Examples
The following example connects to a remote computer and displays information about the operating system on the remote computer. A ConnectionOptions is created to connect to the remote computer with default connection options.
using System;
using System.Management;
public class RemoteConnect
{
public static void Main()
{
// Build an options object for the remote connection
// if you plan to connect to the remote
// computer with a different user name
// and password than the one you are currently using.
// This example uses the default values.
ConnectionOptions options =
new ConnectionOptions();
// Make a connection to a remote computer.
// Replace the "FullComputerName" section of the
// string "\\\\FullComputerName\\root\\cimv2" with
// the full computer name or IP address of the
// remote computer.
ManagementScope scope =
new ManagementScope(
"\\\\FullComputerName\\root\\cimv2", options);
scope.Connect();
//Query system for Operating System information
ObjectQuery query = new ObjectQuery(
"SELECT * FROM Win32_OperatingSystem");
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(scope,query);
ManagementObjectCollection queryCollection = searcher.Get();
