I want to send email with alternate views either plain text or html template, i have used code from the following linkaspnet-sending-email-both-in-html-and-plain-text but i dont know why its not working for me.. my code is:. public void EmailSendingWithBothHTMLAndPlainText(){ // CREATE EMAIL // first we create a plain text version and set it to the AlternateView // then we create the HTML version System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage(); msg.From = new MailAddress("[email protected]"); msg.Subject = "Event: testing"; msg.To.Add("[email protected]"); // create a string to hold all email addresses StringBuilder sbEmailTo = new StringBuilder(); sbEmailTo.Append("[email protected]"); //if (!String.IsNullOrEmpty(TextBoxEmail2.Text)) { msg.To.Add(TextBoxEmail2.Text); sbEmailTo.Append(", " + TextBoxEmail2.Text); } //if (!String.IsNullOrEmpty(TextBoxEmail3.Text)) { msg.To.Add(TextBoxEmail3.Text); sbEmailTo.Append(", " + TextBoxEmail3.Text); } //if (!String.IsNullOrEmpty(TextBoxEmail4.Text)) { msg.To.Add(TextBoxEmail4.Text); sbEmailTo.Append(", " + TextBoxEmail4.Text); } //if (!String.IsNullOrEmpty(TextBoxEmail5.Text)) { msg.To.Add(TextBoxEmail5.Text); sbEmailTo.Append(", " + TextBoxEmail5.Text); } //now create the HTML version MailDefinition message = new MailDefinition(); message.BodyFileName = "RegisterUser.html"; message.IsBodyHtml = true; message.From = "[email protected]"; message.Subject = "Zoo Event: " + "testing for HTML"; //embed images for the email //EmbeddedMailObject emo = new EmbeddedMailObject(); //emo.Path = @"~\Images\email\hdr_roar.gif"; //emo.Name = "hdr"; //EmbeddedMailObject emo2 = new EmbeddedMailObject(); ////emo2.Path = @"~\Images\email\box_top.gif"; //emo2.Name = "box_top"; //message.EmbeddedObjects.Add(emo); //message.EmbeddedObjects.Add(emo2); //Build replacement collection to replace fields in email.htm file ListDictionary replacements = new ListDictionary(); replacements.Add("@Name", "Ram Singh"); //now create mail message using the mail definition object //the CreateMailMessage object takes a source control object as the last parameter, //if the object you are working with is webcontrol then you can just pass "this", //otherwise create a dummy control as below. //System.Net.Mail.MailMessage msgHtml = message.CreateMailMessage(sbEmailTo.ToString(), replacements, new LiteralControl()); //AlternateView htmlView = AlternateView.CreateAlternateViewFromString(msgHtml.Body, null, "text/html"); // msg.AlternateViews.Add(htmlView); String plainEmail = "<table width='100%' border='0' cellspacing='0' cellpadding='0'><tr><td align='center'><table width='600' bgcolor='#f3f3f3' border='0' cellpadding='0' cellspacing='0'><tr><td><img src='http://localhost:4823/WishIsDone/Images/emaillogo.png' style='margin-left: 50px;'alt='' /></td></tr><tr><td><table bgcolor='#FFFFFF' border='0' width='500' align='center' style='margin: auto;
