How to get MAC Address of client?

I am trying to get the MAC address of the client pc but it shows the mac address of the IIS server where my project is hosted.
protected void Page_Load(object sender, EventArgs e)
{
NetworkInterface[] anics = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in anics)
{
if (amacaddress == String.Empty)
{
IPInterfaceProperties properties = adapter.GetIPProperties();
amacaddress = adapter.GetPhysicalAddress().ToString();
lblname.Visible = true;
string ip = Request.UserHostAddress;
lblname.Text = "MAC Address is :- " + amacaddress + " "+ ip;
}
}
}

Yeah. That is similar to asking for getting the IMSI of a phone from a phone call - not possible, you call a phone number, the rest is implementation detail. MAC Addresses pretty much never travel more than one ethernet domain (next switch/router). They are not pat of the IP protocol layer. As such, you can not get them from the http request, which ultimatly is a TCP thus an IP connection. YOu will have to execute (C#, not javascript) code on the client to possibly get the local MAC AddressES - that is plural, there may be more than one (as in: 2 local network cards, a wireless adapter = 3 mac addresses).

Find ip of certain windows phone device in your local network

I'm trying to build C# app (desktop,windows, it doesn't really matter for now), with which I would like to connect to my windows phone, using sockets, to transfer some data... I know how this can be achieved,.
When connecting through sockets I don't want to manually enter windows phone device's IP address. So I want to know if it is possible to send some HTTP request from Windows phone app with some message, and fetch that message on computer, to be sure which IP is windows phone's IP?
In other words how to know which IP address belongs to Windows phone's IP address from Bunch of Ip addresses of devices on network?

Fallow this Link from Here
Add NameSpace :
using Windows.Networking;
public static string FindIPAddress()
{
List<string> ipAddresses = new List<string>();
var hostnames = NetworkInformation.GetHostNames();
foreach (var hn in hostnames)
{
//IanaInterfaceType == 71 => Wifi
//IanaInterfaceType == 6 => Ethernet (Emulator)
if (hn.IPInformation != null &&
(hn.IPInformation.NetworkAdapter.IanaInterfaceType == 71
|| hn.IPInformation.NetworkAdapter.IanaInterfaceType == 6))
{
string ipAddress = hn.DisplayName;
ipAddresses.Add(ipAddress);
}
}
if (ipAddresses.Count < 1)
{
return null;
}
else if (ipAddresses.Count == 1)
{
return ipAddresses[0];
}
else
{
//if multiple suitable address were found use the last one
//(regularly the external interface of an emulated device)
return ipAddresses[ipAddresses.Count - 1];
}
}
Edit:
If I am wrong You want to get particular Windows Phone IP address from bunch of IP addresses. AFAIK you can't get like this. But I suggest you to Append some string when getting IP of Windows Phone like below which will vary from other Ip addresses by looking it self.
string IPadd = FindIPAddress();
string WPIPadd = IPadd + " - Windows phone "
MessageDialog.show(WPIPadd);
If you find any thing new apart from this Let us know. Thanks

Get RSSI from an iBeacon estimote in c#

I'm trying to locate the distance from my computer and an iBeacon using bluetooth connection and getting the rssi. It's my first time using bluetooth in my apps and I'm something lost.
I downloaded the "32 feet" library (http://32feet.codeplex.com/) to use bluetooth functions, but I can't do this to work... This is the code I have:
BluetoothClient b = new BluetoothClient();
BluetoothDeviceInfo[] devices = b.DiscoverDevices();
BluetoothDeviceInfo info = devices.ElementAt(0);
// the first element it's the estimote
System.Windows.Forms.MessageBox.Show("Device name: " + info.DeviceName+"\n");
if (info.Connected)
{
System.Windows.Forms.MessageBox.Show("Connected\n");
}
else
{
System.Windows.Forms.MessageBox.Show("Not connected\n");
}
if (info.Authenticated)
{
System.Windows.Forms.MessageBox.Show("Authenticated\n");
}
else
{
System.Windows.Forms.MessageBox.Show("Not Authenticated\n");
}
System.Windows.Forms.MessageBox.Show("RSSI: " + info.Rssi + "\n");
The output is: Device name: estimote. Not connected. Authenticated. RSSI: -2147483648 (the minimum int?)
Thanks for your help.

This is Wojtek Borowicz, I'm a community evangelist at Estimote.
Unfortunately, RSSI is currently still not available for most of the Windows Bluetooth stacks.

