主题：谁知道获取电脑网卡MAC地址和计算机名称的语句是什么？

 代码

Dim query As System.Management.ManagementObjectSearcher = New System.Management.ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration")
Dim queryCollection As System.Management.ManagementObjectCollection = query.Get()
Dim mo As New System.Management.ManagementObject
For Each mo In queryCollection
    If Convert.ToBoolean(mo("ipEnabled")) = True
        If mo("IPAddress") IsNot Nothing Then          
            MessageBox.Show( mo("IPAddress")(0))
        End If
    End If
Next

Dim query As System.Management.ManagementObjectSearcher = New System.Management.ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration")
Dim queryCollection As System.Management.ManagementObjectCollection = query.Get()
Dim mo As New System.Management.ManagementObject
For Each mo In queryCollection
    If IsDBNull(mo.Item("macaddress")) = False Then
        If mo.Item("macaddress") <> "" Then
           output.show(mo.Item("macaddress"))
        End If
    End If
Next

Dim nics() As System.Net.NetworkInformation.NetworkInterface = System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces
For Each nic As object In nics
    output.Show(nic.name)
    output.show(nic.NetworkInterfaceType)
    output.show(nic.Speed / 1000 / 1000 & "MB")
    output.show(nic.GetPhysicalAddress.tostring)
    output.show("----------------")
Next

Select * from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE

如何用上面这句查询MAC地址呢，我看有些VB代码是用的这个查询  但是在狐表中运行却提示无法找到Win32_NetworkAdapterConfiguration
