vb.net 获取指定网卡的网络连接状态

.net不能获得【指定】网卡的信息，给个思路，先遍历所有网卡，然后找到你需要的的那个网卡的信息。

电脑有两张网卡。如何用vb.net分别获取网卡的IP?求大神明路！

'要使得引用System.Management有效，先通过菜单

'[项目]--[添加引用]，在“.Net”选项卡里，选择“System.Management”，单击[确定]

Imports System.Management

Public Class Form1

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

Dim MySearcher As New ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration")

For Each MySearcherObj As ManagementObject In MySearcher.Get

If CBool(MySearcherObj("IPEnabled")) Then

MsgBox(MySearcherObj("IPAddress")(0))

End If

Next

End Sub

End Class
