System::Management::ManagementObjectCollection ^ GetInstances();
public System.Management.ManagementObjectCollection GetInstances ();
member this.GetInstances : unit -> System.Management.ManagementObjectCollection
Public Function GetInstances () As ManagementObjectCollection
Returns
A collection of the ManagementObject objects representing the instances of the class.
Examples
The following example shows how to initialize a ManagementClass variable with a ManagementClass constructor and then get all the instances of a WMI class.
using System;
using System.Management;
public class Sample
{
public static void Main()
{
ManagementClass c = new ManagementClass("Win32_Process");
foreach (ManagementObject o in c.GetInstances())
Console.WriteLine(
"Next instance of Win32_Process : {0}", o["Name"]);
}
}
