网络接口速度
网络接口速度
提问于 2012-10-18 22:33:54
我想要获取网络接口的名称、速度和MAC地址。
var searcher = new ManagementObjectSearcher { Scope = GetConnectedScope(target, "cimv2") };
try
{
searcher.Query = new ObjectQuery("SELECT MACAddress, Speed, Name FROM Win32_NetworkAdapter");
var nicList = new List<NetworkInterfaceModel>();
foreach (var item in searcher.Get())
{
nicList.Add(new NetworkInterfaceModel
{
NetworkInterfaceName = (string)item["Name"],
NetworkInterfaceSpeed = (double)(item["Speed"] != null ? (ulong) item["Speed"] : 0)/1000/1000,
MacAddress = (string)item["MACAddress"]
});
}对于Windows7和Vista，它工作得很好，但对于XP和Windows Server2003，它没有达到这个速度。如何获得XP和Server 2003的速度？

根据http://msdn.microsoft.com/en-us/library/windows/desktop/aa394216(v=vs.85).aspx的说法，Win32_NetworkAdapter在XP下不支持speed属性：
Windows Server2003、Windows XP、Windows2000和Windows NT4.0:此属性尚未实现。默认情况下，它返回空值。
相反，请使用具有相同属性的CIM_NetworkAdapter类。

using System.Net;
foreach (NetworkInterface netInterface in NetworkInterface.GetAllNetworkInterfaces()) {
Debug.WriteLine(netInterface.Name); // Name
Debug.WriteLine(netInterface.Speed); // Speed
Debug.WriteLine(netInterface.GetPhysicalAddress().ToString()); // MAC

您可以使用windows cmd获取网络名称：
Process p = new Process();
p.StartInfo.FileName = "netsh.exe";
p.StartInfo.Arguments = "wlan show interfaces";
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.Start();
string s = p.StandardOutput.ReadToEnd();
string s1 = s.Substring(s.IndexOf("SSID"));
s1 = s1.Substring(s1.IndexOf(":"));
s1 = s1.Substring(2, s1.IndexOf("\n")).Trim();
p.WaitForExit();
namelabel.Text = s1;对于MAC地址：
IPAddress IP = IPAddress.Parse("192.168.1.1");
byte[] macAddr = new byte[6];
uint macAddrLen = (uint)macAddr.Length;
UInt32 nRet = 0;
uint nAddress = BitConverter.ToUInt32(IP.GetAddressBytes(), 0);
nRet = SendARP(nAddress, 0, macAddr, ref macAddrLen);
if (nRet == 0)
{
string[] sMacAddress = new string[(int)macAddrLen];
for (int i = 0; i < macAddrLen; i++)
{
sMacAddress[i] = macAddr[i].ToString("x2");
string macAddress += sMacAddress[i] + (i < macAddrLen - 1 ? ":" : "");
}
}关于速度，你可以使用下面的代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Net.NetworkInformation;首先添加一个timerInteval(您希望以多快的速度更改为新值)、一个NetworkInteface和一个计时器：
private const double timerUpdate = 1000;
private NetworkInterface[] nicArr;
private Timer timer;然后在启动时继续使用以下组件：
public Form1()
{
InitializeComponent();
InitializeNetworkInterface();
InitializeTimer();
}组件：
private void InitializeNetworkInterface()
{
// Grab all local interfaces to this computer
nicArr = NetworkInterface.GetAllNetworkInterfaces();
// Add each interface name to the combo box
for (int i = 0; i < nicArr.Length; i++)
comboBox1.Items.Add(nicArr[i].Name); //you add here the interface types in a combobox and select from here WiFi, ethernet etc...
// Change the initial selection to the first interface
comboBox1.SelectedIndex = 0;
}
private void InitializeTimer()
{
timer = new Timer();
timer.Interval = (int)timerUpdate;
timer.Tick += new EventHandler(timer_Tick);
timer.Start();
}定时器滴答声
void timer_Tick(object sender, EventArgs e)
{
UpdateNetworkInterface();
}使用此void更新ping：
public void UpdatePing()
{
try
{
Ping myPing = new Ping();
PingReply reply = myPing.Send(textBox1.Text, 1000);
if (reply != null)
{
label17.Text = reply.Status.ToString();
label18.Text = reply.RoundtripTime.ToString();
}
}
catch
{
label17.Text = "ERROR: You have Some TIMEOUT issue";
label18.Text = "ERROR: You have Some TIMEOUT issue";
}
}最后用这个来表示网络形式的速度：
private void UpdateNetworkInterface()
{
// Grab NetworkInterface object that describes the current interface
NetworkInterface nic = nicArr[comboBox1.SelectedIndex];
// Grab the stats for that interface
IPv4InterfaceStatistics interfaceStats = nic.GetIPv4Statistics();
// Calculate the speed of bytes going in and out
// NOTE: we could use something faster and more reliable than Windows Forms Tiemr
// such as HighPerformanceTimer http://www.m0interactive.com/archives/2006/12/21/high_resolution_timer_in_net_2_0.html
// Update the labels
speedlbl.Text = nic.Speed.ToString();
interfaceTypelbl.Text = nic.NetworkInterfaceType.ToString();
bytesReceivedlbl.Text = interfaceStats.BytesReceived.ToString();
bytesSentlbl.Text = interfaceStats.BytesSent.ToString();
int bytesSentSpeed = (int)(interfaceStats.BytesSent - double.Parse(label10.Text)) / 1024;
int bytesReceivedSpeed = (int)(interfaceStats.BytesReceived - double.Parse(label11.Text)) / 1024;
bytescomelbl.Text = bytesSentSpeed.ToString() + " KB/s";
bytessentlbl.Text = bytesReceivedSpeed.ToString() + " KB/s";
