2021年A C经验交流C编程忘记___功能的实现方法

1、A C经验交流C编程忘记 _功能的实现方法 经验交流；C#编程忘记 _功能的实现方法 本文将给出通过C#编程来实现 忘记 _ 功能的方法和代码，大家可以参照本文的思路自己写出这个功能代码 以下是引用片段： int result = user.GetBackPassword(LoginName.Text.Trim(), Question.Text.Trim(), Answer.Text.Trim(), E _il.Text); if (result = 1) Message.Text = 您的 _已发送，请到邮箱查收; /user.ChangePassword( else Message.Tex

2、t = 您的输入信息有误！; public int GetBackPassword(string userName, string question, string answer, string e _il) object m_DBNull = Convert.DBNull; /获得新的随机 _ string newPassword = MakePassword(6); /定义存储过程参数 SqlParameter para = new SqlParameter(userName, userName), new SqlParameter(question, question), new Sql

3、Parameter(answer, answer), new SqlParameter(newPassword, newPassword), new SqlParameter(result, SqlDbType.Int, 8, ParameterDirection.Output, true, 0, 0, , DataRowVersion.Default, m_DBNull) ; /执行存储过程 try DAL.SQLHelper.ExecuteNonQuery(DAL.SQLHelper.CONN_STRING, Com _ndType.StoredPro _dure, GetBackPwd,

4、 para); catch throw new Ex _ption(邮件无法发送！); /获得输出参数的值 int result = Convert.ToInt32(para4.Value); /如果 _保护资料填写正确 if (result = 1) /从Web.config获取发信人地址、邮件标题、邮件用户名和 _以及SmtpServer string sender = System.Configuration.ConfigurationSettings.AppSettings _inSender; string title = System.Configuration.Configura

5、tionSettings.AppSettings _ilTitle; string _ilUser = System.Configuration.ConfigurationSettings.AppSettings _ilUser; string _ilPwd = System.Configuration.ConfigurationSettings.AppSettings _ilPwd; string _tpServer = System.Configuration.ConfigurationSettings.AppSettings _ilSmtpServer; /发信 try Mail.CDO

6、send _il(sender, e _il, title, 您在eshop的 _已找回,新 _为+newPassword , _ilUser, _ilPwd, _tpServer); catch(Ex _ption ex) throw new Ex _ption(ex.Message); return result; /随机生成 _ private static string MakePassword(int pwdLength) /声明要返回的字符串 string tmpstr = ; / _中包含的字符数组 string pwdchars=abcdefghijklmnopqrstuvwx

7、yz01234567 _ABCDEFGHIJKLMNORSTUVWXYZ; /数组索引随机数 int iRandNum; /随机数生成器 Random rnd = new Random(); for(int i=0;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 += pwdcharsiRandNum; return tmpstr; ALTER PROCEDURE GetBackPwd question nvarchar(50), answer nvarchar(50), userName nvarchar(50), newPassword nvarchar(50), result int output AS BEGIN SET RESULT = 1 UPDATE USERINFO SET USERPWD = newPassword WHERE
