C#中使用ManagementClass获取本机信息 C# 硬件码获取电脑配置信息

C#提供 ManagementClass来对机器的信息进行管理，可以通过设定不同的管理类来获得机器的基本信息。下面给出了一些基本的信息的获取方法，包括获取CPU数目，cpu频率，内存大小，硬盘大小。

private void GetLocalInfo()
        {
            string cpuCount;
            string hdSize;
            string memorysize;

            //得到CPU信息
            ManagementClass mcpu = new ManagementClass("Win32_Processor");
            ManagementObjectCollection mncpu = mcpu.GetInstances();
            cpuCount = mncpu.Count.ToString();
            string[] cpuHz = new string[mncpu.Count];
            int count = 0;
            ManagementObjectSearcher MySearcher = new ManagementObjectSearcher("SELECT * FROM Win32_Processor");
            foreach (ManagementObject MyObject in MySearcher.Get())
            {
                cpuHz[count] = MyObject.Properties["CurrentClockSpeed"].Value.ToString();
                count++;
            }
            mncpu.Dispose();
            mcpu.Dispose();

            //得到硬盘信息
            ManagementClass mcHD = new ManagementClass("Win32_DiskDrive");
            ManagementObjectCollection moHD = mcHD.GetInstances();

            foreach (ManagementObject tempob in moHD)
            {
                hdSize = tempob.Properties["Size"].Value.ToString();
            }
            moHD.Dispose();
            mcHD.Dispose();

            //得到内存信息
            ManagementClass mcMemory = new ManagementClass("Win32_OperatingSystem");
            ManagementObjectCollection mocMemory = mcMemory.GetInstances();

            double sizeall = 0;
            foreach (ManagementObject mo in mocMemory)
            {
                if (mo.Properties["TotalVisibleMemorySize"].Value != null)
                {
                    sizeall += double.Parse(mo.Properties["TotalVisibleMemorySize"].Value.ToString());
                }
            }
            memorysize = sizeall.ToString();
            mocMemory.Dispose();
            mcMemory.Dispose();

}
//获取mac地址

public static ArrayList GetMacAddress()
        {
            ManagementClass class1 = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection collection1 = class1.GetInstances();
            ArrayList list1 = new ArrayList();
            using (ManagementObjectCollection.ManagementObjectEnumerator enumerator1 = collection1.GetEnumerator())
            {
                while (enumerator1.MoveNext())
                {
                    ManagementObject obj1 = enumerator1.get_Current();
                    if ((bool) obj1.get_Item("IPEnabled"))
                    {
                        list1.Add(obj1.get_Item("MacAddress").ToString().Replace(":", ""));
                    }
                    obj1.Dispose();
                }
            }
            return list1;
        }

//ping网络状态

[DllImport("wininet.dll")]
        private static extern bool InternetGetConnectedState(int Description, int ReservedValue);
        public static bool IsConnectedToInternet()
        {
            int num1 = 0;
            return InternetGetConnectedState(num1, 0);
        }

using System;

using System.Collections;

using System.Diagnostics;

using System.Management;

using System.Net;

using System.DirectoryServices;

using System.Runtime.InteropServices;

using System.Text.RegularExpressions;

获得本机的MAC地址

public static string GetLocalMac()

{

string strMac = string.Empty;

ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");

ManagementObjectCollection moc = mc.GetInstances();

foreach(ManagementObject mo in moc)

{

if ((bool)mo["IPEnabled"] == true)

strMac += mo["MacAddress"].ToString() ;

}

return strMac.ToUpper();

}

获得远程计算机的MAC地址

方法一：使用API，利用ARP协议，只能获得同网段计算机的MAC

[DllImport("Iphlpapi.dll")]

private static extern int SendARP(Int32 dest,Int32 host,ref Int64 mac,ref Int32 length);

[DllImport("Ws2_32.dll")]

private static extern Int32 inet_addr(string ip);

public static string GetRemoteMac(string clientIP)

{

string ip = clientIP;

if ( ip == "127.0.0.1")

ip = GetLocalIP()[0];

Int32 ldest=inet_addr(ip);

Int64 macinfo=new Int64();

Int32 len=6;

try

{

SendARP(ldest,0,ref macinfo,ref len);

}

catch

{

return "";

}

string originalMACAddress = Convert.ToString(macinfo,16);

if (originalMACAddress.Length<12)

{

originalMACAddress = originalMACAddress.PadLeft(12,'0');

}

string macAddress;

if(originalMACAddress!="0000" && originalMACAddress.Length==12)

{

string mac1,mac2,mac3,mac4,mac5,mac6;

mac1=originalMACAddress.Substring(10,2);

mac2=originalMACAddress.Substring(8,2);

mac3=originalMACAddress.Substring(6,2);

mac4=originalMACAddress.Substring(4,2);

mac5=originalMACAddress.Substring(2,2);

mac6=originalMACAddress.Substring(0,2);

macAddress=mac1+"-"+mac2+"-"+mac3+"-"+mac4+"-"+mac5+"-"+mac6;

}

else

{

macAddress="";

}

return macAddress.ToUpper();

}

方法二：使用windows的命令nbtstat

public static string GetRemoteMacByNetBIOS(string clientIP)

