MAC address in Compact Framework

问题

How can I get the MAC Address using only the compact framework?

回答1:

1.4 of the OpenNETCF code gets the information from the following P/Invoke call:

    [DllImport ("iphlpapi.dll", SetLastError=true)]
    public static extern int GetAdaptersInfo( byte[] ip, ref int size );

The physical address (returned as MAC address) I think is around about index 400 - 408 of the byte array after the call. So you can just use that directly if you don't want to use OpenNETCF (why though? OpenNETCF rocks more than stone henge!)

Wonderful P/Invoke.net gives a full example here.

Oh and to properly answer your question:

only using the Compact Framework

You cant. That's life with CF, if you want some fun try sending data with a socket synchronously with a timeout. :D

Did none of those help?

Two out of three point to OpenNETCF as a way to do it.

Add a reference to System.Management.dll and use something like:

Dim mc As System.Management.ManagementClass
Dim mo As ManagementObject
mc = New ManagementClass("Win32_NetworkAdapterConfiguration")
Dim moc As ManagementObjectCollection = mc.GetInstances()
For Each mo In moc
    If mo.Item("IPEnabled") = True Then
        ListBox1.Items.Add("MAC address " & mo.Item("MacAddress").ToString())
    End If
Next

If you can access the registry, try to find your adapter MAC Address under the LOCAL_MACHINE\Comm\PCI\***\Parms\MacAddress.

It may be a quick and dirty solution that doesn't involve the use of WMI or OpenNETCF ...
