如何使用C#通过MVC-3 asp.net发送邮件?
How to send a mail through mvc-3 asp.net using c#?
我要送一个忘记密码,所以我怎么能做到这一点?
我的code如下。
I have to send a forgot password so how can I do this? My code is below.
示范code ..
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
namespace TelerikLogin.Models.ViewModels
{
public class ForgotPassword
{
public int user_id { get; set; }
public string user_login_name { get; set; }
public string user_password { get; set; }
[Required]
[Display(Name="Email Address : ")]
public string user_email_address { get; set; }
}
}
控制器code ..
Controller code..
public ActionResult ForgotPassword()
{
return View();
}
[HttpPost]
public ActionResult ForgotPassword(string user_email_address)
{
SqlConnection conn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=E:\MVC3\TelerikLogin\TelerikLogin\App_Data\Login.mdf;Integrated Security=True;User Instance=True");
DataTable dt1 = new DataTable();
string strQuery = string.Format("SELECT user_password FROM [user_master] WHERE user_email_address='{0}'",user_email_address);
conn.Open();
SqlDataAdapter da1 = new SqlDataAdapter(strQuery, conn);
da1.Fill(dt1);
conn.Close();
if (dt1.Rows.Count > 0)
{
MailMessage msg = new MailMessage();
msg.From = new MailAddress("abc@gmail.com");
msg.To.Add(user_email_address);
msg.Subject = "Password";
msg.Body = "Test1";
msg.Priority = MailPriority.High;
SmtpClient client = new SmtpClient();
client.Credentials = new NetworkCredential("abc@gmail.com", "disha", "smtp.gmail.com");
client.Host = "smtp.gmail.com";
client.Port = 587;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.EnableSsl = true;
client.UseDefaultCredentials = true;
client.Send(msg);
return RedirectToAction("About", "Home");
}
return View();
}
下面我通过输入的电子邮件地址获取用户从数据库中的密码。
Here I fetched the password of user from database through entered email address..
查看code ..
<% using (Html.BeginForm("ForgotPassword", "Account", FormMethod.Post))
{ %>
<%: Html.LabelFor(m => m.user_email_address) %>
<%: Html.TextBox("user_email_address")%>
<%: Html.ValidationSummary(true) %>
<input type="submit" value="Submit"/>
<%} %>
它给了我一个错误在这些行
It gives me an error on these line
client.Send(msg);
错误messege是:
Error messege is:
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. x1sm1264662igc.16
如何解决呢?
在此先感谢
How to solve it? thanks in advance
推荐答案
导入 System.Net.Mail
命名空间。
在code将类似于这样:
The code will look similar to this:
MailMessage mail = new MailMessage();
SmtpClient smtpServer = new SmtpClient("smtp.gmail.com");
smtpServer.Credentials = new System.Net.NetworkCredential("userName", "password");
smtpServer.Port = 587; // Gmail works on this port
mail.From = new MailAddress("myemail@gmail.com");
mail.To.Add("recepient@gmail.com");
mail.Subject = "Password recovery";
mail.Body = "Recovering the password";
smtpServer.Send(mail);
P.S。你必须在样本code SQL注入漏洞。使用带有参数,而不是的String.Format()
。
使用 SqlDataReader的
将是一个很大更有效率的检查记录,而不是填充的DataSet
。
Using SqlDataReader
would be a lot more efficient to check for a record instead of populating a DataSet
.
