本文实例讲述了C#实现生成mac地址与IP地址注册码的两种方法，分享给大家供大家参考之用。具体方法如下：

方法一：

using System;using System.Management;using System.Security.Cryptography;using System.IO;using System.Collections.Generic;using System.Text;namespace xingming_reg{ class Program { static void Main(string[] args) { bool sucsess = false; string computerbit = ""; regmutou reg = new regmutou(); computerbit = reg.getcomputerbit("X"); sucsess = reg.regmutousoft(computerbit, "xinmin", "xinmin.usr"); Console.WriteLine(sucsess); Console.ReadLine(); } } internal class regmutou { // Methods public string GetBIOSSerialNumber() { try { ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * From Win32_BIOS"); string str = ""; foreach (ManagementObject obj2 in searcher.Get()) { str = obj2["SerialNumber"].ToString().Trim(); } return str; } catch { return ""; } } public string getcomputerbit(string softname) { string cpuID = this.GetCpuID(); string bIOSSerialNumber = this.GetBIOSSerialNumber(); string hardDiskSerialNumber = this.GetHardDiskSerialNumber(); string netCardMACAddress = this.GetNetCardMACAddress(); if (cpuID != "") { MD5 md = new MD5CryptoServiceProvider(); cpuID = BitConverter.ToString(md.ComputeHash(Encoding.Default.GetBytes(cpuID))).Replace("-", "").ToUpper().Substring(8, 0x10); return (softname + "C" + cpuID); } if (bIOSSerialNumber != "") { MD5 md2 = new MD5CryptoServiceProvider(); bIOSSerialNumber = BitConverter.ToString(md2.ComputeHash(Encoding.Default.GetBytes(bIOSSerialNumber))).Replace("-", "").ToUpper().Substring(8, 0x10); return (softname + "B" + bIOSSerialNumber); } if (hardDiskSerialNumber != "") { MD5 md3 = new MD5CryptoServiceProvider(); hardDiskSerialNumber = BitConverter.ToString(md3.ComputeHash(Encoding.Default.GetBytes(hardDiskSerialNumber))).Replace("-", "").ToUpper().Substring(8, 0x10); return (softname + "H" + hardDiskSerialNumber); } if (netCardMACAddress != "") { MD5 md4 = new MD5CryptoServiceProvider(); netCardMACAddress = BitConverter.ToString(md4.ComputeHash(Encoding.Default.GetBytes(netCardMACAddress))).Replace("-", "").ToUpper().Substring(8, 0x10); return (softname + "N" + netCardMACAddress); } return (softname + "WF53A419DB238BBAD"); } public string GetCpuID() { try { ManagementObjectCollection instances = new ManagementClass("Win32_Processor").GetInstances(); string str = null; foreach (ManagementObject obj2 in instances) { str = obj2.Properties["ProcessorId"].Value.ToString(); break; } return str; } catch { return ""; } } public string GetHardDiskSerialNumber() { try { ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia"); string str = ""; foreach (ManagementObject obj2 in searcher.Get()) { str = obj2["SerialNumber"].ToString().Trim(); break; } return str; } catch { return ""; } } public string GetNetCardMACAddress() { try { ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapter WHERE ((MACAddress Is Not NULL) AND (Manufacturer <> 'Microsoft'))"); string str = ""; foreach (ManagementObject obj2 in searcher.Get()) { str = obj2["MACAddress"].ToString().Trim(); } return str; } catch { return ""; } } public bool regmutousoft(string computerbit, string softname, string filename) { bool flag = true; string str = ""; SHA1 sha = new SHA1CryptoServiceProvider(); str = BitConverter.ToString(sha.ComputeHash(Encoding.Default.GetBytes(softname))).Replace("-", "").ToUpper(); //if (!File.Exists(filename)) //{ // flag = false; // Stream stream = File.Open(filename, FileMode.OpenOrCreate); // StreamWriter writer = new StreamWriter(stream); // writer.WriteLine(computerbit); // writer.Close(); // stream.Close(); // return flag; //} //Stream stream2 = File.Open(filename, FileMode.Open); //StreamReader reader = new StreamReader(stream2); //string str2 = ""; string str3 = computerbit; //while ((str2 = reader.ReadLine()) != null) //{ // str3 = str2; //} //reader.Close(); //stream2.Close(); //if (str3.Length != 0x18) //{ // //return false; //} SHA1 sha2 = new SHA1CryptoServiceProvider(); string str4 = BitConverter.ToString(sha2.ComputeHash(Encoding.Default.GetBytes(computerbit))).Replace("-", "").ToUpper(); string str5 = ""; for (int i = 0; i < str4.Length; i++) { if ((i % 2) == 1) { str5 = str5 + str4[i]; } } string str6 = ""; for (int j = 0; j < str.Length; j++) { if ((j % 2) == 0) { str6 = str6 + str[j]; } } int[] numArray = new int[20]; for (int k = 0; k < 20; k++) { numArray[k] = str6[k] + str5[k]; numArray[k] = numArray[k] % 0x24; } string str7 = ""; for (int m = 0; m < 20; m++) { if ((m > 0) && ((m % 4) == 0)) { str7 = str7 + "-"; } str7 = str7 + "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"[numArray[m]]; } if (str3 == str7) { flag = true; } Console.WriteLine("机器码:" + str3); Console.WriteLine("注册码:"+str7); return flag; } }}

方法二：

using System.Management;//Win32_NetworkAdapterConfiguration是WMI数据库中用来存放网络设备的信息表ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled='TRUE'");//ManagementObjectCollection对象用来存放查询结果ManagementObjectCollection queryCollection = query.Get();foreach (ManagementObject mo in queryCollection){ Console.WriteLine("Network Card:{0}", mo["Description"]); Console.WriteLine("MAC Address:{0}", mo["MACAddress"]); //addresses, subnets和 defaultgateways 值都是可以包含多个值得数组. //为了适应这种情况,为了适应这种情况,用户必须把结果分配到一个字符串数组, //并再一次用foreach语句通过该字符串数组 string[] addresses = (string[])mo["IPAddress"]; string[] subnets = (string[])mo["IPSubnet"]; string[] defaultgateways = (string[])mo["DefaultIPGateway"]; //任何一个接口都可能有多个IP地址 foreach (string ipaddress in addresses) { Console.WriteLine("IP Address:{0}", ipaddress); } foreach (string subnet in subnets) { Console.WriteLine("Subnet Mask:{0}", subnet); } foreach (string defaultgateway in defaultgateways) { Console.WriteLine("Gateway:{0}", defaultgateway); } Console.WriteLine();}
