[Mono-dev] HOW WOULD BE THE CONVERSION OF THIS CODE IN MONO USING PINVOKE? I have problems in the structure.

[Justin Cherniak]

Jose,

You posted to mono-list a few days ago and received a few responses.  What
was the problem?  Are you getting some error?

If I were to translate it, I would do the following:

    struct Request
    {
        [MarshalAs(UnmanagedType.LPStr)]
        public string CategoryID;

        [MarshalAs(UnmanagedType.LPStr)]
        public string Product_Code;

        [MarshalAs(UnmanagedType.LPStr)]
        public string Build_Code;

        [MarshalAs(UnmanagedType.LPStr)]
        public string Manufacturer_id;

        public uint Serial_Number;

        [MarshalAs(UnmanagedType.LPStr)]
        public string Software_Version;
    };

    public class Test
    {
        [DllImport("lib.dll")]
        public static extern int Manufacture(IntPtr handle, out Request
req);

        [DllImport("lib.dll")]
        public IntPtr GetHandle(); /* Unmanaged function that returns the
needed
                                              * handle since there is no way
to import
                                              * global variables */

        public static void Main(string[] args)
        {
            Request ID_Device;
            int Resultado;

            IntPtr handle = GetHandle();

            Resultado = Manufacture(piHandle_coin, ref ID_Device);
//*****************problems in &ID_Device STRUCTURE UNMANAGED TO MANAGED AS
PARAMETER
            Console.WriteLine("Id Categoria : {0}\n", ID_Device.CategoryID);
            Console.WriteLine("Id Product: {0}\n", ID_Device.Product_Code);
            Console.WriteLine("Id Build: {0}\n", ID_Device.Build_Code);
            Console.WriteLine("Manufacturer: {0}\n",
ID_Device.Manufacturer_id);
            Console.WriteLine("Serial Number: {0}\n",
ID_Device.Serial_Number);
            Console.WriteLine("Software Revision: {0}\n\n",
ID_Device.Software_Version);
        }
    }

Enjoy,
Justin
