奇怪的工作，制作的是一款办公应用软件，领导却要求我统计用户计算机的物理信息，什么CPU的型号、核心数，什么内存信息等各种乱七八糟的用户信息。我想问，现在用户的信息就这么没有隐私性了么？想获取就获取传递到后台……无奈我只是民工，还是老老实实做了。然后查阅了一些资料，主要用到了System.Management命名空间下的信息（System.Management 命名空间 | Microsoft Docs）。
1、引用
在查询计算机硬件或者操作系统的信息时，使用ManagementObjectSearcher类或者ManagementClass类，其在在System.Management命名空间下，需要添加对System.Management的引用。
在日常的编程中，我们可以通过Environment获得一些简单的系统信息，如获得操作系统登录用户名：Environment.UserName。 但更多、复杂的信息并不能获得。
2、用法
下面两部分代码分别演示获取操作系统信息：
1、使用ManagementObjectSearcher类
ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");//注意查询的类型 from * ManagementObjectSearcher searcher =new ManagementObjectSearcher(query);//也可以直接将查询字符串写入这个构造函数中 ManagementObjectCollection queryCollection = searcher.Get(); foreach (ManagementObject m in queryCollection) { Console.WriteLine("Computer Name : {0}", m["csname"]); Console.WriteLine("Windows Directory : {0}", m["WindowsDirectory"]); Console.WriteLine("Operating System: {0}", m["Caption"]); Console.WriteLine("Version: {0}", m["Version"]); Console.WriteLine("Manufacturer : {0}", m["Manufacturer"]); }
2、使用ManagementClass类
ManagementClass mc = new ManagementClass("Win32_OperatingSystem");//填入需要查询的类型 ManagementObjectCollection queryCollection = mc.GetInstances(); foreach (ManagementObject m in queryCollection) { Console.WriteLine("Computer Name : {0}", m["csname"]); Console.WriteLine("Windows Directory : {0}", m["WindowsDirectory"]); Console.WriteLine("Operating System: {0}", m["Caption"]); Console.WriteLine("Version: {0}", m["Version"]); Console.WriteLine("Manufacturer : {0}", m["Manufacturer"]); }
如果不知道要获取的属性名称，可以循环遍历打印出来（注意获取值的方式有两种）。
ManagementClass mc = new ManagementClass("Win32_OperatingSystem");//填入需要查询的类型 ManagementObjectCollection moc = mc.GetInstances(); foreach (ManagementObject mo in moc) { foreach (PropertyData pd in mo.Properties) { if (mo[pd.Name] != null && mo[pd.Name].ToString() != "") { Console.WriteLine(string.Format("{0}:{1}", pd.Name, mo.GetPropertyValue(pd.Name))); } } }
3、示例
以生成注册码为例，注册码使用CPU的序列号和C盘的序列号为基准：
/// <summary> /// 获取CPU序列号 /// </summary> /// <returns></returns> private string GetCpuNum() { ManagementClass mc = new ManagementClass("Win32_Processor");//填入需要查询的类型 ManagementObjectCollection queryCollection = mc.GetInstances(); foreach (ManagementObject m in queryCollection) { return m.GetPropertyValue("Processorid").ToString(); } return string.Empty; } /// <summary> /// 取得设备硬盘的卷标号 /// </summary> /// <returns></returns> private Dictionary<string,string> GetDiskVolumeSerialNumber() { Dictionary<string, string> keyValuePairs = new Dictionary<string, string>(); ManagementClass mc = new ManagementClass("Win32_LogicalDisk");//填入需要查询的类型 ManagementObjectCollection queryCollection = mc.GetInstances(); foreach (ManagementObject mo in queryCollection) { keyValuePairs.Add(mo.GetPropertyValue("DeviceID").ToString().Trim(':'), mo.GetPropertyValue("VolumeSerialNumber").ToString()); } return keyValuePairs; } ///<summary> ///生成注册码 ///</summary> ///<returns></returns> public string GetRegCode() { int[] intCode = new int[127];//存储密钥 int[] intNumber = new int[25];//存机器码的Ascii值 char[] Charcode = new char[25];//存储机器码字 //初始化127位数组 for (int i = 1; i < intCode.Length; i++) { intCode[i] = i % 9; } string cpuNum = GetCpuNum(); string diskSerialNumber = GetDiskVolumeSerialNumber()["C"]; string strNum = cpuNum + diskSerialNumber;//生成机器码 string MNum = strNum.Substring(0, 24);//从生成的字符串中取出前24个字符做为机器码 for (int i = 1; i < Charcode.Length; i++)//把机器码存入数组中 { Charcode[i] = Convert.ToChar(MNum.Substring(i - 1, 1)); } for (int j = 1; j < intNumber.Length; j++)//把字符的ASCII值存入一个整数组中。 { intNumber[j] = intCode[Convert.ToInt32(Charcode[j])] + Convert.ToInt32(Charcode[j]); } string strAsciiName = "";//用于存储注册码 for (int j = 1; j < intNumber.Length; j++) { if (intNumber[j] >= 48 && intNumber[j] <= 57)//判断字符ASCII值是否0－9之间 { strAsciiName += Convert.ToChar(intNumber[j]).ToString(); } else if (intNumber[j] >= 65 && intNumber[j] <= 90)//判断字符ASCII值是否A－Z之间 { strAsciiName += Convert.ToChar(intNumber[j]).ToString(); } else if (intNumber[j] >= 97 && intNumber[j] <= 122)//判断字符ASCII值是否a－z之间 { strAsciiName += Convert.ToChar(intNumber[j]).ToString(); } else//判断字符ASCII值不在以上范围内 { if (intNumber[j] > 122)//判断字符ASCII值是否大于z { strAsciiName += Convert.ToChar(intNumber[j] - 10).ToString(); } else { strAsciiName += Convert.ToChar(intNumber[j] - 9).ToString(); } } } return strAsciiName;//返回注册码 }
4、常用的Key
ObjectQuery和ManagementClass都需要输入Key值，以明确需要获取什么类型的数据。其常用的Key值如下：
