获得网卡MAC地址和IP地址

   Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim Wmi As New System.Management.ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration")

        TextBox1.Text = ""

        For Each WmiObj As ManagementObject In Wmi.Get

            If CBool(WmiObj("IPEnabled")) Then

                TextBox1.Text += "IP(" & WmiObj("IPAddress")(0) & ")|MAC(" & WmiObj("MACAddress") & ")" & vbCrLf

            End If

        Next

    End Sub

    如果有人运行不出来的话==>首先，引用System.Management；然后在代码中Imports System.Management；
