Question on WMI and System.Management class

[Gancy]

Hello,

The code below enumerates all products installed on any given machine.
Through System.Management i can also find WMI methods that could be
exected. But i have not worked on WMI and System.Management before, i
need to know how to execute the those mehtods
ConnectionOptions options = new ConnectionOptions();
options.Authority = "NTLMDOMAIN:DOMAIN_X";
options.Username = "xyz";
options.Password = "xyz123";
string Machine = "abc";

ManagementScope scope = new ManagementScope("\\\\" + Machine +
"\\root\\CIMv2", options);
scope.Connect();

//Query system for all Installed products information
ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_Product");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope,
query);

// Call Get() to retrieve the collection of objects and loop through it
textBoxPrinters.Text = textBoxPrinters.Text + "*** Applications on '" +
Machine + " are\r\n";
foreach (ManagementBaseObject oPrinter in searcher.Get())
{
textBoxPrinters.Text = textBoxPrinters.Text +
oPrinter["Name"].ToString() + "\r\n";
}

//Get the object on which the method will be invoked
ManagementClass processClass = new ManagementClass("Win32_Product");

textBoxPrinters.Text = textBoxPrinters.Text + "\r\n\r\n**** Methods
****\r\n";
foreach(MethodData oPrinterMethods in processClass.Methods)
{

Diagnostics.WriteLine(processClass.Methods[oPrinterMethods.Name.ToString()
}
When you execute this code it will write following line to console
output...

*** Applications on 'abc' are

Microsoft Windows Services for UNIX
Program Files
Microsoft FrontPage Client - English
Camera Window DS
Microsoft SQL Server VSS Writer
Microsoft AntiSpyware

......

**** Methods *****
