为什么我不能在客户端socket上接收数据。解决方法方法c＃？ [英] Why I cant Recieve Data on Client Side socket.recieve method method c# ?
问题描述
我从服务器向客户端发送/接收文本。
我的服务器端代码就是这个。它的node.js，socket.io代码。在服务器端我收到客户端的数据..这部分工作对我来说很好..
I sending/Receiving text from Server to client.
my server side code is this. its node.js, socket.io code. on server side i receive data from client..this part work fine for me..
var app = require（'http'）。createServer（handler）
，io = require（'socket.io'）。listen（app）
，fs = require（' fs'）
app.listen（8070）;
var mysocket = 0;
函数处理程序（req，res）{
fs.readFile（__ dirname +'/ index.html'，
函数（错误，数据）{
if（err）{
res.writeHead（500）;
返回res.end（'错误加载index.html'）;
}
res.writeHead（200）;
res.end（data）;
}）;
}
io.sockets.on（'connection'，function（socket）{
socket.send（'hi'）;
console.log（'index.html connected' ）;
mysocket = socket;
}）;
/ / udp server on 41181
var dgram = require （dgram）;
var server = dgram.createSocket（udp4）;
server.on（message，function（msg，rinfo）{
console.log（msg：+ msg）;
if（mysocket！= 0）{
mysocket.emit（'field' ，+ msg）;
}
}）;
server.on（listening，function（）{
var address = server.address（）;
console.log（udp server listening+ address.address +：+ address.port）;
}）;
server.bind（41181）;
var app = require('http').createServer(handler)
, io = require('socket.io').listen(app)
, fs = require('fs')
app.listen(8070);
var mysocket = 0;
function handler (req, res) {
fs.readFile(__dirname + '/index.html',
function (err, data) {
if (err) {
res.writeHead(500);
return res.end('Error loading index.html');
}
res.writeHead(200);
res.end(data);
});
}
io.sockets.on('connection', function (socket) {
socket.send('hi');
console.log('index.html connected');
mysocket = socket;
});
//udp server on 41181
var dgram = require("dgram");
var server = dgram.createSocket("udp4");
server.on("message", function (msg, rinfo) {
console.log("msg: " + msg);
if (mysocket != 0){
mysocket.emit('field', ""+msg);
}
});
server.on("listening", function () {
var address = server.address();
console.log("udp server listening " + address.address + ":" + address.port);
});
server.bind(41181);
In上面的代码，你可以看到，我发送嘿，使用这个方法。
In Above Code you can see,i am sending "Hey" ,,using this mothod.
socket.send（'hi'）;
socket.send('hi');
这个文本我想在我的客户端接收..我在客户端用C＃写这个方法..
this Text I want Receive ON my Client Side.. I writing this Method in C# in my client side..
public static void RecieveUDP（int count）
{
Socket socket = new Socket（AddressFamily.InterNetwork，SocketType.Dgram ，ProtocolType.Udp）;
socket.Connect（127.0.0.1，41181）;
byte [] bytes = new byte [256]; //文本的长度Hello world！
//接收超时数据10s
for（int x = 0; x< count; x ++）
{
Console.WriteLine（socket.Receive（bytes）） ;
}
socket.Close（）;
}
public static void RecieveUDP(int count)
{
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
socket.Connect("127.0.0.1", 41181);
byte[] bytes = new byte[256]; // length of the text "Hello world!"
// receive data with timeout 10s
for (int x = 0; x < count; x++)
{
Console.WriteLine(socket.Receive(bytes));
}
socket.Close();
}
我没有收到任何文字。你可以帮我吗。
我能够从客户端c＃向服务器发送数据。只能在客户端接收文本..
谢谢提前。
I am not receiving any text . Can you help me Please.
I am able to send data from client side c# to Server .just can't receive text on client side..
Thanks Advance .
推荐答案
你应该打电话给
You should call e.g.
socket.Connect("127.0.0.1", 8888);
否则套接字未连接......
Otherwise the socket is not connected...
