How can I terminate a TCP connection which is not handled by my program?
for example I want to close all the connection on port 10202 and I don't want them to reopen, but I want to allow the other ports. everything in C#.
like Sysinternals' tcpView does
You'd have to p/Invoke SetTcpEntry
. TCPView uses Dark and Mysterious Methods to do the same even on platforms that don't support that function.
