Beispiel
Im folgenden Beispiel wird die Win32_Process::Create-Methode aufgerufen, um einen neuen Prozess von Calc.exe zu starten. Die Methode wird mit der InvokeMethodOptions-Klasse aufgerufen.
Imports System
Imports System.Management
' This sample demonstrates invoking
' a WMI method using parameter objects
Class InvokeMethod
Public Overloads Shared Function _
Main(ByVal args() As String) As Integer
' Get the object on which the
' method will be invoked
Dim processClass As _
New ManagementClass("root\CIMV2", _
"Win32_Process", _
Nothing)
' Get an input parameters object for this method
Dim inParams As ManagementBaseObject = _
processClass.GetMethodParameters("Create")
' Fill in input parameter values
inParams("CommandLine") = "calc.exe"
' Method Options
Dim methodOptions As New InvokeMethodOptions( _
Nothing, System.TimeSpan.MaxValue)
' Execute the method
Dim outParams As ManagementBaseObject = _
processClass.InvokeMethod( _
"Create", inParams, methodOptions)
' Display results
