DDS C++ - Data Distribution Service

I began to work with C# and I'm trying to test the code that follows for an dds app. I took it from: http://www.laas.fr/files/SLides-A_Corsaro.pdf

using System;
/**********************************************************
 * Definition for the TempSensorType
 **********************************************************/
enum TemperatureScale{
    CELSIUS,
    KELVIN,
    FAHRENHEIT
};
struct TempSensorType{
    short id;
    float temp;
    float hum;
    TemperatureScale scale;
};
#pragma keylist TempSensor id

/**********************************************************
 * Main
 **********************************************************/
static public void Main(string[] args){

    dds::Topic<TempSensorType> tsTopic(TempSensorTopic);
    dds::DataWriter<TempSensorType> dw(tsTopic);
    dds::DataReader<TempSensorType> dr(tsTopic);
    dds::SampleInfoSeq info;

    TempSensorSeq data;
    TempSensorType ts;
    ts = new TempSensorType { 1, 25.0F, 65.0F, CELSIUS };
    dw.write(ts);
    ts = new TempSensorType { 2, 26.0F, 70.0F, CELSIUS };
    dw.write(ts);
    ts = new TempSensorType { 3, 27.0F, 75.0F, CELSIUS };
    dw.write(ts);
    sleep(10);
    while (true){
        dr.read(data, info);
        for (int i = 0; i < data.length(); ++i)
            std::cout << data[i] << std::endl;
        sleep(1);
    }
    Console.WriteLine("Bonjour");
}

I start to understand the purpose of each piece of code. But I'm having doubts about the 4 first lines in the main, thoses that start with "dds::" and I think they are wrong - I'm getting "Identifier expected". If you could help it would be gratefull.

In my opinion it's not valid DDS code. It seems that you're missing the IDL definition (that should explain the #pragma) and the code.

You must at first create topics in a .idl file, then build id in order to create classes that you use in your program, and then use program libraries, and everything is missing.

Start to download a DDS implementation, like OpenDDS or Fast-RTPS. In addition to this you can check the OpenDDS section in this site from a working OpenDDS example from scratch.
