示例1: InvokeMethodAsync
//引入命名空间
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);
}
}
// Property allows accessing the result
// object in the main function
private ManagementBaseObject ReturnObject
{
get
{
return returnObject;
}
}
// Delegate called when the method completes
// and results are available
private void NewObject(object sender,
ObjectReadyEventArgs e)
{
Console.WriteLine("New Object arrived!");
returnObject = e.NewObject;
}
// Used to determine whether the method
// execution has completed
private bool IsComplete
{
get
{
return isComplete;
}
}
private void Completed(object sender,
CompletedEventArgs e)
{
isComplete = true;
Console.WriteLine("Method invoked.");
}
public static void Main()
{
InvokeMethodAsync invokeMethod = new InvokeMethodAsync();
return;
}
