Hi friends, I am working on get MAC Address, following code returns MAC Address,

now i want the MAC address of other system where it is access, pls help me,
I want to track MAC address from where application is accessed

public string getMACAddress()

{

ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");

ManagementObjectCollection moc = mc.GetInstances();

string MACAddress = String.Empty;

foreach (ManagementObject mo in moc)

{

if (MACAddress == String.Empty) // only return MAC Address from first card

{

if ((bool)mo["IPEnabled"] == true) MACAddress = mo["MacAddress"].ToString();

}

mo.Dispose();

}

MACAddress = MACAddress.Replace(":", "-");

return MACAddress;

}

you need to get MAC address by ip address like this

Hi please try like this

using System;

using System.Drawing;

using System.Collections;

using System.ComponentModel;

using System.Windows.Forms;

using System.Data;

using System.Net;

using System.DirectoryServices;

using System.Runtime.InteropServices;

namespace GetMacAddressFromIPAddress

{

public class GetMacAddressFromIPAddress

{

[DllImport("iphlpapi.dll", ExactSpelling=true)]

public static extern int SendARP( int DestIP, int SrcIP, [Out] byte[] pMacAddr, ref int PhyAddrLen );

public string GetMacAddress(string sName)

{

string s = string.Empty ;

System.Net.IPHostEntry Tempaddr = null;

Tempaddr = (System.Net.IPHostEntry)Dns.GetHostByName(sName);

System.Net.IPAddress[] TempAd = Tempaddr.AddressList;

string[] Ipaddr = new string[3];

foreach(IPAddress TempA in TempAd)

{

Ipaddr[1] = TempA.ToString();

byte[] ab = new byte[6];

int len = ab.Length;

int r = SendARP( (int) TempA.Address, 0, ab, ref len );

string sMAC = BitConverter.ToString( ab, 0, 6 );

Ipaddr[2] = sMAC;

s = sMAC;

}

return s;

}

ManagementObjectSearcher query1;
ManagementObjectCollection queryCollection1;
ManagementScope RemoteConn;

ObjectQuery oQuery = new ObjectQuery("Select MacAddress,IPAddress from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE");

ConnectionOptions options = new ConnectionOptions();
options.Username = sDomain + "\\" + sUserName; //could be in domain\user format
options.Password = sPwd;

try
{
RemoteConn = new ManagementScope("\\\\" + RemoteHost + "\\root\\cimv2",options);
query1 = new ManagementObjectSearche(RemoteConn,oQuery);
queryCollection1 = query1.Get();

foreach( ManagementObject mo in queryCollection1 )
{
int nrIP = ((System.Array)(mo["IPAddress"])).Length;

for(int c=0; c<nrIP; c++)
{
Console.WriteLine (RemoteHost + " Mac Address: " + mo["MacAddress"].ToString() );
Console.WriteLine (RemoteHost + " " + c +" IP Address: " + ((System.Array)(mo["IPAddress"])).GetValue(c));
}
}
}
catch (Exception e)
{
Console.WriteLine("Failed to connect to: " + RemoteHost + "\n Error Message: " + e.Message);
}

Hi,

You can use this code to find MAC id

Public Function GetMACAddress() As String

Dim mc As New ManagementClass("Win32_NetworkAdapterConfiguration")

Dim moc As ManagementObjectCollection = mc.GetInstances()

Dim MACAddress As String = [String].Empty

For Each mo As ManagementObject In moc

If MACAddress = [String].Empty Then

' only return MAC Address from first card

If CBool(mo("IPEnabled")) = True Then

MACAddress = mo("MacAddress").ToString()

End If

mo.Dispose()

Next

MACAddress = MACAddress.Replace(":", "")

Return MACAddress

End Function

hi

To view the MAC address we will be getting, we will need a simple web site that will allow us to display some data. At this point, I have created a new ASP.NET Empty Web Site and need to add in a Web Form with a label. To do this:

Right click the project in your Solution Explorer.
Select Add New Item…
Select a Web Form.
Name it Default.aspx.
Click Add.
Open Default.aspx up to Design mode.
Drag and drop a Label onto the Web Form.

Getting the MAC Address in C#
Next, we need to add some code that will grab the MAC address from the current computer and display it on the web page. To do this:

Open Default.aspx.cs up for editing.
At the top of the class add the following using statement:

The using statement we need for accessing NetworkInterfaces

using System.Net.NetworkInformation;

In the Page_Load event method add in the following code:

The code to display the MAC address.

protected void Page_Load(object sender, EventArgs e)

{

//get all nics

NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();

//display the physical address of the first nic in the array,

//which should correspond to our mac address

Label1.Text = nics[0].GetPhysicalAddress().ToString();

}

The MACAddress property of the http://msdn.microsoft.com/en-us/library/aa394217.aspx can provide you with an adapter's MAC address.

(System.Management Namespace)

f you're not familiar with the WMI API (Windows Management Instrumentation), there's a http://msdn.microsoft.com/en-us/library/bb404655.aspx for .NET apps.

WMI is available across all version of windows with the .Net runtime.

Here's a code example:

System.Management.ManagementClass mc = default(System.Management.ManagementClass);

ManagementObject mo = default(ManagementObject);

mc = new ManagementClass("Win32_NetworkAdapterConfiguration");

ManagementObjectCollection moc = mc.GetInstances();

foreach (var mo in moc) {

if (mo.Item("IPEnabled") == true) {

Adapter.Items.Add("MAC " + mo.Item("MacAddress").ToString());

}
