int iCode = Marshal.GetLastWin32Error();
if (infHandle.ToInt64() != INVALID_HANDLE_VALUE)
{
     Console.WriteLine("INF file was opened successfully.");
     INFCONTEXT Context = new INFCONTEXT();
     if (SetupFindFirstLine(infHandle, "Manufacturer", null, ref Context) == true)
     {
        Console.WriteLine("Manufacturers list:");
        string manufacturerName = "";
        manufacturerName = manufacturerName.PadLeft(256, ' ');
        Int32 requiredSize = manufacturerName.Length;
        SetupGetStringField(ref Context, 1, manufacturerName, manufacturerName.Length, out requiredSize);
        manufacturerName = manufacturerName.Substring(0, requiredSize-1);
        Console.WriteLine(manufacturerName);
        while(SetupFindNextLine(ref Context, out Context) == true)
        {
            manufacturerName = manufacturerName.PadLeft(256, ' ');

            Console.WriteLine(manufacturerName);
        }
