Question on WMI and System.Manageme nt class

[Gancy]

Hello,

The code below enumerates all products installed on any given machine.
Through System.Manageme nt i can also find WMI methods that could be
exected. But i have not worked on WMI and System.Manageme nt before, i
need to know how to execute the those mehtods
ConnectionOptio ns options = new ConnectionOptio ns();
options.Authori ty = "NTLMDOMAIN:DOM AIN_X";
options.Usernam e = "xyz";
options.Passwor d = "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("SE LECT * FROM Win32_Product") ;
ManagementObjec tSearcher searcher = new ManagementObjec tSearcher(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 (ManagementBase Object 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(MethodD ata oPrinterMethods in processClass.Me thods)
{

Diagnostics.Wri teLine(processC lass.Methods[oPrinterMethods .Name.ToString( )
}
When you execute this code it will write following line to console
output...

*** Applications on 'abc' are
