如何在ASP.NET C＃中发送电子邮件
我很新的ASP.NET C＃领域。 我打算通过ASP.NET C＃发送邮件，这是我的ISP的SMTP地址：
smtp-proxy.tm.net.my 以下是我试图做的，但失败了。
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="SendMail" %> <html> <head id="Head1" runat="server"><title>Email Test Page</title></head> <body> <form id="form1" runat="server"> Message to: <asp:TextBox ID="txtTo" runat="server" /><br> Message from: <asp:TextBox ID="txtFrom" runat="server" /><br> Subject: <asp:TextBox ID="txtSubject" runat="server" /><br> Message Body:<br> <asp:TextBox ID="txtBody" runat="server" Height="171px" TextMode="MultiLine" Width="270px" /><br> <asp:Button ID="Btn_SendMail" runat="server" onclick="Btn_SendMail_Click" Text="Send Email" /><br> <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> </form> </body> </html>
下面是我的代码隐藏 ：
using System; using System.Web.UI.WebControls; using System.Net.Mail; public partial class SendMail : System.Web.UI.Page { protected void Btn_SendMail_Click(object sender, EventArgs e) { MailMessage mailObj = new MailMessage( txtFrom.Text, txtTo.Text, txtSubject.Text, txtBody.Text); SmtpClient SMTPServer = new SmtpClient("127.0.0.1"); try { SMTPServer.Send(mailObj); } catch (Exception ex) { Label1.Text = ex.ToString(); } } }
PS：很抱歉，我无法理解接收者/发送者的SMTP概念，所以我想从这里理解整个概念。
只要通过下面的代码。
SmtpClient smtpClient = new SmtpClient("mail.MyWebsiteDomainName.com", 25); smtpClient.Credentials = new System.Net.NetworkCredential("info@MyWebsiteDomainName.com", "myIDPassword"); smtpClient.UseDefaultCredentials = true; smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network; smtpClient.EnableSsl = true; MailMessage mail = new MailMessage(); //Setting From , To and CC mail.From = new MailAddress("info@MyWebsiteDomainName", "MyWeb Site"); mail.To.Add(new MailAddress("info@MyWebsiteDomainName")); mail.CC.Add(new MailAddress("MyEmailID@gmail.com")); smtpClient.Send(mail);
尝试使用此代码，而不是：
protected void btn_send_Click(object sender, EventArgs e) { System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage(); mail.To.Add("to gmail address"); mail.From = new MailAddress("from gmail address", "Email head", System.Text.Encoding.UTF8); mail.Subject = "This mail is send from asp.net application"; mail.SubjectEncoding = System.Text.Encoding.UTF8; mail.Body = "This is Email Body Text"; mail.BodyEncoding = System.Text.Encoding.UTF8; mail.IsBodyHtml = true; mail.Priority = MailPriority.High; SmtpClient client = new SmtpClient(); client.Credentials = new System.Net.NetworkCredential("from gmail address", "your gmail account password"); client.Port = 587; client.Host = "smtp.gmail.com"; client.EnableSsl = true; try { client.Send(mail); Page.RegisterStartupScript("UserMsg", "<script>alert('Successfully Send...');if(alert){ window.location='SendMail.aspx';}</script>"); } catch (Exception ex) { Exception ex2 = ex; string errorMessage = string.Empty; while (ex2 != null) { errorMessage += ex2.ToString(); ex2 = ex2.InnerException; } Page.RegisterStartupScript("UserMsg", "<script>alert('Sending Failed...');if(alert){ window.location='SendMail.aspx';}</script>"); } }
注意：在“发件人地址”中input正确的电子邮件地址和密码。 如果您有任何疑问与我联系。
你可以尝试这样使用hotmail这样的： –
MailMessage o = new MailMessage("From", "To","Subject", "Body"); NetworkCredential netCred= new NetworkCredential("Sender Email","Sender Password"); SmtpClient smtpobj= new SmtpClient("smtp.live.com", 587); smtpobj.EnableSsl = true; smtpobj.Credentials = netCred; smtpobj.Send(o);
尝试以下操作：
