C#利用WMI获取 远程计算机硬盘数据

一、利用WMI获取 远程计算机硬盘数据,先引入"System.Management.dll"文件。

　　　/// <summary>
        /// 获取存储服务器硬盘信息。
        /// </summary>
        /// <returns></returns>
        public Dictionary<string, string> GetDiskInfo()
        {
            Dictionary<string, string> dic = new Dictionary<string, string>();
            double free = 0;
            double used = 0;
            double total = 0;
            string name = string.Empty;
            //1024*1024*1024
            long GB = 1024 * 1024 * 1024;
            //设定生成的WMI所需的所有设置
            System.Management.ConnectionOptions Conn = new ConnectionOptions();
            //设定用于WMI连接操作的用户名
            Conn.Username = "Administrator";
            //设定用户的口令
            Conn.Password = "password"; 

            string IPaddress = "172.16.5.214";  //远程存储的IP
            //设定用于执行WMI操作的范围
            System.Management.ManagementScope Ms = new ManagementScope("\\\\" + IPaddress + "\\root\\cimv2", Conn);
            try
            {
                //连接到实际操作的WMI范围
                Ms.Connect();
                //设定通过WMI要查询的内容
                ObjectQuery Query = new ObjectQuery("select FreeSpace,Size,Name from Win32_LogicalDisk where DriveType=3");
                //ObjectQuery Query = new ObjectQuery("select * from Win32_LogicalDisk where deviceid='C:'");
                
                //WQL语句，设定的WMI查询内容和WMI的操作范围，检索WMI对象集合
                ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Ms, Query);

　　　　　  //----ManagementObjectSearcher managerSearch = new ManagementObjectSearcher(wqlObjectQuery);//获取本地磁盘--------
                //异步调用WMI查询
                ManagementObjectCollection ReturnCollection = Searcher.Get();
                //通过对产生的WMI的实例集合进行检索，获得硬盘信息
                foreach (ManagementObject Return in ReturnCollection)
                {
                    //注意盘符要有:号
                    string deviceid = "D:";
                    if (Return["Name"].ToString() == deviceid)
                    {
                        name = "磁盘名称：" + Return["Name"].ToString();
                        //硬盘的可用空间
                        free = Convert.ToDouble(Return["FreeSpace"]) / GB;
                        //硬盘的已用空间
                        used = (Convert.ToDouble(Return["Size"]) - Convert.ToDouble(Return["FreeSpace"])) / GB;
                        //硬盘的总空间
                        total = Convert.ToDouble(Return["Size"]) / GB;
                    }
                   
                }
            }
            catch (Exception ee)
            {
                log.Error(ee.StackTrace);
                log.Error(ee.Message);
            }
            dic.Add("Name",name.ToString());
            dic.Add("Size", total.ToString("F1"));
            dic.Add("Used", used.ToString("F1"));
            dic.Add("FreeSpace", free.ToString("F1"));

            return dic;
        }

二、获得远程计算机的其他数据

//网络        Query = new System.Management.ObjectQuery("Select IODataBytesPerSec from Win32_PerfRawData_PerfProc_Process");

//CPU        Query = new System.Management.ObjectQuery("select LoadPercentage from Win32_Processor ");

//总内存     Query = new System.Management.ObjectQuery("Select TotalVisibleMemorySize from Win32_OperatingSystem");

//可用内存  Query = new System.Management.ObjectQuery("Select FreePhysicalMemory from Win32_OperatingSystem");
