ManagementObject.Get Method (ManagementOperationObserver)

Binds to the management object asynchronously.

Namespace:  System.Management
Assembly:  System.Management (in System.Management.dll)

public void Get(
	ManagementOperationObserver watcher
)

Parameters

watcher
Type: System.Management.ManagementOperationObserver

The object to receive the results of the operation as events.

The method will issue the request to get the object and then will immediately return. The results of the operation will then be delivered through events being fired on the watcher object provided.

.NET Framework Security

Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.

The following example calls the Get method to asynchronously get an instance of the ManagementObject class.

using System;
using System.Management;

public class AsyncGetExample
{
    public AsyncGetExample() 
    {
        ManagementObject o = 
            new ManagementObject(
            "Win32_Process.Name='notepad.exe'");

        // Set up handlers for asynchronous get
        ManagementOperationObserver ob = 
            new ManagementOperationObserver();
        ob.Completed += new
            CompletedEventHandler(this.Done);

        // Get the object asynchronously
        o.Get(ob);

        // Wait until operation is completed 
        while (!this.Completed)
            System.Threading.Thread.Sleep (1000);

        // Here you can use the object

    }

    private bool completed = false;

    private void Done(object sender,
        CompletedEventArgs e)
    {
        Console.WriteLine("async Get completed !");
        completed = true;
    }

    private bool Completed
    { 
        get 
        {
            return completed;
        }
    }

    public static void Main()
    {
        AsyncGetExample example =
            new AsyncGetExample();

    }
}
