C#实现的Check Password和锁定输错密码锁定账户

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c#教程解锁才能登陆。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 errorCountDateTime 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0CallEEPMethod.Execute(dbName, "sDEM2131", "UpdateUserLoginError", strs[1].ToLower() + ","+"0" + "," + DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss"));}}else{execRes.Status = false;// 次数+1if (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！";elseexecRes.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";elsedomain = "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;}elseresult = true;}}return result;}
