WMI 應用——用 VBScript 編寫類似 ipconfig 的工具


作者：終南   <li.zhongnan@hotmail.com>



在Windows下，WSH的功能是非常強大的。WMI 則提供了非常豐富的介面，可以與系統進行互動，獲取系統相關資訊，並能對系統中的裝置和物件進行有效管理。


Windows中的ipconfig 工具提供了與系統網路裝置的介面，WMI 中同樣有相同的介面，因此可以利用 VBScript 編寫指令碼來實現類似 ipconfig 的功能。利用 WMI 介面可以實現的網路管理功能非常之多，此處僅以顯示IP地址、釋放和獲取DHCP地址為例做一說明：


1、顯示IP地址


通過 Win32_NetworkAdapterConfiguration 獲取網路配置資訊，判斷網路介面卡是否支援IP協議。然後利用Win32_NetworkAdapter 物件或取網路卡資訊，Win32_NetworkAdapter有很多屬性，重要的包括NetConnectionStatus、NetConnectionID、MACAddress、IPAddress等。所有ipconfig顯示出的資訊都能夠獲取得到，那麼需要做的工作就是按照 ipconfig 顯示格式來排列一下這些資訊，使其看起來好看些。


2、釋放和獲取DHCP地址


呼叫Win32_NetworkAdapterConfiguration物件的ReleaseDHCPLease()和RenewDHCPLease()方法來實現。


3、新增上幫助說明、整理一下指令碼的結構，於是就有了：
