You can use Port object from System.IO.Ports  set a port parameters and read data  from  it
to set com parameters use

comport.BaudRate, comport.DataBits ,comport.StopBits ,comport.Parity ,comport.PortName ,comport.ReadTimeout

to open it make use

comport.Open();

to read data from it use

comport.ReadExisting()
