示例1: EnumerateInstancesAsync
//引入命名空间
using System;
using System.Management;
// This example demonstrates how
// to perform an asynchronous instance enumeration.
public class EnumerateInstancesAsync
{
public EnumerateInstancesAsync()
{
// Enumerate asynchronously using Object Searcher
// ===============================================
// Instantiate an object searcher with the query
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(new
SelectQuery("Win32_Service"));
// Create a results watcher object,
// and handler for results and completion
ManagementOperationObserver results = new
ManagementOperationObserver();
// Attach handler to events for results and completion
results.ObjectReady += new
ObjectReadyEventHandler(this.NewObject);
results.Completed += new
CompletedEventHandler(this.Done);
// Call the asynchronous overload of Get()
// to start the enumeration
searcher.Get(results);
// Do something else while results
// arrive asynchronously
while (!this.Completed)
{
System.Threading.Thread.Sleep (1000);
}
this.Reset();
