C#实现生成mac地址与IP地址注册码的两种方法_c#

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)

      if (cpuid != "")
      {
        md5 md = new md5cryptoserviceprovider();

        return (softname + "c" + cpuid);
      }
      if (biosserialnumber != "")
      {

        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 = "";

        {
          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();
}
