How can i receive data from Mega2560 on PC with Visual C#

Question

How can i receive the data from my Arduino Mega 2560 with Visual C# on my PC.

I send a short databyte (2 bytes) and a timestamp (4 bytes) over USB to PC

//initialization
const int RX = 0;
const int TX = 1; 
void setup(){
pinMode(RX, INPUT); //readpin for USB
pinMode(TX, OUTPUT); //writepin for USB
... 
Serial.begin(28800); //open interface
}
 //loop()
 Serial.print(incomingByte, BIN); //sending databyte
 sendBinary(currentMillis); //send timestamp
//method for timestamp
void sendBinary(long currnetMillis)
 {
 int temp = currentMillis&0xFFFF; //16 bit of the low-byte
 sendBinary(temp);
 temp = currentMillis >> 16; //16 bit of the high-byte
 sendBinary(temp);
 }

I have surched in the internet for an example but i didn ́t find a good. So i ask here what ist the best way with Visual Studio C# to receive the incoming data? An example code will be nice because i ́m a beginner and didn ́t understand the jargon.

I haven't tried the code below, but it should point you in the right direction.

All you have to do is write a C# program that opens the Serial port that your Arduino is connected to and read and write from there like you would from a file.

1. Open Visual Studio, create a C# command line project.

2. Paste this code inside main()

    System.IO.Ports.SerialPort port = new SerialPort("COM1", 9600);
    try
    {
    while (true)
    {
    int readData = port.ReadByte();
    System.Console.WriteLine("Read {0} from the port", readData);
    }
    }
    catch(Exception) // Press CTRL-C to exit.
    {
    }
    port.Close();
   

3. Compile the code and run it.
