安装打印机驱动程序的代码适用于 Windows 7，但不适用于 Windows 8

Question

我尝试使用此 C# 代码将打印机和打印机驱动程序添加到 Windows。它适用于 Windows 7，但不适用于 Windows 8。代码调用 moPrinter.Put() 时发生异常（一般故障）。谁能说出为什么在运行 Windows 8 时会遇到此错误，而为什么不是 Windows 7？

    public static bool AddCanonPrinter()
    {
        bool flag = true;
        try
        {
            String portNumber = "9100";
            String printerIP = "157.198.192.42";
            String portName = "IP_" + printerIP;
            ConnectionOptions options = new ConnectionOptions();
            options.EnablePrivileges = true;
            ManagementScope mscope = new ManagementScope(ManagementPath.DefaultPath, options);
            mscope.Connect();

            ManagementPath mpPort = new ManagementPath("Win32_TCPIPPrinterPort");
            ManagementClass mcPort = new ManagementClass(mscope, mpPort, new ObjectGetOptions());
            ManagementObject moPort = mcPort.CreateInstance();
            moPort.Properties["Name"].Value = portName;
            moPort.Properties["HostAddress"].Value = printerIP;
            moPort.Properties["PortNumber"].Value = portNumber;
            moPort.Properties["Protocol"].Value = 1;
            moPort.Put();

            ManagementPath mpPrinter = new System.Management.ManagementPath("Win32_Printer");
            ManagementClass mcPrinter = new ManagementClass(mscope, mpPrinter, new ObjectGetOptions());
            ManagementObject moPrinter = mcPrinter.CreateInstance();
            moPrinter.Properties["Name"].Value = "Canon";
            moPrinter.Properties["DeviceID"].Value = "Canon";
            moPrinter.Properties["DriverName"].Value = "Canon iR C2880/C3380";
            moPrinter.Properties["PortName"].Value = portName;
            moPrinter.Properties["Network"].Value = true;
            moPrinter.Properties["Shared"].Value = false;
            moPrinter.Put();
        }
        catch
        {
            int msgCode = Marshal.GetLastWin32Error();
            string msg = GetSystemMessage(msgCode);
            flag = false;

        }

        return flag;
    }

其实在我调查问题后，我发现windows 8中的打印机驱动程序名称不同。所以相同的代码可以在windows 8中使用并成功运行。
