c# - TCP server with multiple Clients -

i working on tcp server/client application.

my question is:

my server application starts new thread , blocks until connection accepted listenforclient method

but how can manage connections when multiple clients connected server , request different things @ same time how can manage client 1 gets info need , same client 2.

it's multithreaded, multiple clients can connect how can process request. don't want put in 1 method would.

thanks in advance

your client dispatched in different threads, not intersect. need add "dispatchmethod" messages processed.

using system.text.regularexpressions; ...  if (regex.ismatch(bufferincmessage, properties.settings.default.reqlogin, regexoptions.ignorecase)) {     ... } else if (regex.ismatch(bufferincmessage, /*some of command1*/, regexoptions.ignorecase)) {     ... } else if (regex.ismatch(bufferincmessage, /*some of command1*/, regexoptions.ignorecase)) {     ... }
