} --------------------编程问答-------------------- 注册时发送到邮箱去
C# code
public void sendEmail(string email, string name)
{
try
{
jmail.Message jmessage = new jmail.Message();
jmessage.Charset = "GB2312";
jmessage.From = new functions().getInfoXX("t_Parameters", "p_name", "网站电子邮箱", "p_value").Trim();
// 发信地址
jmessage.MailServerUserName = new functions().getInfoXX("t_Parameters", "p_name", "网站电子邮箱", "p_value").Trim();
//smtp认证用户名(注:如为网易用户,不加要@163.com,只要前面部分即可)
jmessage.MailServerPassWord = new functions().getInfoXX("t_Parameters", "p_name", "网站电子邮箱密码", "p_value").Trim();
// smtp论证用户名密码
jmessage.FromName = "108人力银行";
// 发信人
jmessage.ReplyTo = new functions().getInfoXX("t_Parameters", "p_name", "网站电子邮箱", "p_value");
// 回复地址
jmessage.ContentType = "text/html";//邮件内容为html
jmessage.Subject = "您已成功注册108人力银行个人会员";
//string strbody = "<br>" + name + "您好！<br><br> 欢迎您注册108人力银行个人会员。<br><br><br><br> 108人力银行个人会员<br><br> "+DateTime.Now.Date;//邮件内容
string strbody = "";
strbody += new functions().getInfoXX("t_pagetexts", "p_name", "个人注册邮件反馈","p_value").Replace("$",name);
jmessage.HTMLBody = strbody;
// 邮件标题
jmessage.AddRecipient(email, "", "");
jmessage.Send("mail.108ren.com", false);//发送邮件smtp.163.com
jmessage.Close();//关闭对象,释放资源
}
catch (Exception err)
{
Response.Write(err);
}
使用方法是 this.sendEmail(email.Text.Trim(),username.Text.Trim());邮箱和用户名文本框
new functions().getInfoXX的方法是
/// table：表 /// bm：where条件中的数据表字段名称/// bmvalue：where 条件中的数据表字段内容
/// tname：需要查询的表字段名称
public string getInfoXX(string table, string bm, string bmvalue, string tname)
{
DBconn DB = new DBconn();
string bh = DB.getExecuteString("select " + tname + " from " + table + " where " + bm + "='" + bmvalue + "'");
return bh;
}
下面的是找回密码时发送到用户邮箱代码使用方法和上面的一样
C# code
public void sendEmail(string email, string name)
{
try
{
jmail.Message jmessage = new jmail.Message();
jmessage.Charset = "GB2312";
jmessage.From = "86085005@163.com";
// 发信地址
jmessage.MailServerUserName = "86085005";
//smtp认证用户名(注:如为网易用户,不加要@163.com,只要前面部分即可)
jmessage.MailServerPassWord = "kingseer";
// smtp论证用户名密码
jmessage.FromName = "108人力银行";
// 发信人
jmessage.ReplyTo = "86085005@163.com";
// 回复地址
jmessage.ContentType = "text/html";//邮件内容为html
jmessage.Subject = "108人力银行临时密码";
string strbody = "";
strbody += new functions().getInfoXX("t_pagetexts", "p_name", "找回密码邮件反馈-个人", "p_value").Replace("$", name).Replace("@%", lspass);
jmessage.HTMLBody = strbody;
// 邮件标题
jmessage.AddRecipient(email, "", "");
jmessage.Send("smtp.163.com", false);//发送邮件smtp.163.com
jmessage.Close();//关闭对象,释放资源
}
catch (Exception err)
{
Response.Write(err);
}
}
