HDI send a final msg via TcpClient before my class closes?

Question

Hi Guys,

 

Im having trouble sending a final command to a service before my class closes. 

I have a startupclient that starts when my application starts and attempts to send a "QUIT" message from the class destructor as the class is closing.

Unfortunately when calling SendCommand("QUIT") from the class destructor, I get an exception from the SendCommand method.

 

System.ObjectDisposedException was unhandled

HResult=-2146232798

Message=Cannot access a disposed object.

Object name: 'System.Net.Sockets.TcpClient'.

ObjectName=System.Net.Sockets.TcpClient

Source=System

StackTrace:

at System.Net.Sockets.TcpClient.GetStream()

at Skeleton.Classes.clsStartupClient.SendCommand(String Command, String Param)

at Skeleton.Classes.clsStartupClient.SendCommand(String Command)

at Skeleton.Classes.clsStartupClient.Finalize()

InnerException:

on the line below in the SendCommand() method.

StreamWriter wtr = new StreamWriter(Cli.GetStream()); 

 

 

 

How would I be able to send a final SendCommand message before the class closes?

 

Thanks in advance.
