获取windows 操作系统下的硬件或操作系统信息等

　　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
}
