您是在嗅探,还是只想连接到设备并获取数据?如果是后者,您可以使用 TcpClient 类来做您需要的事情。
using System.Net.Sockets;
TcpClient tcp = new TcpClient(AddressFamily.InterNetwork);
tcp.Connect(IPAddress.Parse("192.168.0.1"), 12345);
然后tcp.GetStream()
会给你一些你可以输入你选择的 XML 解析器的东西。
编辑:这是一个更详细的示例。
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;
using System.Net.Sockets;
using System.Threading;
namespace ConsoleApplication1 {
class XMLBlaster {
Thread myThread;
public XMLBlaster() {
myThread = new Thread(Start);
}
public void Begin() {
myThread.Start();
}
//This will listen for a connection on port 12345, and send a tiny XML document
//to the first person to connect.
protected void Start() {
TcpListener tcp = new TcpListener(IPAddress.Any, 12345);
tcp.Start(1);
TcpClient client = tcp.AcceptTcpClient();
StreamWriter data = new StreamWriter(client.GetStream());
data.Write("<myxmldocument><node1><node2></node2></node1></myxmldocument>");
data.Close();
client.Close();
}
}
class Program {
static void Main(string[] args) {
//this sets up the server we will be reading
XMLBlaster server = new XMLBlaster();
server.Begin();
//this is the important bit
//First, create the client
TcpClient tcp = new TcpClient(AddressFamily.InterNetwork);
//Next, connect to the server. You probably will want to use the prober settings here
tcp.Connect(IPAddress.Loopback, 12345);
//Since byte manipulation is ugly, let's turn it into strings
StreamReader data_in = new StreamReader(tcp.GetStream());
//And, just read everything the server has to say
Console.WriteLine(data_in.ReadToEnd());
//when we're done, close up shop.
data_in.Close();
tcp.Close();
//this is just to pause the console so you can see what's going on.
Console.WriteLine("Press any key to continue...");
Console.ReadKey(false);
}
}
}
请注意,这忽略了您需要遵循的任何协议的问题(例如,如果您通过 HTTP(端口 80)进行通信,则在获取数据之前与服务器通信涉及很多工作(并且,还有另一个类这样做正确;))
