代码执行，但不在收件箱中接收邮件
本文关键字：收件箱 执行 代码 | 更新日期: 2023-09-27 17:57:12
>我已经编写了用于发送电子邮件的代码，虽然代码成功执行，但收件箱中未收到邮件。请帮助我并更正代码;我的错误在哪里，或者为什么收件箱中没有收到邮件？
这是我的代码，请告诉我问题是什么。
我正在从事忘记密码和用户名发送给输入电子邮件ID的用户的项目。
protected void Button2_Click(object sender, EventArgs e)
{
string email = TextBox1.Text;
SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=regester;Integrated Security=True");
string command = "select id,password,email from reg ";
SqlCommand sqlcmd = new SqlCommand(command, con);
//sqlcmd.Parameters["@Email"].Value = email;
//sqlcmd.Parameters.Add("@Email", email);
con.Open();
if (con.State == ConnectionState.Open)
{
SqlDataReader dtr = sqlcmd.ExecuteReader();
while (dtr.Read())
{
if (dtr[2].ToString().Equals(TextBox1.Text))
{
MailMessage mail = new MailMessage();
mail.To.Add(dtr[2].ToString());
mail.From = new MailAddress("mian722@hotmail.com");
mail.Subject = "Your userId and Password";
mail.Body = "Your<br/> UserId:<b>" + dtr[0].ToString() + "</b><br/>" + "Password:<b>" + dtr[1].ToString() + "</b>";
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.Credentials = new System.Net.NetworkCredential("your id", "your password");
smtp.EnableSsl = true;
//smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
//smtp.EnableSsl = true;
//smtp.UseDefaultCredentials = true;
smtp.EnableSsl = true; //Gmail works on Server Secured Layer
try
{
smtp.Send(mail);
}
catch (Exception ex)
{
}
//smtp.Send(mail);
Label1.Text = "check your mailbox for user iD and Password";
string javaScript = "<script language=JavaScript>'n" + "alert('User Id and password send to Your mail box');'n" + "</script>";
RegisterStartupScript("xyz", javaScript);
break;
}
else
{
Label1.Text = "Email Id not valid";
}
}
}
}
}
此行丢弃Send引发的任何异常。删除尝试和捕获，放置某种日志记录，甚至只是在其上放置一个断点。然后，希望您能告诉我们例外是什么。
try
{
smtp.Send(mail);
}
catch (Exception ex)
{
}
您可能希望在错误处理中更具体，至少在找到问题之前
