Hello. I have been using arduino yun for few days. Prevously i had arduino uno r3 and used it to read analogs via USB.
My question is :
Is there any way to connect the arduino yun with the laptop using ip and port (LAN) ?
I am using VisualStudio2010 and would like to receive a data from the yun (analog) in my program.
thanks for your help

http://myArduinoYun.local/arduino/digital/13 : calls digitalRead(13);
http://myArduinoYun.local/arduino/digital/13/1 : calls digitalWrite(13,1);
http://myArduinoYun.local/arduino/analog/9/123 : analogWrite(9,123);
http://myArduinoYun.local/arduino/analog/2 : analogRead(2);
Thanks for your answer sonnyyu.
Unfortunately It does not solve my problem. 
The point is that I need to receive data from the Arduino YUN through the ip using PC programm.
Example:
Arduino YUN ( ip : 192.168.1.200 ) ---------sending analogRead(x) --> Visual Studio_PC( ip : 192.168.1.999 )
Visual Studio_PC( ip : 192.168.1.199 ) -------- ok YUN thanks ! -----> Arduino YUN ( ip : 192.168.1.200 )
I do not want to use any of the http browsers to read the analog, unless it is the last chance to get any info from the YUN.
I would appreciate any code explaining how to send a data from the Arduino YUN to specific adress IP.
Thank you for your help 
One click away.
var client = new HttpClient();
var response = client.Get("http://myArduinoYun.local/arduino/analog/2");
analogRead(2).
If You would like to setup RESt Service API at .NET, and Consume RESt API from Yun.
Consume .NET RESt API from Arduino
Yun HTTP Client
void loop() {
HttpClient client;
client.get(dotnetwebserviceURI);
while (client.available()) {
char c = client.read();
Serial.print(c);
}
Serial.flush();
delay(5000);
}
Thank you sonnyyu for your replay. Your post was very helpful. I managed to get a flow data through the WiFi.
Nevertheless, I would have one more question connected with the the data transmission speed.
While Arduino gets : http://arduino.local/arduino/analog/1
it returns value of the analogs in the format : 1024,1024,1024,1024,1024 ( client.print(values) )
In my C# application I am downloading http text and breaking this up text for 5 peaces.
string value = client.DownloadString("http://arduino.local/arduino/analog/1");
The problem is that it takes too much time to get this data from the http. Wifi signal strength is 98%.
Estimated time to get the data from http is 300-500ms. In comparison with the USB data flow - which takes 1,3 ms - the Arduino YUN WiFi speed is very poor.
What would You recon to make it faster. Thank You for your help. 
My guess the slowness come from bridge, however to reach response time as low as 1 ms the Web Restful service will be fail. Since it build on http protocol, it is stateless protocol.
Solution:
WebSockets are a bi-directional, full-duplex, persistent connection from a client to a server. Once a WebSocket connection is established the connection stays open until the client or server decides to close this connection. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient as well as fast.

Thank You sonnyyu for your help.
Your idea will definitely do the job.
Node.js looks like a python programming.
I am using quite advanced c# application and switching into the different application would be a daunting task.
I have already created app using socket and ip commnuication.
Do you have any arduino yun server example, how to send some data using ip and port ? Or how to work with the websockets ? ( sending and receiving data )

not standard socket app but WebSockets app.
