　　以下是引用片段 int result = user GetBackPassword(LoginName Text Trim() Question Text Trim() Answer Text Trim() Email Text); if (result == ) Message Text = 您的密码已发送请到邮箱查收 ; //user ChangePassword( else Message Text = 您的输入信息有误！ ; public int GetBackPassword(string userName string question string answer string email) object m_DBNull = Convert DBNull; //获得新的随机密码 string newPassword = MakePassword( ); //定义存储过程参数 SqlParameter[] para = new SqlParameter( @userName userName) new SqlParameter( @question question) new SqlParameter( @answer answer) new SqlParameter( @newPassword newPassword) new SqlParameter( @result SqlDbType Int ParameterDirection Output true DataRowVersion Default m_DBNull) ; //执行存储过程 try DAL SQLHelper ExecuteNonQuery(DAL SQLHelper CONN_STRING CommandType StoredProcedure GetBackPwd para); catch throw new Exception( 邮件无法发送！ ); //获得输出参数的值 int result = Convert ToInt (para[ ] Value); //如果密码保护资料填写正确 if (result == ) //从nfig获取发信人地址邮件标题邮件用户名和密码以及SmtpServer string sender = System Configuration ConfigurationSettings AppSettings[ mainSender ]; string title = System Configuration ConfigurationSettings AppSettings[ mailTitle ]; string mailUser = System Configuration ConfigurationSettings AppSettings[ mailUser ]; string mailPwd = System Configuration ConfigurationSettings AppSettings[ mailPwd ]; string smtpServer = System Configuration ConfigurationSettings AppSettings[ mailSmtpServer ]; //发信 try Mail CDOsendmail(sender email title 您在eshop的密码已找回新密码为 +newPassword mailUser mailPwd smtpServer); catch(Exception ex) throw new Exception(ex Message); return result; //随机生成密码 private static string MakePassword(int pwdLength) //声明要返回的字符串 string tmpstr = ; //密码中包含的字符数组 string pwdchars= abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ ; //数组索引随机数 int iRandNum; //随机数生成器 Random rnd = new Random(); for(int i= ;i<pwdLength;i++) //Random类的Next方法生成一个指定范围的随机数 iRandNum = rnd Next(pwdchars Length); //tmpstr随机添加一个字符 tmpstr += pwdchars[iRandNum]; return tmpstr; ALTER PROCEDURE GetBackPwd @question nvarchar( ) @answer nvarchar( ) @userName nvarchar( ) @newPassword nvarchar( ) @result int output AS if exists (SELECT * FROM USERINFO WHERE USERNAME=@USERNAME AND QUESTION=@QUESTION AND ANSWER=@ANSWER) BEGIN SET @RESULT = UPDATE USERINFO SET USERPWD = @newPassword WHERE userName = @userName END ELSE BEGIN SET @RESULT = END GO SET QUOTED_IDENTIFIER OFF GO SET ANSI_NULLS ON GO <add key= mailUser value= /> <add key= mailPwd value= /> <add key= mailSmtpServer value= /> <add key= mailSender value= /> <add key= mailTitle value= />
