How to get MAC address of your system.

Author: Shahzad

This code sample shows you the way to find out the MAC address of the system. Microsoft.Net provides System.Management namespace to perform this task. With the help of Visual Basic.Net code it's easy.

Import the following namespace.

Imports System.Management

Declare following object variables.

Dim objMOS As ManagementObjectSearcher

Dim objMOC As Management.ManagementObjectCollection

Dim objMO As Management.ManagementObject

Execute the query.

objMOS = New ManagementObjectSearcher("Select * From Win32_NetworkAdapter")

objMOC = objMOS.Get

Get MAC address from the query result.

For Each objMO In objMOC

MessageBox.Show(objMO("MACAddress"))

Next

Dispose object variables.

objMOS.Dispose()

objMOS = Nothing

objMO.Dispose()

objMO = Nothing

Hi
The code what you gave is working but i need to generate only the mac id of the system and it shouldn't be running in a for loop.

How can this be done???With the Same Code
