Serialport List Read problem and NullReferenceException?
- by Plumbum7
Hello everybody,
Using Microsoft VC# 2008 Express
(little fact about me : non experience in c#, programskills further very beginnerlevel.
This peace op program is to communicate with Zigbee switching walloutlets (switching, status info).
and is downloaded from http://plugwiselib.codeplex.com/SourceControl/list/changesets
The problem:
NullRefferenceException was UnHandled
private void port_DataReceived(object sender, SerialDataReceivedEventArgs e)
{// Event for receiving data
string txt = port.ReadExisting();
Console.WriteLine(txt);
List<PlugwiseMessage> msg = reader.Read (Regex.Split (txt, "\r\n" ));
//Console.WriteLine( msg );
DataReceived(sender, new System.EventArgs(), msg);
VC# Marks the last line and says msg is empty. so i looked further.
Msg come's from txt text is filled with
"000002D200C133E1\r\nPutFifoUnicast 40 : Handle 722 :"<
so it goes wrong in or reader.Read or in the List
so i looked further:
public List<PlugwiseMessage> Read(string[] serialData)
{
Console.WriteLine(serialData);
List<PlugwiseMessage> output = new List<PlugwiseMessage>();
Console.WriteLine(output);
Both (serialData) as (output); are empty.
So can i assume that the problem is in:
Read(string[] serialData)
But now the questions,
Is Read(string[] serialData) something which is a Windows.Refence or is is from a Method ? and IF this is so is this then reader.READ (how can i find this)? (answered my own question proberly)(method reader)(private PlugwiseReader reader)
So why isn't is working trough the serialData ? or is it the List<PlugwiseMessage> part, but i have no idea how it is filled can sombody help me ?
