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;
  }
