Using this code snippet user would be able to send an email with attachment through Outlook, Yahoo, AOL, HOTMAIL and Gmail.

Introduction

Using this code snippet user would be able to send an email with attachment through Outlook, Yahoo, AOL, HOTMAIL and Gmail.

Background

Already loads of information are available on internet for the same purpose. But not all the code is placed at one place. So here is my small effort to accumulate all the code at one place and that is nothing better than CodeProject. Hopefully it will be helpful for the beginners or whoever in needs of it.

Using the Code

Name Space

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Net.Mail;
using System.Net;
using Outlook = Microsoft.Office.Interop.Outlook;

Block Diagram(SMTP Setting for Various Client)

Below is the Block diagram for the SMTP settings i have used to send out an email from various client providers.

Wherever needed i have explain the code in details. The codes are self explanatory, any way for the same I have included comments. So here is the code snippet to achieve your purpose.

1. Using Outlook

To send an email using outlook, we need to add a reference to the dynamic link library for Outlook which is called Microsoft.Office.Interop.Outlook.dll

For the same follow the below steps:

  1. Go to your solution explorer
  2. Click on add a reference
  3. Click on .Net Tab
  4. Go through the DLL and select Microsoft.Office.Interop.Outlook.dll correctly.
  5. AddReferece.jpg

  6. when you have selected the correct reference you select the “OK” button and this reference will be added to your project under references.
  7. Mcrosoftdll.jpg

  8. Now we need to add a reference in our class to the Outlook reference we have added to the project in our previous example.
using Outlook = Microsoft.Office.Interop.Outlook;
And finally the code would look something like this:
                    
//method to send email to outlook
public void sendEMailThroughOUTLOOK()
{
    try
    {
    // Create the Outlook application.
    Outlook.Application oApp = new Outlook.Application();
    // Create a new mail item.
    Outlook.MailItem oMsg = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);
    // Set HTMLBody. 
    //add the body of the email
    oMsg.HTMLBody = "Hello, Jawed your message body will go here!!";
    //Add an attachment.
    String sDisplayName = "MyAttachment";
    int iPosition = (int)oMsg.Body.Length + 1;
    int iAttachType = (int)Outlook.OlAttachmentType.olByValue;
    //now attached the file
    Outlook.Attachment oAttach = oMsg.Attachments.Add(@"C:\\fileName.jpg", iAttachType, iPosition, sDisplayName);
    //Subject line
    oMsg.Subject = "Your Subject will go here.";
    // Add a recipient.
    Outlook.Recipients oRecips = (Outlook.Recipients)oMsg.Recipients;
    // Change the recipient in the next line if necessary.
    Outlook.Recipient oRecip = (Outlook.Recipient)oRecips.Add("jawed.ace@gmail.com");
    oRecip.Resolve();
    // Send.
    oMsg.Send();
    // Clean up.
    oRecip = null;
    oRecips = null;
    oMsg = null;
    oApp = null;
     }//end of try block
    catch (Exception ex)
    {
    }//end of catch
}//end of Email Method

2. Using HOTMAIL

To send an email using HotMail, we need to add a reference to the dynamic link library for Hotmail/Gmail/AOL/Yahoo which is called System.Net.Mail.

For the same follow the below steps:

  1. Go to solution explorer of your project
  2. Select add a reference
  3. Click on .Net Tab
  4. Go through the DLL and select System.Net.Mail.
  5. When you have selected the correct reference you select the “OK” button and this reference will
  6. be added to your projectunder references.

  7. Now we need to add a reference in our class to the Hotmail/gmail/aol/yahoo reference we have
added to the project.
using System.Net.Mail;
Note: The HOTMAIL SMTP Server requires an encrypted connection (SSL) on port 25.

