如何用VB检测计算机名称、IP、MAC和内存大小

IT领域,获取计算机名称IP地址MAC地址以及内存大小等关键信息非常重要。将详细介绍如何通过VB代码实现这一目标。

获取计算机名称

计算机名称是操作系统中用于区分不同设备的标识。在VB中,可以通过Environment类中的MachineName属性获取:

Dim computerName As String
computerName = Environment.MachineName

获取IP地址

IP地址是网络中设备的唯一标识,通常为IPv4。可使用System.NetworkInformation中的NetworkInterface类来获取:

Imports System.NetworkInformation
Dim ipAddresses() As IPInterfaceProperties = NetworkInterface.GetAllNetworkInterfaces()
For Each ipProps As IPInterfaceProperties In ipAddresses
    If ipProps.OperationalStatus = OperationalStatus.Up Then
        Dim ipAddr() As IPAddress = ipProps.GetIPProperties().UnicastAddresses
        For Each ip As IPAddress In ipAddr
            If ip.AddressFamily = AddressFamily.InterNetwork Then
                Console.WriteLine("IPv4地址: " & ip.ToString())
                Exit For
            End If
        Next
    End If
Next

获取MAC地址

MAC地址是网络接口的物理地址。通过NetworkInterface.GetAllNetworkInterfaces()方法获取:

Dim macAddress As PhysicalAddress
For Each ni As NetworkInterface In NetworkInterface.GetAllNetworkInterfaces()
    If ni.OperationalStatus = OperationalStatus.Up AndAlso ni.NetworkInterfaceType <> NetworkInterfaceType.Loopback Then
        macAddress = ni.GetPhysicalAddress()
        Console.WriteLine("MAC地址: " & macAddress.ToString())
        Exit For
    End If
Next

获取内存大小

系统的总内存大小可用Microsoft.VisualBasic.Devices.ComputerInfo类的TotalPhysicalMemory属性获得:

Imports Microsoft.VisualBasic.Devices
Dim memorySize As Long
memorySize = ComputerInfo.TotalPhysicalMemory
Console.WriteLine("内存大小: " & memorySize / 1024 & " MB")

以上代码为系统监控、网络管理及故障排查提供了基础信息采集方案,可以根据需求将这些功能整合到程序中,增强自动化管理和数据跟踪能力。
