tcpclient

I'm creating simple proxy server but I faced a strange situation, I've following code : var clientRequestStream = _tcpClient.GetStream(); var requestHeader = clientRequestStream.GetUtf8String(); GetUtf8String is a extension method for Stream class which reads stream (contains HttpRequest headers). I need to extract those headers to access Host and Requested Url. Once reading NetworkStream is done. I need to perform seek operation and set its clientRequestStream.Position = 0; because I've to read that stream and write it on another remote NetworkStream . I don't know how should I solve this

I've got a communication system based on TcpClient, and it works great except for when it's doing HTTPS to a particular IP. Then it starts to fail. By using a browser or HttpWebRequest, I have no problems doing HTTPS to that IP. I've created a test program to narrow my problem down to its basic essence, you can have a look at it here if you want: TestViaTcp That test program works perfectly for basic HTTP to the same IP, it always produces a successful response to the request. I put it in a loop, trigger it with a keypress, it will continue to succeed all day long. As soon as I toggle the

I am facing a big issue in TCP client application return in c#. Normal case it's working fine but in some case server send simultaneous response to a particular client, so this case all the simultaneous response are received as a single message in client side.So this case client failed to identify individual message. So such a case my client application failed to handle a particular activity. Is it possible to read as individual message in client side ?. So for solving this issue, I have some choices but i don't know if it is correct way. 1- Using a fixed length buffer in client side(But my

I have multiple instances of a client application, connecting to a main application over internet by TcpClient. (Both coded by me). So the connection is made like: TcpClient.Connect(ip, port) I now want this to handle various type of disconnect events: Main App (server) or a client app computer lose internet connection. On resume of connection, the communication seems lost, but when I try to reconnect, I get message: "A connection request was made on an already connected socket" So I need to close and restart the client app. Main App (server) is closed, and restarted. Restarting the Main App,

This question already has an answer here: C# network connection running from shared drive 1 answer I asked a similar question to this a few days ago. At that point, I was trying to use sockets. Currently, I am using TCPClient to do the dirty socket work for me. I am using Windows 7 and Visual studios 2013 Professional. Original and Current Project Outline: I need to create an application (WinForms using C#) that allows the user to connect to a device (a piece of hardware that will be sent arguments/commands) via wifi (wifi is end goal but I am settling at the moment for any connection) and

The MSDN documentation clearly states that: After obtaining the NetworkStream, you can call the EndWrite method to successfully complete the send operation and return the number of bytes sent. Emphasis mine. However, it returns nothing (void): public override void EndWrite( IAsyncResult asyncResult ) Am I missing something, or is this a typo ( EndRead() does return bytes read).? You are not missing anything, it is a doc bug. Probably induced by copy/pasting the EndRead article. Where it very much does matter. You already know how many bytes were written, all of them. 来源： https://stackoverflow

I am trying to run a UNIX command on remote host from my C# application. I have seen various post over internet including SO for doing this using various libraries like SmartSsh any many others. And some others using command line commands. I do not want to use any third party library. Hence I tried using TcpClient class with example shown here on MSDN . I am passing hostname as : user@servername and port 22 . When I run this code it trows an exception SocketException (0x80004005): No such host is known at System.Net.Sockets.TcpClient..ctor(String hostname, Int32 port) Is it because my server

I'm writing a small (C#) client application that sends data using a TCP/IP connection to a remote server. I'm using the standard .Net TcpClient object and want to leave the connection open from the client end as I am regularly submitting data packets to the server. However, it is possible that the server may close the connection, in which case I need to know to re-connect before sending my next packet. Using Wireshark, I can see (only) the following dialogue when the server terminates the connection: server >>> FIN, ACK ACK <<< client What I do not see is my client responding with a FIN of its
