Ejemplos

En el ejemplo siguiente se llama a un método de forma asincrónica.The following example calls a method asynchronously. Se llama al método Win32_Process. Create para crear un nuevo proceso para Calc.exe.The Win32_Process.Create method is called to create a new process for Calc.exe.

using System;
using System.Management;

public class InvokeMethodAsync
{
    private bool isComplete = false;
    private ManagementBaseObject returnObject;

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

        // Create a results and completion handler
        ManagementOperationObserver handler =
            new ManagementOperationObserver();
        handler.Completed +=
            new CompletedEventHandler(this.Completed);

        // Invoke method asynchronously
        ManagementBaseObject inParams =
            processClass.GetMethodParameters("Create");
        inParams["CommandLine"] = "calc.exe";
        processClass.InvokeMethod(
            handler, "Create", inParams, null);

        // Do something while method is executing
        while(!this.IsComplete)
        {
            System.Threading.Thread.Sleep(1000);

    // object in the main function

    // and results are available

    {
        Console.WriteLine("New Object arrived!");
        returnObject = e.NewObject;
