Advance Email Sending(With Attachment) Code(C#.NET with ASP.NET) using gmail

      Advance Email Sending Option , with attachement.
Task: Sending Email with attachment using c# code in website/ web application.
Description: Some time we need to a website viewer can send a enquiry with some attachment as  some kind of career option where a candidate can submit his/her resume and the website administrator receive the same within email.

As in my previous post I discuss about a email notification without attachment option , Now we require a email with attachment, I use below code for sending email with attachment . Here I use two fileupload control for uploading attachment file (here I am not checking the extension of file / as you can check it first before sending email ).

// Below Function can be used for sending a email with attachment option using c# code
//  using gmail crdential
using System.Web.Mail;
public bool mailattachement2(string to, string replyto, string body, string subject, FileUpload f1, FileUpload f2)
        MailMessage mail = new MailMessage();
        mail.From = new MailAddress("","Client Enquiry");
        mail.Subject = subject;
        mail.Body = body;
        MailAddress rt = new MailAddress(replyto);
        mail.ReplyTo = rt;
        //mail.Sender = rt;
        mail.IsBodyHtml = true;
        if (f1.HasFile)
            mail.Attachments.Add(new Attachment(f1.PostedFile.InputStream, f1.FileName)); //add the attachment
        if (f2.HasFile)
            mail.Attachments.Add(new Attachment(f2.PostedFile.InputStream, f2.FileName)); //add the attachment

        SmtpClient smtp = new SmtpClient();
        smtp.Host = "";
        smtp.Credentials = new System.Net.NetworkCredential("", "password");
// Set the one email id and its password for authentication )
// email goes via using above email id...

        smtp.Port = 587;
        smtp.EnableSsl = true;
            return (true);
        catch (Exception ex)
            return (false);

    1. This blog is for developer, & I think above code is not a complicated code for explanation...

  3. Compiler Error Message: CS1518: Expected class, delegate, enum, interface, or struct

    1. If you just copy & paste this code then it will be give you error...:-)
      you have to add some namespaces also & a developer should be know that how can add these stuff...
