己经 using System.ManagementClass,调试时还是出现错误 3 找不到类型或命名空间名称“ManagementClass”(是否缺少 using 指令或程序集引用?) 这是为什么呀?WINFORM程序标准引用是不包含System.Management的，要手工添加引用

ManagementClass 无法获取磁盘分区

WINFORM程序，代码如下：public static DataTable testDisk() { DataTable dt = new DataTable(); dt.Columns.Add("path"); dt.Columns.Add("totalSpace"); dt.Columns.Add("freeSpace"); dt.Columns.Add("freePencent"); ManagementClass diskClass = new ManagementClass("Win32_LogicalDisk"); ManagementObjectCollection disks = diskClass.GetInstances(); try { foreach (ManagementObject disk in disks) { DataRow dr; UInt64 k = 1024; dr = dt.NewRow(); dr[0] = disk["Name"].ToString(); dr[1] = (UInt64)(disk["FreeSpace"]) / k / k;//转为MB dr[2] = (UInt64)(disk["Size"]) / k / k;//转为MB int free = int.Parse((UInt64.Parse(dr[1].ToString())).ToString()); int total = int.Parse((UInt64.Parse(dr[2].ToString())).ToString()); dr[3] = (((free * 1.0000) / (total * 1.0000)) * 100).ToString("f2") + "%"; dr[1] += "MB"; dr[2] += "MB"; dt.Rows.Add(dr); }//MessageBox.Show(freeSpace.ToString()); return dt; } catch (Exception ex) { return dt; } }在WIN7 SERVER2008中获取分区都正常，但是在2012中获取分区返回为空，尝试使用管理员身份运行也不行，求大神帮忙看下是什么地方的问题，是不是SERVER2012中不支持Win32_LogicalDisk，需要换成什么补充，测试是在VM14.1.3的虚拟机中测试的，无法获取温度功耗传感器参数是可以理解的，但是无法获取磁盘分区信息就很奇怪了。编译环境VS2017，.NET4.7

  C几种读取MAC地址的方法

  以下是收集的几种C程序读取MAC地址的方法，示例中是读取所有网卡的MAC地址，如果仅需要读取其中一个，稍作修改即可。1 通过IPConfig命令读取MAC地址///<summary>/// 根据截取ipconfig /all命令的输出流获取网卡Mac///</summary>///<returns></returns>publicstatic List<string> GetMacByIPConfig(){List<string> macs =new List<string>();ProcessStartInfo startInfo = new ProcessStartInfo("ipconfig", "/all");startInfo.UseShellExecute = false;startInfo.RedirectStandardInput = true;startInfo.RedirectStandardOutput = true;startInfo.RedirectStandardError = true;startInfo.CreateNoWindow = true;Process p = Process.Start(startInfo);//截取输出流StreamReader reader = p.StandardOutput;string line = reader.ReadLine();while (!reader.EndOfStream){if (!string.IsNullOrEmpty(line)){line = line.Trim();if (line.StartsWith("Physical Address")){macs.Add(line);}}line = reader.ReadLine();}//等待程序执行完退出进程p.WaitForExit();p.Close();reader.Close();return macs;}2 通过WMI读取MAC地址1）该方法依赖WMI的系统服务，该服务一般不会被关闭；但如果系统服务缺失或者出现问题，该方法无法取得MAC地址。///<summary>/// 通过WMI读取系统信息里的网卡MAC///</summary>///<returns></returns>publicstatic List<string> GetMacByWMI(){List<string> macs =new List<string>();try{string mac ="";ManagementClass mc =new ManagementClass("Win32_NetworkAdapterConfiguration");ManagementObjectCollection moc = mc.GetInstances();foreach (ManagementObject mo in moc){if ((bool)mo["IPEnabled"]){mac = mo["MacAddress"].ToString();macs.Add(mac);}}moc =null;mc =null;}catch{}return macs;}3 通过NetworkInterface读取MAC地址1）如果当前的网卡是禁用状态（硬件处于硬关闭状态），取不到该网卡的MAC地址，（您可以通过禁用网卡进行试验）。2）如果当前启用了多个网卡，最先返回的地址是最近启用的网络连接的信息//返回描述本地计算机上的网络接口的对象(网络接口也称为网络适配器)。publicstatic NetworkInterface[] NetCardInfo(){return NetworkInterface.GetAllNetworkInterfaces();}///<summary>/// 通过NetworkInterface读取网卡Mac///</summary>///<returns></returns>publicstatic List<string> GetMacByNetworkInterface(){List<string> macs =new List<string>();NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();foreach (NetworkInterface ni in interfaces){macs.Add(ni.GetPhysicalAddress().ToString());}return macs;}4 通过SendARP读取MAC地址///<summary>/// 通过SendARP获取网卡Mac/// 网络被禁用或未接入网络（如没插网线）时此方法失灵///</summary>///<param name="remoteIP"></param>///<returns></returns>publicstaticstring GetMacBySendARP(string remoteIP){StringBuilder macAddress =new StringBuilder();try{Int32 remote = inet_addr(remoteIP);Int64 macInfo =new Int64();Int32 length =6;SendARP(remote, 0, ref macInfo, ref length);string temp = Convert.ToString(macInfo, 16).PadLeft(12, &39;0&39;).ToUpper();int x =12;for (int i =0; i <6; i++){if (i ==5){macAddress.Append(temp.Substring(x -2, 2));}else{macAddress.Append(temp.Substring(x -2, 2) +"-");}x -=2;}return macAddress.ToString();}catch{return macAddress.ToString();}}[DllImport("Iphlpapi.dll")]privatestaticexternint SendARP(Int32 dest, Int32 host, ref Int64 mac, ref Int32 length);[DllImport("Ws2_32.dll")]privatestaticextern Int32 inet_addr(string ip);5 从注册表读取MAC地址常规用户可通过读取注册表项Windows Genuine Advantage获取到物理网卡地址。1）如果注册表项被修改，则无法取得该MAC地址HKEY_LOCAL_MACHINE&92;Software&92;Microsoft&92;Windows Genuine Advantage
