c# - How can I add SSL encryption to available TCP/IP socket -


i going upgrade system used tcp connection without ssl. want add ssl encryption current connection without changing in code. there in code.

ipaddress ipaddress = ipaddress.parse(ipaddress); ipendpoint remoteep = new ipendpoint(ipaddress, port);  // create tcp/ip socket. var client = new socket(addressfamily.internetwork, sockettype.stream, protocoltype.tcp);  client.beginconnect(remoteep,new asynccallback(connectcallback), client);

what tried this,

ipaddress ipaddress = ipaddress.parse(ipaddress); ipendpoint remoteep = new ipendpoint(ipaddress, port);  // create tcp/ip socket. var client = new socket(addressfamily.internetwork, sockettype.stream, protocoltype.tcp);  client.beginconnect(remoteep, new asynccallback(connectcallback), client); while (!client.connected) { } networkstream stream = new networkstream(client); sslstream ssl = new sslstream(stream, false, validateservercertificate);

but not doing need. @ least validateservercertificate delegate not called.
what's wrong code?

important
cannot remove socket named client during change because affect lot of other codes.
