套接字代码示例 [ ^ ]



在那里你可以找到同步和异步客户端和服务器的代码示例。

在您的情况下，我猜这个异步示例最适合。

您将使用这些方法而不是使用自己的线程例如，BeginReceive和EndReceive。



我过去自己在这段代码上构建了应用程序。您总是需要根据需要更改代码，但这是一个很好的例子。

Actually i had developed client server one-way commucation.it's working fine after that

i had developed two-way communcation.i will explain one-way and two-way communcation

For suppose client send one Request(message) like "HI" then server listening the request

and it's shows "Hi" measge on server side then at the time server not responding client

request.it's only take user request show on server side only.this is one-way

communcation but whenever server responding for client request like "Hello" then called

two-way communcation.my project not working two-way communication.really tell u

minium it's not working one-way communcation(client request will not send to server)

in my project also.

}

above both applications are running same machine

clientside udp socket program and serverside udp socket program are same due to both

applications are runing on same machine.if the applications are running on different

machines then The source code will be identical except for IP address specified in the

RunClientThread( ) in serverside udp socket program.i think my code is correct.if any

wrong logic will be there pls modify the code.



if u want to any reference(not .dll) to the project .pls tell me ur mailid. i will

forward the client-server pdf.i had developed the project based on client-server pdf

can u please solve me for two-way communcation?


thank u.

I recommend that you take a look at this information, freely available on MSDN.

Socket Code Examples[^]

There you can find code examples for both synchronous and asynchronous client and server.
In your case I guess the asynchronous example is best suited.
Instead of using your own thread you will use the methods BeginReceive and EndReceive, for example.

I have built applications on this code myself in the past. You always have to change the code to your needs, but it is a good example to start with.
