hi,

am receiving excel sheet data from serialport, when i was received , it's displaying complete rows.

receiving data is in following format:

$ POST,T121,c123,raj,2000,200,12/11/2013,1800 # $ POST,T122,c122,thilak,3000,300,12/10/2013,2700 # $ POST,T123,c123,nagendra,2000,2000,11/09/2013,0 #

but i need to read row by row .$ -->start of row #-->end of row

After reading data i need to place in corresponding column of another excel sheet.here , is the delimeter

here is the code:

C#

 private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
        {
Thread.Sleep(50);
                        byte[] buffer=new byte[serialPort1.BytesToRead];
                        serialPort1.Read(buffer,0,buffer.Length);
                        string s = System.Text.ASCIIEncoding.ASCII.GetString(buffer);
                        MessageBox.Show(s);
              }

Solution 1

So, either use string.Split and then string.Trim each line, or use a regex to split and trim at the same time.

Probably, I'd go with a regex, then use Linq to tidy up afterwards:

C#

string inp = "$ POST,T121,c123,raj,2000,200,12/11/2013,1800 # $ POST,T122,c122,thilak,3000,300,12/10/2013,2700 # $ POST,T123,c123,nagendra,2000,2000,11/09/2013,0 # ";
string[] lines = Regex.Split(inp, "[$#]").Where(s => !string.IsNullOrWhiteSpace(s)).Select(s => s.Trim()).ToArray();
