You can use the SerialPort Class in .NET to accomplish this. Use Read(...) and Write(...) methods to accomplish your task.

Firstly, you add serialPort1 tools in your form and after using

if (!sensport.IsOpen)
            {
                foreach (string port in SerialPort.GetPortNames())
                {
                    sensport.PortName = port;
                    sensport.BaudRate = 9600;
                    MessageBox.Show(port + " is open");
                }
                label1.Text = "";
                try
                {
                    sensport.Open();
                }
                catch (Exception)
                {

                    MessageBox.Show("Please control your connection");
                }               
            }

that codes to open your port.

After that you need Write() and Read() method in serialPort1.
