How to send email in ASP.NET C#

asp.net, c#, email, smtp

Solution

Just go through the below code.

SmtpClient smtpClient = new SmtpClient("mail.MyWebsiteDomainName.com", 25);

smtpClient.Credentials = new System.Net.NetworkCredential("info@MyWebsiteDomainName.com", "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("MyEmailID@gmail.com"));

smtpClient.Send(mail);

Problem

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.
