adding printer driver using system.management

[gv]

I have been successful at adding a printer driver and printer using wmi
script, but converting it to c# has been a challenge.
Can anyone help me with the conversion? Below is the script, and below that
is the code I've tried already, along with the error that I'm getting.

The following works great
strComputer = "."
Set objWMIService = GetObject("winmgmts:" & strComputer & "\root\cimv2")
objWMIService.Security_.Privileges.AddAsString "SeLoadDriverPrivilege"

Set objDriver = objWMIService.Get("Win32_PrinterDriver")

objDriver.Name = "HP LaserJet 4200 PS"
objDriver.SupportedPlatform = "x86"
objDriver.Version = "Windows 2000, Windows XP and Windows Server 2003"
objDriver.FilePath = "C:\\hp4200ps.inf"
objDriver.InfName = "hp4200ps.inf"

intResult = objDriver.AddPrinterDriver(objDriver)
WScript.Echo intResult

The following gives me an error stating "Not found" on the 3rd line below
(SetPropertyValue) as well as setting a property using the brackets []

ManagementClass mc = new ManagementClass("Win32_PrinterDriver");
ManagementBaseObject inParams =
mc.GetMethodParameters("AddPrinterDriver");

inParams.SetPropertyValue("InfName", "hp4200ps.inf");

// inParams["InfName"] ="hp4200ps.inf";
inParams["DriverName"] = "HP LaserJet 4200 PS";
inParams["SupportedPlatform"] = "x86";
inParams["Version"] = "Windows 2000, Windows XP and Windows Server
2003";
inParams["FilePath"] = @"C:\hp4200ps.inf";

ManagementBaseObject outParams = mc.InvokeMethod("AddPrinterDriver",
inParams, null);

uint retVal = (uint)outParams["ReturnValue"];

Console.WriteLine("Win32_PrinterDriver::Create returned {0}",
outParams["ReturnValue"]);

Any help will be greatly appreciated.
Thanks

The reason of the Not Found error is because AddPrinterDriver method takes
only one input parameter. The parameter name is DriverInfo, and it takes an
instance of Win32_PrinterDriver according to PSDK, although the method
appears to work fine if you use the Win32_PrinterDriver class to supply
input data. I prefer to spawn a new instance of Win32_PrinterDriver in this
case. e.g.

ManagementClass mc = new ManagementClass("Win32_PrinterDriver");
ManagementBaseObject inParams = mc.GetMethodParameters("AddPrinterDriver");

ManagementObject driver = new
ManagementClass("Win32_PrinterDriver").CreateInstance();
driver["Name"] = "HP LaserJet 4200 PS";
...
inParams["DriverInfo"] = driver;

ManagementBaseObject outParams = mc.InvokeMethod("AddPrinterDriver",
inParams, null);

Fantastic, much thanks. Although I'm getting a return value of 87 (and msdn
says the only return values for addprinterdriver are 0, 5, 1787), its still
a lot farther than I was earlier today.
Thanks again

According to Error Lookup, 87 means the parameter is incorrect. Please
verify the parameters used.

Inching slowly ahead. The reason for the 87, was the infName property
needed the path as well as the file name. See below. But just like the
script returned an error 5, for not having the privileges, so is the code
below, so the script needed the this line,
objWMIService.Security_.Privileges.AddAsString "SeLoadDriverPrivilege
So do I need to add the Security_ property, then add the Privileges property
to that previous property, then Invoke the AddAsString method with the value
of "SeLoadDriverPrivilege"?
If so, I can't figure out the syntax for that, and I am unable to find any
examples on MSDN, or any newsgroups.
Any thoughts?

Thus far, the following has correct parameters (and returns error 5 for not
having the correct privileges).

ManagementClass mc = new ManagementClass("Win32_PrinterDriver");

ManagementObject driver = new
ManagementClass("Win32_PrinterDriver").CreateInstance();
ManagementBaseObject inParams =
mc.GetMethodParameters("AddPrinterDriver");

driver["Name"] = "HP LaserJet 4200 PS";

driver["SupportedPlatform"] = "Windows NT x86";
driver["Version"] = "3";
driver["FilePath"] = @"C:\Driver";
driver["InfName"] = @"C:\Driver\hp4200ps.inf";
driver["Description"] = "HP LaserJet 4200 PS";

inParams["DriverInfo"] = driver;
ManagementBaseObject outParams = mc.InvokeMethod("AddPrinterDriver",
inParams, null);

uint retVal = (uint)outParams["ReturnValue"];

Apparently setting privileges is different in code than in script. I had to
set up a ConnectionOptions object, set its EnablePrivileges property, and
tie a ManagementScope object with a ManagementClass object. The following
worked. Hopefully I can save someone else from spinning their wheels for
some time.
Thanks Andy for your time.

ConnectionOptions options = new ConnectionOptions();
options.EnablePrivileges = true;
ManagementScope ms = new ManagementScope("\\root\\CIMV2", options);
ms.Connect();

ManagementClass mc = new ManagementClass("Win32_PrinterDriver");

mc.Scope = ms;

ManagementObject driver = new
ManagementClass("Win32_PrinterDriver").CreateInstance();
ManagementBaseObject inParams =
mc.GetMethodParameters("AddPrinterDriver");

driver["Name"] = "HP LaserJet 4200 PS";
driver["SupportedPlatform"] = "Windows NT x86";
driver["Version"] = "3";
driver["FilePath"] = @"C:\Driver";
driver["InfName"] = @"C:\Driver\hp4200ps.inf";
driver["Description"] = "HP LaserJet 4200 PS";

inParams["DriverInfo"] = driver;

ManagementBaseObject outParams = mc.InvokeMethod("AddPrinterDriver",
inParams, null);

uint retVal = (uint)outParams["ReturnValue"];