try { var fromEmailAddress = ConfigurationManager.AppSettings["FromEmailAddress"].ToString(); var fromEmailDisplayName = ConfigurationManager.AppSettings["FromEmailDisplayName"].ToString(); var fromEmailPassword = ConfigurationManager.AppSettings["FromEmailPassword"].ToString(); var smtpHost = ConfigurationManager.AppSettings["SMTPHost"].ToString(); var smtpPort = ConfigurationManager.AppSettings["SMTPPort"].ToString(); string body = "Your registration has been done successfully. Thank you."; MailMessage message = new MailMessage(new MailAddress(fromEmailAddress, fromEmailDisplayName), new MailAddress(ud.LoginId, ud.FullName)); message.Subject = "Thank You For Your Registration"; message.IsBodyHtml = true; message.Body = body; var client = new SmtpClient(); client.Credentials = new NetworkCredential(fromEmailAddress, fromEmailPassword); client.Host = smtpHost; client.EnableSsl = true; client.Port = !string.IsNullOrEmpty(smtpPort) ? Convert.ToInt32(smtpPort) : 0; client.Send(message); } catch (Exception ex) { throw (new Exception("Mail send failed to loginId " + ud.LoginId + ", though registration done.")); }
然后在你的web.config之间添加下面的内容
<!--Email Config--> <add key="FromEmailAddress" value="sender emailaddress"/> <add key="FromEmailDisplayName" value="Display Name"/> <add key="FromEmailPassword" value="sender Password"/> <add key="SMTPHost" value="smtp-proxy.tm.net.my"/> <add key="SMTPPort" value="smptp Port"/>

using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Net.Mail; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void btnSubmit_Click(object sender, EventArgs e) { try { MailMessage message = new MailMessage(txtFrom.Text, txtTo.Text, txtSubject.Text, txtBody.Text); SmtpClient emailClient = new SmtpClient(txtSMTPServer.Text); emailClient.Send(message); litStatus.Text = "Message Sent"; } catch (Exception ex) { litStatus.Text=ex.ToString(); } } }
这对我来说是完美的。
public void sendEmail(string body) { if (String.IsNullOrEmpty(email)) return; try { MailMessage mail = new MailMessage(); mail.To.Add(email); mail.To.Add("test@gmail.com"); mail.From = new MailAddress("abc@gmail.com"); mail.Subject = "sub"; mail.Body = body; mail.IsBodyHtml = true; SmtpClient smtp = new SmtpClient(); smtp.Host = "smtp.gmail.com"; //Or Your SMTP Server Address smtp.Credentials = new System.Net.NetworkCredential ("yourgmail@gmail.com", "Yourpassword"); // ***use valid credentials*** smtp.Port = 587; //Or your Smtp Email ID and Password smtp.EnableSsl = true; smtp.Send(mail); } catch (Exception ex) { print("Exception in sendEmail:" + ex.Message); } }
MailMessage mm = new MailMessage(txtEmail.Text, txtTo.Text); mm.Subject = txtSubject.Text; mm.Body = txtBody.Text; if (fuAttachment.HasFile)//file upload select or not { string FileName = Path.GetFileName(fuAttachment.PostedFile.FileName); mm.Attachments.Add(new Attachment(fuAttachment.PostedFile.InputStream, FileName)); } mm.IsBodyHtml = false; SmtpClient smtp = new SmtpClient(); smtp.Host = "smtp.gmail.com"; smtp.EnableSsl = true; NetworkCredential NetworkCred = new NetworkCredential(txtEmail.Text, txtPassword.Text); smtp.UseDefaultCredentials = true; smtp.Credentials = NetworkCred; smtp.Port = 587; smtp.Send(mm); Response.write("Send Mail");

如果你想用剃刀生成你的电子邮件正文，你可以使用Mailzory 。 另外，你可以从这里下载nuget软件包。
// template path var viewPath = Path.Combine("Views/Emails", "hello.cshtml"); // read the content of template and pass it to the Email constructor var template = File.ReadAllText(viewPath); var email = new Email(template); // set ViewBag properties email.ViewBag.Name = "Johnny"; email.ViewBag.Content = "Mailzory Is Funny"; // send email var task = email.SendAsync("mailzory@outlook.com", "subject"); task.Wait()
