I'm very new to the ASP.NET C# area. I'm planning to send a mail through ASP.NET C# and this is the SMTP address from my ISP:
smtp-proxy.tm.net.my Below is what I tried to do, but failed.
<%@ 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> And below is my code-behind:
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: I'm sorry that I couldn't understand the receiver/sender SMTP concept, and so I am trying to understand the whole concept from here.

For sending email we need a SMTP Server, so in ASP.Net we have the SmtpClient class, using that class object we set its properties for the SMTP settings. SmtpClient client = newSmtpClient("smtp.gmail.com", 587);
Provide the project a name, such as "Sending Emails" or another as you wish and specify the location. Then right-click on Solution Explorer and seelct "Add New Item" - "Default. aspx" page and one class file. Drag and drop three Text Boxes and two buttons.
The standard approach to send an email using C# is SMTP (Simple Mail Transfer Protocol). It is a network protocol used to send emails over the internet. Additionally, it allows you to relayemails across multiple networks.
NET and . NET Core come with built-in support for sending emails through the System. Net.Mail namespace. While it might seem like the easy choice, you will need an SMTP server for this to work.
Just go through the below code.
SmtpClient smtpClient = new SmtpClient("mail.MyWebsiteDomainName.com", 25); smtpClient.Credentials = new System.Net.NetworkCredential("[email protected]", "myIDPassword"); // smtpClient.UseDefaultCredentials = true; // uncomment if you don't want to use the network credentials 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("[email protected]")); smtpClient.Send(mail); Try using this code instead. Note: In the "from address" give your correct email id and password.
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>"); } } If you love us?
