vb.net获取本地连接的mac地址

Private Sub Form_Load()

Dim strComputer As String

Dim objWMI As Object

Dim colIP As Object

Dim IP As Object

Dim I As Integer

strComputer = "."

Set objWMI = GetObject("winmgmts://" strComputer "/root/cimv2")

Set colIP = objWMI.ExecQuery _

("Select * from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE")

For Each IP In colIP

If Not IsNull(IP.IPAddress) Then

For I = LBound(IP.IPAddress) To UBound(IP.IPAddress)

MsgBox "IP地址:" IP.IPAddress(I) Chr(10) _

"网卡类型:" IP.Description(I) Chr(10) _

"网卡地址:" IP.Macaddress(I)

Next
