Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?

1. I'm test ModbusTcpMasterReadInputs example.

What is the expected output? What do you see instead?

Console was output right results. But when program closed program fallen at
function TcpStreamAdapter.EndWrite with message 
Cannot access a disposed object.
Object name: 'System.Net.Sockets.NetworkStream'.

If I'm run debug mode, program execute without problem.

What version of the product are you using? On what operating system?
I'm used last version 1.3.0.2. WinXP.

Please provide any additional information below.

After read sometimes,this exception  will throw. cann't catch it ,but if do 
nothing 
with the exception interface,read will be normal. if close the exception 
interface,program will exit.
