如何在ASP.NET中的电子邮件中向用户发送密码 [英] How to send Password to user in an Email in ASP.NET

问题描述

我有一个表单，我有一个文本框供用户输入他们的电子邮件地址，以便他们可以获取他们的密码，如果他们忘记了，发送到用户的电子邮件。我有代码，但它似乎不起作用。我有一个电子邮件服务器。邮件服务器是mail.fastfix.com。我的代码有什么问题，电子邮件无法发送？

I have a form that I have a textbox for the user to enter their email address so that they can get their password, if they forget it, sent to the user email. I have the code but it doesn't seem to work. I have a mail server for the emails. Mail server is mail.fastfix.com. What is wrong in my code the reason why the email won't send?

using System;
using System.Data.SqlClient;
using System.Configuration;
using System.Data;
using System.Net.Mail;

public partial class ForgotPassword : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btnPass_Click(object sender, EventArgs e)
    {
        //Create Connection String And SQL Statement
        string strConnection = ConfigurationManager.ConnectionStrings["HotConnectionString"].ConnectionString;
        string strSelect = "SELECT EmailAddress, Password FROM Tablepass WHERE EmailAddress ='" + TextBoxEA.Text + "'";

        SqlConnection connection = new SqlConnection(strConnection);
        SqlCommand command = new SqlCommand();
        command.Connection = connection;
        command.CommandType = CommandType.Text;
        command.CommandText = strSelect;

        SqlParameter email = new SqlParameter("@EmailAddress", SqlDbType.VarChar, 50);
        email.Value = TextBoxEA.Text.Trim().ToString();
        command.Parameters.Add(email);

        //Create Dataset to store results and DataAdapter to fill Dataset 
        DataSet dsPwd = new DataSet();
        connection.Open();
        SqlDataAdapter dAdapter = new SqlDataAdapter(command);
        dAdapter.Fill(dsPwd);
        connection.Close();
        if (dsPwd.Tables[0].Rows.Count > 0)
        {
            MailMessage loginInfo = new MailMessage();
            loginInfo.To.Add(TextBoxEA.Text.ToString());
            loginInfo.From = new MailAddress("[e-mail]");
            loginInfo.Subject = "Forgot Password Information";

            loginInfo.Body = "EmailAddress: " + dsPwd.Tables[0].Rows[0]["EmailAddress"] + "<br /><br />Password: " + dsPwd.Tables[0].Rows[0]["Password"] + "<br /><br />";
            loginInfo.IsBodyHtml = true;
            SmtpClient smtp = new SmtpClient();
            smtp.Host = "smtp.mail.fastfix.com";
            smtp.Port = 25;
            smtp.EnableSsl = true;
            smtp.Credentials = new System.Net.NetworkCredential("[e-mail]", "YourEmailPassword");
            smtp.Send(loginInfo);
            lblMessage.Text = "Password is sent to you email id,you can now <a href='Login.aspx'>Login</a>";

            try
            {
                smtp.Send(loginInfo);
            }
            catch (Exception ex)
            {

                lblMessage.Text = "Oops, Something Went Wrong When We Tried to Send The Email";
                return;
            }

        }
        else
        {
            lblMessage.Text = "Email Address Not Registered";
        }

    }

    
}

推荐答案

选中收件人字段，确保电子邮件地址的格式正确，且该字段不为空。
