using System.Net.Mail;

using System.Net.Mime;

MailMessage mail = new MailMessage();

//set the addresses

mail.From = new MailAddress("xx@xxx.com");

mail.To.Add("xx@xxx.com");

//set the content

mail.Subject = "Test";

//first we create the Plain Text part

AlternateView plainView = AlternateView.CreateAlternateViewFromString("This is my text , viewable by those clients that don't support html", null, "text/plain");

string htmlView1 = "This is my text , viewable by those clients that don't support html";

//then we create the Html part

//to embed images, we need to use the prefix 'cid' in the img src value

//the cid value will map to the Content-Id of a Linked resource.

//thus <img src='cid:logo'> will map to a LinkedResource with a ContentId of 'companylogo'

AlternateView htmlView = AlternateView.CreateAlternateViewFromString(htmlView1 + "<a href = "" ><img src="cid:logo" /></a>", null, System.Net.Mime.MediaTypeNames.Text.Html);

//create the LinkedResource (embedded image)

string path = Server.MapPath(@"Images/logo.jpg");

// LinkedResource logo = new LinkedResource(path);

LinkedResource logo = new LinkedResource(path, "image/jpeg");

logo.ContentId = "logo";

//add the LinkedResource to the appropriate view

htmlView.LinkedResources.Add(logo);

//add the views

mail.AlternateViews.Add(plainView);

mail.AlternateViews.Add(htmlView);

mail.IsBodyHtml = true;

//send the message

SmtpClient smtp = new SmtpClient();//"127.0.0.1"); //specify the mail server address

smtp.Send(mail);
