Get Only MAC Address with VB.NET?

_{Thursday, January 27, 2011 2:49 PM}

Private Shared Function GetMacAddress() As String
   Dim qstring As String = "SELECT * FROM Win32_NetworkAdapterConfiguration where IPEnabled = true"
   For Each mo As System.Management.ManagementObject In New
System.Management.ManagementObjectSearcher(qstring).Get()
  Dim macaddress As String = mo("MacAddress")
  If Not macaddress Is Nothing Then
     Return macaddress
  End If
  Next
  Return ""
End Function 

i got those code somewhere, but i cant use it, i mean i want the result of mac address in textbox.

so i have one form with one textbox and one button, when i click this button, the MacAddress will show up in the textbox. how can i do that?

thanks

There's managed way of getting MAC address of a specific network adapter by means of System.Net.NetworkInformation.NetworkInterface.

Imports System.Net.NetworkInformation

** Function getMacAddress()
        Dim nics() As NetworkInterface = _
              NetworkInterface.GetAllNetworkInterfaces
        Return nics(0).GetPhysicalAddress.ToString
End Function**

Just call getMacAddress to get first network adapter's mac address which is usually the active one. Or you can loop through "nics" array to get other network adapters, as well.

HTH.

TextBox1.Text = GetMacAddress() should work.
