tcpclient

I tried to understand the MSDN example for NetworkStream.EndRead(). There are some parts that i do not understand. So here is the example (copied from MSDN ): // Example of EndRead, DataAvailable and BeginRead. public static void myReadCallBack(IAsyncResult ar ){ NetworkStream myNetworkStream = (NetworkStream)ar.AsyncState; byte[] myReadBuffer = new byte[1024]; String myCompleteMessage = ""; int numberOfBytesRead; numberOfBytesRead = myNetworkStream.EndRead(ar); myCompleteMessage = String.Concat(myCompleteMessage, Encoding.ASCII.GetString(myReadBuffer, 0, numberOfBytesRead)); // message

Is there a way to configure the timeout in which a socket expects to receive an ACK for sent data before it decides that the connection has failed? I'm aware this can be done at the application level as well, but since every packet I send is ACK'd anyway, and I just want to know if my data is received, using additional data at the application level to accomplish the same thing seems wasteful. (Not to mention, my particular application uses per-byte charged cellular links.) Note: As per my previous question -- What conditions cause NetworkStream.Write to block? -- you cannot rely on .Write

HTTP proxy support in .NET does not actually support the lower level classes like TcpClient or Socket. But I want to connect a TCPServer (ip, port) through HTTP proxy that support 'CONNECT' command. So I need to do the following steps: Connect to proxy. Send CONNECT Host:Port HTTP/1.1<CR><LF> Send <CR><LF> Wait for a line of response. If it contains HTTP/1.X 200 , the connection is successful. Read further lines of response until receive an empty line. It's connected to the outside world through a proxy. Any data exchange as posssible with proxy. Actually I do this without proxy TcpClient

I just asked a question on how to send data larger than the SendBufferSize and the answer was that is would be send in a couple of parts. My second question is how will this data be received? Will it be complete in the network stream or will it get it divided. the first question: Can you send a file larger that the SendBufferSize throuh a TcpClient? TCP is not a message only protocol. It is a stream based protocol and takes care of splitting the data for us. Lemme take you to the core section. There are two parts in the case of TCP - Segmentation and Fragmentation. Segmentation happens at TCP

I have a separate thread on both client and server that are reading/writing data to/from a socket. I am using synchronous TcpClient im (as suggested in documention): https://msdn.microsoft.com/cs-cz/library/system.net.sockets.tcpclient%28v=vs.110%29.aspx When connection is closed .Read()/.Write() throws an exception. Does it mean that when .Write() method does not throw the data were delivered correctly to the other party or do I need to implement custom ACK logic ? I read documentation for both Socket and TcpClient class and none of them describe this case. All that a returning send() call

How can I detect when a client disconnects from the TcpListener ? Each of my clients is handled in a separate thread. Look at NetworkStream.Read , or depending on what you are using in your code maybe TCPClient.GetStream is more appropriate, but basically the same answer. From the docs: This method reads data into the buffer parameter and returns the number of bytes successfully read. If no data is available for reading, the Read method returns 0. The Read operation reads as much data as is available, up to the number of bytes specified by the size parameter. If the remote host shuts down the