{

string ip = clientIP;

if ( ip == "127.0.0.1")

ip = GetLocalIP()[0];

string dirResults="";

ProcessStartInfo psi = new ProcessStartInfo();

Process proc = new Process();

psi.FileName = "nbtstat.exe";

//psi.RedirectStandardInput = false;

psi.RedirectStandardOutput = true;psi.RedirectStandardError=true;

psi.Arguments = "-A " + ip;

psi.UseShellExecute = false;

proc = Process.Start(psi);

dirResults = proc.StandardOutput.ReadToEnd();

string error = proc.StandardError.ReadToEnd();

proc.WaitForExit();

dirResults=dirResults.Replace("\r","").Replace("\n","").Replace("\t","");

Regex reg=new Regex("Mac[ ]{0,}Address[ ]{0,}=[ ]{0,}(?((.)*?))__MAC",RegexOptions.IgnoreCase|RegexOptions.Compiled);

Match mc=reg.Match(dirResults+"__MAC");

if(mc.Success)

{

return mc.Groups["key"].Value.ToUpper();

}

else

{

return "";

}

使用此方法需要足够的操作系统的权限。在Web中,可以将ASP.net用户加入管理员组。

对于上面两个地方都用到的GetLocalIP是一个获取本机IP的方法：

public static string[] GetLocalIP()

{

string hostName = Dns.GetHostName();

IPHostEntry ipEntry=Dns.GetHostByName(hostName);

IPAddress[] arr=ipEntry.AddressList;

string[] result = new string[arr.Length];

for(int i=0;i { ;i++)>

result[i] = arr[i].ToString();

}

return result;

} ;i++)>

获得局域网内计算机的列表

方法一：使用逐个IP地址扫描的方式

利用多线程来对每个IP逐个扫描。

ComputerAddressInfo cai = new ComputerAddressInfo("192.168.1",42,53);

Thread thScan = new Thread(new ThreadStart(cai.ScanComputers));

thScan.Start();

//...

public class ComputerAddressInfo

{

private int startIP = 0;

private int endIP = 0;

private string ipPrefix = "";

private ArrayList computerList = null;

public ComputerAddressInfo(string ipPrefix,int startIP,int endIP)

{

this.startIP = startIP;

this.endIP = endIP;

this.ipPrefix = ipPrefix;

computerList = new ArrayList();

}

public void ScanComputers()

{

for(int i=startIP;i<=endIP;i++)

{

string scanIP = ipPrefix +"."+i.ToString();

IPAddress myScanIP = IPAddress.Parse(scanIP);

IPHostEntry myScanHost = null;

string[] arr = new string[2];

try

{

myScanHost = Dns.GetHostByAddress(myScanIP);

}

catch

{

continue;

}

if (myScanHost != null)

{

arr[0] = myScanHost.HostName;

arr[1] = scanIP;

computerList.Add(arr);

}

此方法速度比较慢。

方法二：使用Active Directory

public static ArrayList GetComputerList()

{

ArrayList list = new ArrayList();

//or use "WinNT://your_domain_name"

DirectoryEntry root = new DirectoryEntry("WinNT:");

DirectoryEntries domains = root.Children;

domains.SchemaFilter.Add("domain");

foreach (DirectoryEntry domain in domains)

{

DirectoryEntries computers = domain.Children;

computers.SchemaFilter.Add("computer");

foreach (DirectoryEntry computer in computers)

{

object[] arr = new string[3];

IPHostEntry iphe = null;

try

{

iphe = Dns.GetHostByName(computer.Name);

}

catch

{

continue;

}

arr[0] = domain.Name;

arr[1] = computer.Name;

if ( iphe != null && iphe.AddressList.Length >0 )

{

for ( int i=0;i arr[2] += iphe.AddressList[i].ToString()+","; ;i++)>

arr[2] = arr[2].ToString().Remove(arr[2].ToString().Length-1,1);

}

else

arr[2] = "";

list.Add(arr);

}

return list;

}

此方法速度也比较慢。

后记

上面两个获得局域网内的计算机列表的方法都很费时，目前还没有找到更好的办法。

需要强调的是客户机器的硬件信息获取方式是有很多种选择的. 这里我们选择最放心的两个硬件: CUP的序列号和硬盘的卷标号. 好了, 下面您就可以一步一步制作一款软件注册机了.

步骤一: 获得CUP序列号和硬盘序列号的实现代码如下:

 strCpu;
        }

).ToString();
        }

步骤二: 收集硬件信息生成机器码, 代码如下:

)];
            }
        }

步骤三: 使用机器码生成软件注册码, 代码如下:

); }
        }

步骤四: 用户输入注册码注册软件, 演示代码如下:

); }

        }

        private static string CpuID()
        {
            string cpuID = "";

        private static string MacAddress()
        {
            string macAddress = "";

return macAddress;
}

        private static string DiskID()
        {
            string diskID = "";

        private static string SystemType()
        {
            string systemType = "";

return systemType;
}

        private static string TotalPhysicalMemory()
        {
            string totalPhysicalMemory = "";

            {
                mc = new ManagementClass("Win32_ComputerSystem");
                moc = mc.GetInstances();
                foreach (ManagementObject mo in moc)
                {
