Get()

Binds WMI class information to the management object.
public:
void Get();
public void Get ();
member this.Get : unit -> unit
Public Sub Get ()
Examples
The following example calls the Get method to get an instance of the ManagementObject class.
using System;
using System.Management;
class Sample
{
public static int Main(string[] args)
{
ManagementObject o =
new ManagementObject("MyClass.Name='abc'");
//this causes an implicit Get().
string s = o["Name"].ToString();
Console.WriteLine(s);
//or :
ManagementObject mObj =
new ManagementObject("MyClass.Name= 'abc'");
mObj.Get(); //explicitly
// Now it is faster because the object
// has already been retrieved.
string property = mObj["Name"].ToString();
Console.WriteLine(property);
return 0;
}
}
Imports System.Management
Class Sample_ManagementClass
Public Overloads Shared Function Main( _
ByVal args() As String) As Integer
Dim o As New ManagementObject( _
"MyClass.Name=""abc""")
'this causes an implicit Get().
Dim s As String = o("SomeProperty")
Console.WriteLine(s)
'or :
Dim mObj As New ManagementObject("MyClass.Name= ""abc""")
mObj.Get() 'explicitly
' Now it is faster because the object
' has already been retrieved.
Dim p As String = mObj("SomeProperty")
Console.WriteLine(p)
Return 0
End Function
End Class
Remarks
The method is implicitly invoked at the first attempt to get or set information to the WMI object. It can also be explicitly invoked at the user's discretion, to better control the timing and manner of retrieval.

Binds to the management object asynchronously.
public:
void Get(System::Management::ManagementOperationObserver ^ watcher);
public void Get (System.Management.ManagementOperationObserver watcher);
member this.Get : System.Management.ManagementOperationObserver -> unit
Public Sub Get (watcher As ManagementOperationObserver)
Parameters
- watcher
- ManagementOperationObserver
The object to receive the results of the operation as events.
Examples
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();
}
}
Imports System.Management
Class AsyncGetExample
Public Sub New()
Dim o As New ManagementObject( _
"Win32_Process.Name=""notepad.exe""")
'Set up handlers for asynchronous get
Dim ob As New ManagementOperationObserver
AddHandler ob.Completed, AddressOf Me.Done
'Get the object asynchronously
o.Get(ob)
'Wait until operation is completed
While Not Me.Completed
System.Threading.Thread.Sleep(1000)
End While
'Here you can use the object
End Sub
Private _completed As Boolean = False
Private Sub Done(ByVal sender As Object, _
ByVal e As CompletedEventArgs)
Console.WriteLine("async Get completed !")
_completed = True
End Sub
Private ReadOnly Property Completed() As Boolean
Get
Return _completed
End Get
End Property
Public Overloads Shared Function Main( _
ByVal args() As String) As Integer
Dim example As New AsyncGetExample
Return 0
End Function
End Class
Remarks
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.