And finally the code would look something like this:

//method to send email to HOTMAIL
public void sendEMailThroughHotMail()
{
    try
    { 
    //Mail Message
        MailMessage mM = new MailMessage();
        //Mail Address
        mM.From = new MailAddress("sender@hotmail.com");
        //receiver email id
        mM.To.Add("rcver@gmail.com");
        //subject of the email
        mM.Subject = "your subject line will go here";
        //deciding for the attachment
        mM.Attachments.Add(new Attachment(@"C:\\attachedfile.jpg"));
        //add the body of the email
        mM.Body = "Body of the email";
        mM.IsBodyHtml = true;
        //SMTP client
        SmtpClient sC = new SmtpClient("smtp.live.com");
        //port number for Hot mail
        sC.Port = 25;
        //credentials to login in to hotmail account
        sC.Credentials = new NetworkCredential("sender@hotmail.com","HotMailPassword");
        //enabled SSL
        sC.EnableSsl = true;
        //Send an email
        sC.Send(mM);
    }//end of try block
    catch (Exception ex)
    {
    
    }//end of catch
}//end of Email Method HotMail

3. Using Yahoo!

//Method to send email from YAHOO!!
public void sendEMailThroughYahoo()
{
    try
    {
        //mail message
        MailMessage mM = new MailMessage();
        //Mail Address
        mM.From = new MailAddress("sender@yahoo.com");
        //emailid to send
        mM.To.Add("recvEmailid@gmail.com");
        //your subject line of the message
        mM.Subject = "your subject line will go here.";
        //now attached the file
        mM.Attachments.Add(new Attachment(@"C:\\attachedfile.jpg"));
        //add the body of the email
        mM.Body = "Your Body of the email.";
        mM.IsBodyHtml = false;
        //SMTP 
        SmtpClient SmtpServer = new SmtpClient();
        //your credential will go here
        SmtpServer.Credentials = new System.Net.NetworkCredential("sender@yahoo.com", "password");
        //port number to login yahoo server
        SmtpServer.Port = 587;
        //yahoo host name
        SmtpServer.Host = "smtp.mail.yahoo.com";
        //Send the email
        SmtpServer.Send(mM);
    }//end of try block
    catch (Exception ex)
    {
    }//end of catch
}//end of Yahoo Email Method

4. Using AOL

//Method to send email from YAHOO!!
public void sendEMailThroughAOL()
{
    try
    {
         //mail message
        MailMessage mM = new MailMessage();
        //Mail Address
        mM.From = new MailAddress("sender@aol.com");
        //emailid to send
        mM.To.Add("recvEmailid@gmail.com");
        //your subject line of the message
        mM.Subject = "your subject line will go here.";
        //now attached the file
        mM.Attachments.Add(new Attachment(@"C:\\attachedfile.jpg"));
        //add the body of the email
        mM.Body = "Your Body of the email.";
        mM.IsBodyHtml = false;
        //SMTP 
        SmtpClient SmtpServer = new SmtpClient();
        //your credential will go here
        SmtpServer.Credentials = new System.Net.NetworkCredential("sender@aol.com", "AOLpassword");
        //port number to login yahoo server
        SmtpServer.Port = 587;
        //yahoo host name
        SmtpServer.Host = "smtp.aol.com";
        //Send the email
        SmtpServer.Send(mM);
    }//end of try block
    catch (Exception ex)
    {
 
    }//end of catch
}//end of AOLEmail Method

5. Using Gmail

Note: The GMAIL SMTP Server requires an encrypted connection (SSL) on port 487.
//method to send email to Gmail
public void sendEMailThroughGmail()
{
    try
    {
        //Mail Message
        MailMessage mM = new MailMessage();
        //Mail Address
        mM.From = new MailAddress("sender@gmail.com");
        //receiver email id
        mM.To.Add("rcver@gmail.com");
        //subject of the email
        mM.Subject = "your subject line will go here";
        //deciding for the attachment
        mM.Attachments.Add(new Attachment(@"C:\\attachedfile.jpg"));
        //add the body of the email
        mM.Body = "Body of the email";
        mM.IsBodyHtml = true;
        //SMTP client
        SmtpClient sC = new SmtpClient("smtp.gmail.com");
        //port number for Gmail mail
        sC.Port = 587;
        //credentials to login in to Gmail account
        sC.Credentials = new NetworkCredential("sender@gmail.com", "GmailPassword");
        //enabled SSL
        sC.EnableSsl = true;
        //Send an email
        sC.Send(mM);
    }//end of try block
    catch (Exception ex)
    {
 
    }//end of catch
}//end of Email Method
Already I am using the above code snippet for my automation purpose and its working fine for me!!
