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;        }
