Issue: System.Net.Sockets.SocketException: A blocking operation was interrupted by a call to WSACancelBlockingCall.

Background

Use the threadstart delegate thread to listen for socket traffic and call Savetrainresult commit after the communication is complete

now the question

the socket communication succeeds and the data parsing succeeds, but the savetrainresult method Times exception information is called :

System.Net.Sockets.SocketException: A blocking operation was interrupted by a call to WSACancelBlockingCall .

At System.Net.Sockets.Socket.Accept () [0x00000] in <filename unknown>:0

At Socketserver.listen () [0x00000] in <filename unknown>:0

The relevant code is as follows:

1. Using socketserver.startlistening () to start the socket (TCP) service and listen monitoring
