如何使用c＃？
通过mvc-3 asp.net发送邮件我必须发送一个忘记的密码，以便我该怎么做？ 我的代码如下。
模型代码..
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; }
}
}
控制器代码..
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", "dip", "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();
}
在这里，我通过输入的电子邮件地址从数据库中获取了用户的密码..
查看代码..
<% 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"/>
<%} %>
它在这些行上给我一个错误
client.Send(msg);
错误消息是：
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？ 提前谢谢

导入System.Net.Mail命名空间。
代码看起来与此类似：
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。您在示例代码中有一个SQL注入漏洞。使用带参数的SqlCommand对象而不是String.Format()。
使用SqlDataReader可以更有效地检查记录，而不是填充DataSet。

你可以用这个......
public void SendEmail(string address, string subject, string message)
{
string email = "-your-id-@gmail.com";
string password = "put-your-GMAIL-password-here";
var loginInfo = new NetworkCredential(email, password);
var msg = new MailMessage();
var smtpClient = new SmtpClient("smtp.gmail.com", 587);
msg.From = new MailAddress(email);
msg.To.Add(new MailAddress(address));
msg.Subject = subject;
msg.Body = message;
msg.IsBodyHtml = true;
smtpClient.EnableSsl = true;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = loginInfo;
smtpClient.Send(msg);
}

我在ASP.net MVC3中用它来发送电子邮件
System.Web.Helpers.WebMail.SmtpServer = smtp_server;
System.Web.Helpers.WebMail.SmtpPort = smtp_port;
System.Web.Helpers.WebMail.EnableSsl = true;
System.Web.Helpers.WebMail.From = "fromaddress";
StringBuilder sb = new StringBuilder();
sb.Append("<table><tr><td>");
sb.Append(msg);
sb.Append("</td></tr></table>");
string body = sb.ToString();
string To = toemail;
System.Web.Helpers.WebMail.Send(To,subject, body);

Using Systems.Net.Mail;
// POST: /Account/Register
//Here's a simple Mail(MVC4)
public async Task<ActionResult> Register(RegisterViewModel model)
{
Mail email= new Mail();
if (ModelState.IsValid)
{
var user = new ApplicationUser() { UserName = model.UserName, Email = model.Email };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
email.to = new MailAddress(model.Email);
email.body = "Hello " + model.Firstname + " your account has been created <br/> Username: " + model.UserName + " <br/>Password: " + model.Password.ToString() + " <br/> change it on first loggin";
ViewBag.Feed = email.reg();
await SignInAsync(user, isPersistent: false);
return RedirectToAction("Index", "Home");
}
else
{
AddErrors(result);
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
//Business Logic(this Is you Email Class)
Using Systems.Net.Mail;
public class Mail
{
public MailAddress to { get; set; }
public MailAddress from { get; set; }
public string sub { get; set; }
public string body { get; set; }
public string reg()

string feed = "Registration Successful";
var m = new System.Net.Mail.MailMessage()
{
Subject = "",
Body = body,
IsBodyHtml = true
};
m.From = new MailAddress("Mxolisi@gmail.com ", "Administrator");
m.To.Add(to);
SmtpClient smtp = new SmtpClient
{
Host = "pod51014.outlook.com",
//Host = "smtp-mail.outlook.com",
Port = 587,
Credentials = new System.Net.NetworkCredential("Mxolisi@gmail.com ", " Dut324232"),
EnableSsl = true
};
try
{
smtp.Send(m);
// feed = "";
}
catch (Exception e)
{
}
return feed;
}
public string fogot()
{
string feedback = "";
var m = new System.Net.Mail.MailMessage()
{
Subject = "Reset Password PIN",
Body = body,
IsBodyHtml = true
};
m.From = new MailAddress("Mxolisi@gmail.com ", "Administrator");
m.To.Add(to);
SmtpClient smtp = new SmtpClient

}
catch (Exception e)

看起来您正试图通过GMail的SMTP服务发送电子邮件，这个问题已经涵盖了这个问题：Sending email in .NET through Gmail
您的代码中唯一缺少的是您已设置client.UseDefaultCredentials = true，我认为您要将其设置为false并提供您自己的凭据。我从未尝试使用GMail通过电子邮件发送，但我猜你需要使用GMail帐户作为您的凭据才能正确验证。

您应该在Window 7中打开SMTP服务：

当使用smtp for gmail时，记得把
smtpClient.UseDefaultCredentials = false;
前
smtpClient.Credentials = loginInfo;
