几个 WMI 的例子（初级） - 2

下面收集了一些例子；

获取本地硬盘的信息：

Imports System

Imports System.Management

Module Module1

    Public Sub Main()

        Dim disk As ManagementObject = New ManagementObject("win32_logicaldisk.deviceid=""c:""")

        disk.Get()

        Console.WriteLine("Logical disk size is " + disk("Size").ToString + " bytes")

    End Sub

End Module

驱动器类型disk(“DriveType”)：

从新启动远程计算机：（需要权限）

Imports System

Imports System.Management

Module Module1

    Public Sub Main()

        Dim co As ConnectionOptions = New ConnectionOptions

        co.Username = "Admin"´登录的用户名称

        co.Password = "12345678"´Password

        Dim ms As System.Management.ManagementScope = New System.Management.ManagementScope("\\192.168.1.2\root\cimv2", co)

        Dim oq As System.Management.ObjectQuery = New System.Management.ObjectQuery("SELECT * FROM Win32_OperatingSystem")

        Dim mos As ManagementObjectSearcher = New ManagementObjectSearcher(ms, oq)

        Dim _query As ManagementObjectCollection = mos.Get()

        Dim mo As ManagementObject

        For Each mo In _query

            Dim tmp() As String = {""}

            mo.InvokeMethod("Reboot", tmp)

            Console.WriteLine(mo.ToString())

        Next

    End Sub

End Module

建立一个进程：

Imports System

Imports System.Management

Module Module1

    Public Sub Main()

        Dim processClass As ManagementClass = New ManagementClass("Win32_Process")

        Dim inParams As ManagementBaseObject = processClass.GetMethodParameters("Create")

        inParams("CommandLine") = "calc.exe"

        Dim outParams As ManagementBaseObject = processClass.InvokeMethod("Create", inParams, Nothing)

        Console.WriteLine("Creation of calculator process returned: " + outParams("returnvalue"))

        Console.WriteLine("进程 ID：" & outParams("processId"))

    End Sub

End Module
