示例

以下示例调用 Win32_Process：：Create 方法以启动 Notepad.exe 的新进程。

using System;
using System.Management;

// This sample demonstrates invoking
// a WMI method using an array of arguments.
public class InvokeMethod
{
    public static void Main()
    {

        // Get the object on which the
        // method will be invoked
        ManagementClass processClass =
            new ManagementClass("Win32_Process");

        // Create an array containing all
        // arguments for the method
        object[] methodArgs =
            {"notepad.exe", null, null, 0};

        //Execute the method
        object result =
            processClass.InvokeMethod(
            "Create", methodArgs);

        //Display results
        Console.WriteLine(
            "Creation of process returned: " + result);
        Console.WriteLine("Process id: " + methodArgs[3]);
    }
}

' using an array of arguments.

    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("Win32_Process")

        ' Create an array containing all arguments

        ' Display results
        Console.WriteLine( _
            "Creation of process returned: {0}", result)
        Console.WriteLine( _
            "Process id: {0}", methodArgs(3))
        Return 0
    End Function
