HOW TO UPLOAD AN IMAGE WHILE SENDING AND EMAIL USING ASP.NET

HERE IN THIS ASP.NET Tutorial WE WILL UPLOAD AN IMAGE WHILE SENDING AND EMAIL USING ASP.NET

Here, we will see how can we send email using our Gmail SMTP in c# .NET. Generally, for sending an email from one place to another two parties are required -- first is the sender and the second is the receiver. We will use the Mail Message class of .NET to send an email. For this, we will require a few details:

Sender Email Address

Sender Password

Receiver Email Address

Port Number

EnableSSL property

And most important before we start coding we need to import two namespaces to access the MailMessage Class:

using System.Net;

using System.Net.Mail;

SMTP Class Properties

Following are the properties of the SMTP class.

Host – SMTP Server URL (Gmail: smtp.gmail.com)

EnableSsl – Specify whether your host accepts SSL Connections (Gmail: True)

UseDefaultCredentials – Set to True in order to allow authentication based on the Credentials of the Account used to send emails

Credentials – Valid login credentials for the SMTP server (Gmail: email address and password)

Port – Port Number of the SMTP server (Gmail: 587)

Step 1 :- WebForm2.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="WebApplication6.WebForm2" %>

<!DOCTYPE html>

.auto-style1 {

width: 344px;

}

.auto-style2 {

width: 121%;

}

</style>

</head>

<div>

<tr>

<asp:Label ID="Label1" runat="server" Text="FROM :-"></asp:Label>

</td>

<td>

<asp:TextBox ID="TextBox1" runat="server" Width="246px"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Label ID="Label2" runat="server" Text="TO :-"></asp:Label>

</td>

<td>

<asp:TextBox ID="TextBox2" runat="server" Width="246px"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Label ID="Label3" runat="server" Text="UPLOAD IMAGE :-"></asp:Label>

</td>

<td>

<asp:FileUpload ID="FileUpload1" runat="server" />

</td>

</tr>

<tr>

</tr>

<tr>

<asp:Label ID="Label7" runat="server" Text="VISITOR CONTACT NO :-"></asp:Label>

</tr>

<tr>

<asp:Label ID="Label8" runat="server" Text="MEETING TO :-"></asp:Label>

</td>

<td>

<asp:TextBox ID="TextBox6" runat="server" Width="246px"></asp:TextBox>

</td>

</tr>

<tr>

<td>

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="SUBMIT" />

</td>

</tr>

<tr>

<td>

<asp:Label ID="Label4" runat="server" ForeColor="Lime"></asp:Label>

</td>

</tr>

</table>

</div>

</form>

</body>

</html>

Step 2 :- C# Code

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.IO;

using System.Net;

using System.Net.Mail;

namespace WebApplication6

{

public partial class WebForm2 : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void Button1_Click(object sender, EventArgs e)

{

string folderPath = Server.MapPath("~/Files/");

if (!Directory.Exists(folderPath))

{

Directory.CreateDirectory(folderPath);

}

FileUpload1.SaveAs(folderPath + Path.GetFileName(FileUpload1.FileName));

string text = @"<html><body>" +

"<h3><b>This Person Is Coming For Official Visit.</b></h3>" +

"<table>" +

"<tr><td width=150px>Visitor Image :</td><td><img src='cid:image1' height=70px width=70px></td></tr>" +

"<tr><td width=150px>Visitor Name :</td><td>" + TextBox3.Text.ToString() + "</td></tr>" +

"<tr><td width=150px>Visitor Company :</td><td>" + TextBox4.Text.ToString() + "</td></tr>" +

"<tr><td width=150px>Visitor ContactNo :</td><td>" + TextBox5.Text.ToString() + "</td></tr>" +

"<tr><td width=150px>Meeting To :</td><td>" + TextBox6.Text.ToString() + "</td></tr>" +

"<tr><td width=150px>Purpose :</td><td>Official Visit</td></tr>" +

"<tr><td width=150px>Date :</td><td>" + System.DateTime.Now.ToString() + "</td></tr>" +

"</table>" +

"</body></html>";

using (MailMessage mm = new MailMessage(TextBox1.Text.ToString(), TextBox2.Text.ToString()))

{

AlternateView htmlview = default(AlternateView);

htmlview = AlternateView.CreateAlternateViewFromString(text, null, "text/html");

LinkedResource imageResourceEs = new LinkedResource(Server.MapPath("~/Files/" + FileUpload1.FileName.ToString()), "image/jpg");

imageResourceEs.ContentId = "image1";

imageResourceEs.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;

htmlview.LinkedResources.Add(imageResourceEs);

mm.Subject = "Visitor Notification";

mm.Body = text;

mm.IsBodyHtml = true;

mm.AlternateViews.Add(htmlview);

using (SmtpClient smtp = new SmtpClient())

{

smtp.Host = "smtp.gmail.com";

smtp.EnableSsl = true;

NetworkCredential NetworkCred = new NetworkCredential("[email protected]","password");

smtp.UseDefaultCredentials = true;

smtp.Credentials = NetworkCred;

smtp.Port = 587;

smtp.Send(mm);

Label4.Text = "Email Sent";

}