Hostname scanning in C#

Iv'e recently started a new job as an ICT Technician and im creating an Console application which will consists of stuff that will help our daily tools!
My first tool is a Network Scanner, Our system currently runs on Vanilla and Asset tags but the only way we can find the hostname / ip address is by going into the Windows Console tools and nslookup which to me can be improved
I want to create an application in which I enter a 6 digit number and the application will search the whole DNS for a possible match!
Our hostsnames are like so
ICTLN-D006609-edw.srv.internal the d 006609 would be the asset tag for that computer.
I wish to enter that into the Console Application and it search through every hostname and the ones that contain the entered asset tag within the string will be returned along with an ip and full computer name ready for VNC / Remote Desktop.
Firstly how would I go about building this, shall i start the project of as a console app or a WPF. can you provide an example of how I can scan the hostnames via C#, or if there's an opensource C# version can you provide a link.
Any information would be a great help as it will take out alot of issues in the workpalce as we have to ask the customer to go into there My Computer adn properties etc and then read the Computer name back to use which I find pointless.
Regards.

I would actually go about this with PowerShell, since automating tasks is kinda its thing. In fact, here's a PowerShell script to list out all computers visible on the network. This is easily translatable into C# if you really want it there instead.
function Find-Computer( [string]$assetTag ) {
$searcher = New-Object System.DirectoryServices.DirectorySearcher;
$searcher.SearchRoot = New-Object System.DirectoryServices.DirectoryEntry;
$searcher.SearchScope = 'Subtree';
$searcher.PageSize = 1000;
$searcher.Filter = '(objectCategory=computer)';
$results = $searcher.FindAll();
$computers = #();
foreach($result in $results) {
$computers += $result.GetDirectoryEntry();
}
$results.Dispose(); #Explicitly needed to free resources.
$computers |? { $_.Name -match $assetTag }
}

Here's a way you can accomplish this, although it's not the best. You might consider hitting Active Directory to find the legitimate machines on your network. The code below shows how you might resolve a machine name, and shows how to ping it:
static void Main()
{
for (int index = 0; index < 999999; index++)
{
string computerName = string.Format("ICTLN-D{0:000000}-edw.srv.internal", index);
string fqdn = computerName;
try
{
fqdn = Dns.GetHostEntry(computerName).HostName;
}
catch (SocketException exception)
{
Console.WriteLine(">>Computer not found: " + computerName + " - " + exception.Message);
}
using (Ping ping = new Ping())
{
PingReply reply = ping.Send(fqdn);
if (reply.Status == IPStatus.Success)
{
Console.WriteLine(">>Computer is alive: " + computerName);
}
else
{
Console.WriteLine(">>Computer did not respond to ping: " + computerName);
}
}
}
}
Hope that helps...

Mute/unmute, Change master volume in Windows 7 x64 with C#

How can I adjust master volume in Windows 7 with C#?
I have seen an excellent implementation using winmm.dll here, but it works with XP and not with Windows 7.

I used the nuget package Naudio successfully with this code:
public void SetVolume(int level)
{
try
{
//Instantiate an Enumerator to find audio devices
NAudio.CoreAudioApi.MMDeviceEnumerator MMDE = new NAudio.CoreAudioApi.MMDeviceEnumerator();
//Get all the devices, no matter what condition or status
NAudio.CoreAudioApi.MMDeviceCollection DevCol = MMDE.EnumerateAudioEndPoints(NAudio.CoreAudioApi.DataFlow.All, NAudio.CoreAudioApi.DeviceState.All);
//Loop through all devices
foreach (NAudio.CoreAudioApi.MMDevice dev in DevCol)
{
try
{
if (dev.State == NAudio.CoreAudioApi.DeviceState.Active)
{
var newVolume = (float)Math.Max(Math.Min(level, 100),0) / (float)100;
//Set at maximum volume
dev.AudioEndpointVolume.MasterVolumeLevelScalar = newVolume;
dev.AudioEndpointVolume.Mute = level == 0;
//Get its audio volume
_log.Info("Volume of " + dev.FriendlyName + " is " + dev.AudioEndpointVolume.MasterVolumeLevelScalar.ToString());
}
else
{
_log.Debug("Ignoring device " + dev.FriendlyName + " with state " + dev.State);
}
}
catch (Exception ex)
{
//Do something with exception when an audio endpoint could not be muted
_log.Warn(dev.FriendlyName + " could not be muted with error " + ex);
}
}
}
catch (Exception ex)
{
//When something happend that prevent us to iterate through the devices
_log.Warn("Could not enumerate devices due to an excepion: " + ex.Message);
}
}

CodeProject has a very good sample here. Note that it relies on COM interop completely (check COM interface like IAudioEndpointVolume and IAudioMeterInformation on MSDN if you are interested in implementation details), and works ONLY for Vista/Win7 and higher.
