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
Imports System.Management
Public Class Form1
Inherits System.Windows.Forms.Form
#Region " Windows 窗体设计器生成的代码 "
Public Sub New()
MyBase.New()
'该调用是 Windows 窗体设计器所必需的。
InitializeComponent()
