WMI操作示例

利用WMI可以实现对本地及远程主机的信息获取及操作，本示例WMI的应用。

            System.Management.ConnectionOptions options = new ConnectionOptions();
            options.Username=@"lypower\Administrator";
            options.Password=@"your password here ";
            System.Management.ManagementScope ms = new ManagementScope(@"\\remoteIP\root\cimv2",options);
            
            //Get Local PC - ProcessorId : 
            //Win32_Processor    Win32_DiskDrive    Win32_NetworkAdapterConfiguration    Win32_OperatingSystem    
             ms = null;//if COMMENT this line(means you COMMENT all above), you get remote, else you get local information.
             System.Management.ObjectQuery query= new ObjectQuery("select * from Win32_Processor");
            System.Management.ManagementObjectSearcher mos = new ManagementObjectSearcher(ms,query);
            System.Management.ManagementObjectCollection moc = mos.Get();
            foreach(ManagementObject mo in moc)
            {
                Console.WriteLine(mo["ProcessorId"]);
            }

如上代码，注释掉ms=null 的行，上面的代码起作用，我们查询到RemoteServer的ProcessorId；
删除ms=null及其上面的所有行，并将ManagementObjectSearcher的ms参数去掉，可以查Local的ProcessorID。

类似的，我们可以查询很多对象，如上面代码绿色注释部分等，查询语句类似SQL，这里叫WQL。

我们用ManagementClass类可以更方便的查询本地信息，如下面代码

        /// <summary>
        /// 获取本机的Mac地址
        /// </summary>
        private string GetLocalMacAddress()
        {
            //网卡的MAC地址
            ManagementClass mcNetworkAdapterConfiguration = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection mocNetworkAdapterConfiguration = mcNetworkAdapterConfiguration.GetInstances();
            string strReturn = "";
            foreach (var mac in mocNetworkAdapterConfiguration)
            {
                if ((bool)mac["IPEnabled"])
                {
                    strReturn = string.Format("{0}\r\n", mac["MacAddress"]);
                }
            }
            return strReturn;
        }
