C#实现Check Password和锁定输错密码锁定账户功能

银行卡大家都使用，在密码输错超过限制次数之后，就容易被锁死，智能到银行柜台才能解锁，那么这一功能如果实现的呢，今天小编通过实例代码给大家详细讲解，一起跟随小编看看吧。

c#实现的check password，并根据输错密码的次数分情况锁定账户：如果输入错误3次，登录账户锁定5分钟并提示x点x分后重试登录。如果5分钟后再次输入，累计输入错误密码累计达到5次。则账户会被永久锁定，需联系系统管理员进行把数据库中的输入错误的次数（errorcount）进行清零解锁才能登陆。实现代码如下：

 public class userinfo1
 {
  public string error_count { get; set; }
  public string error_time { get; set; }
 } 


 public executionresult checkaccountpwd(string account, string password)
  {
   executionresult execres;
   execres = new executionresult();

   string[] strs = account.split(new string[] { "\\" }, stringsplitoptions.removeemptyentries);
   if (strs.length < 2)
   {
    execres.status = false;
    execres.message = "无效的账号。";
   }
   else
   {
    userinfo1 info1 = null;
    execres = calleepmethod.execute(dbname, "sdem2131", "getuserinfo", strs[1].tolower());
    if (execres.status && execres.anything != null)
    {
     info1 = jsonconvert.deserializeobject<userinfo1>(execres.anything.tostring());
     if (info1 != null)
     {
      int errcount = convert.toint32(info1.error_count);
      datetime errtime = convert.todatetime(info1.error_time);
      if (errcount != 5)
      {
       //int errorcount
       datetime dt0 = datetime.now;
       datetime dt1 = errtime.addminutes(5);
       double s = (dt1 - dt0).totalseconds;
       if (errcount == 3 && s > 0)
       {
        execres.status = false;
        execres.message = "密码连续输入错误3次，请于 " + errtime.addminutes(+5).tostring("yyyy-mm-dd hh:mm:ss") + " 之后重试，thanks!";
       }
       else
       {
        if (checkfromldap(strs[1], password, strs[0]))
        {
         cpu.models.userinfo userinfo = checkuser(strs[1]);
         if (userinfo == null)
         {
          execres.status = false;
          execres.message = "您没有权限操作此系统！";
         }
         else
         {
          execres.status = true;
          execres.anything = userinfo;
          //error count 清0
          calleepmethod.execute(dbname, "sdem2131", "updateuserloginerror", strs[1].tolower() + ","+"0" + "," + datetime.now.tostring("yyyy/mm/dd hh:mm:ss"));
          
         }
        }
        else
        {
         execres.status = false;
         // 次数+1
         if (errcount + 1 > 1)
          execres.message = "密码连续输入错误" + (errcount+1).tostring() + "次。密码连续输错5次将锁定！";
         else
          execres.message = "密码输入错误!";
         dt0 = datetime.now;
         calleepmethod.execute(dbname, "sdem2131", "updateuserloginerror", strs[1].tolower() + "," + (errcount + 1).tostring()+"," + datetime.now.tostring("yyyy/mm/dd hh:mm:ss"));
         if (errcount + 1 == 3)
          execres.message = "密码连续输入错误" + (errcount + 1).tostring() + "次，请于 " + dt0.addminutes(5).tostring("yyyy-mm-dd hh:mm:ss") + " 之后重试，thanks!";
         if (errcount + 1 == 5)
          execres.message = "账号密码连续输入错误5次，已锁定!请联系管理员解锁，thanks!";
        }
       }
      }
      else
      {
       execres.status = false;
       execres.message = "账号密码连续输入错误5次，已锁定!请联系管理员解锁，thanks!";
      }
     }
     else
     {
      execres.status = false;
      execres.message = "找不到此账号，请重新输入!";
     }
    }
    else
    {
     execres.status = false;
     execres.message = "找不到此账号，请重新输入!";
    }
   }
   return execres;
  }

根据登录不同的网域进行form验证

 private bool checkfromldap(string ntid, string ntpwd, string domain)//根据登录的不同网域进行form验证
  {
   bool result = false;
   string struser;
   try
   {
    struser = domain + "\\" + ntid;
    if (domain.tolower().equals("gi"))
     domain = "gi.compal.com";
    else if (domain.tolower().equals("cqc_cci"))
     domain = "10.140.1.1";
    else if (domain.tolower().equals("vn"))
     domain = "10.144.2.101";
    else if (domain.tolower().equals("njp_cci"))
     domain = "10.128.50.1";
    else
     domain = "compal.com";
    directoryentry entry = new directoryentry("ldap://" + domain, struser, ntpwd);
    using (directorysearcher searcher = new directorysearcher(entry))
    {
     searcher.filter = string.format("(&(objectclass=user)(samaccountname={0}))", ntid);
     searchresult sr = searcher.findone();
     using (searchresultcollection results = searcher.findall())
     {
      if (results.count > 0)
      {
       //if (results[0].properties.contains("employeeid"))
       // empid = results[0].properties["employeeid"][0].tostring();
       //else
       // empid = results[0].properties["extensionattribute3"][0].tostring();
       result = true;
      }
     }
    }
   }
   catch (exception ex)
   {
    //loghelper.error(ex.message);
   }

   return result;
  }

根据不同的用户登录进行权限管理

public bool checkpermission(string controllername, string actionname,string plant, string userid)
  {
   bool result = false;
   //if (actionname.startswith("_"))
   // actionname = actionname.substring(1);
   userinfo userinfo = checkuser(userid);
   if (userinfo!=null)
   {
    if (controllername == "home")
     result = true;
    else if (userinfo.permissions.contains(controllername))
    {
     if (!string.isnullorempty(plant))
     {
      if (userinfo.plantcode.tolower() == plant.tolower() || userinfo.plantcode == "all")
       result = true;
     }
     else
      result = true;
    }
   }
   return result;
  }
