udpclient

问题 First I want to say that I read: UdpClient, Receive() right after Send() does not work? My question is: is this the normal standard way to handle UDP communications. Set up one UdpClient for send and another for receive? 回答1: Yes. This is the standard way to do UDP sockets in .NET 回答2: you can actually do this on a Server using Sockets as well checkout this link to see if this will help you in anyway.how to configure the server socket 来源： https://stackoverflow.com/questions/8933223/udpclient

问题 When i try to send a message from my client , the server is not able to receive that message and print it. Can anyone tell me the error in the following server client application. I have created two WinForm projects, one is UDP server and the other is UDP client. In UDP server project, I created a form which contains a RichTextBox named richTextBox1 to show message and a Button named btStart to start/stop the listening. This is the code snippet: using System; using System.Collections.Generic;

问题 So I'm trying to make a very simple system to send messages from a client to a server (and later on from server to client as well, but baby steps first). I'm not sure exactly how to use UDPClient to send and receive messages (especially to receive them), mostly because I don't have anything triggering the ReceiveMessage() function and I'm not sure what would. Source Code is at this link, go to File>Download. It is already built if you want to just run the exe. So my question is basically: How

问题 I'm having troubles with UdpClient in C#. I am streaming audio over the internet between two clients. On my microphone, with a sample rate of 16khz, I send UDP packets with audio with 6400 byte per packet. These never get through, except the last packet which is usally around 1200-3400 something since I close the recording. When I lower sample rate to 8khz, I send packets with 3200 byte payload. These always get through for some reason. So basically anything above 3200 gets botched (havn't

问题 If I create a socket using var socket = new UdpClient(0,AddressFamily.InterNetwork); How do I then find the port of the socket? I'm probably being daft, but I'm not having luck in MSDN/Google (probably because it is 4:42 on a Friday and the sun is shining). Background: What I want to do is find an open port, and then report to another process to forward messages to me on that port. There may be multiple clients, so I don't want to used a fixed port. Thanks. 回答1: UdpClient is a wrapper around

问题 The following code, despite apparently closing the UDP Socket, leaves it hanging and unable to reconnect to the same address / port. These are the class variables I use: Thread t_listener; List<string> XSensAvailablePorts; private volatile bool stopT_listener = false; volatile UdpClient listener; IPEndPoint groupEP; I create and launch a new thread with a method which will handle the Socket connection and listening: private void startSocketButton_Click(object sender, RoutedEventArgs e) {

问题 This is maybe a stupid question, but since I am relatively new to UDP here it goes... If I am having two separate byte arrays that I need the receiving side to get as one big array, for example: byte[] Array1 = {1,1,1} byte[] Array2 = {2,2,2} Can I avoid having to create a buffer and copy each array into it, and then send that buffer, like this: byte[] Buffer= new byte[Array1.Length + Array2.Length]; Buffer.BlockCopy(Array1, 0, Buffer, 0, Array1.Length); Buffer.BlockCopy(Array2, 0, Buffer,

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago . I want to check if the upd port for OpenVPN is open. For Tcp Port it was really simple, but now I struggle with Udp ports. This is my TCP Implementation private static bool TestConnectionInternal(string hostname, int port, int timeOutMs, int maxTries, int count) { using (var

问题 I am upgrading an older version of Delphi to XE5, The older version uses Indy Component UDPClient, XE5 says SendBuffer cannot be called with these arguments. Will someone please help me. Here is sample code snippet: var i: integer; begin i := bpt; if i <> 0 begin //send Reset byte myBuff[i] := chr(_reset); // reboot the LIA inc(i); IdUDPClient1.SendBuffer(myBuff,i); end; end; where myBuff : array[0..255] of char; Thank you in advance for your help.

问题 I am implementing a UDP data transfer thing. I have several questions about UDP buffer. I am using UDPClient to do the UDP send / receive. and my broadband bandwidth is 150KB/s (bytes/s, not bps ). I send out a 500B datagram out to 27 hosts 27 hosts send back 10KB datagram back if they receive. So, I should receive 27 responses, right? however, I only get averagely 8 - 12 instead. I then tried to reduce the size of the response down to 500B, yes, I receive all. A thought of mine is that if
