プレーンテキストまたはhtmlテンプレートのいずれかの代替ビューで電子メールを送信したいのですが、次のリンク aspnet-sending-email-both-in-html-and-plain-textのコードを使用しましたが、なぜそれが機能しないのかわかりません..私のコードは：。
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("visionstask@gmail.com");
msg.Subject = "Event: testing";
msg.To.Add("ram@tsgdev.net");
// create a string to hold all email addresses
StringBuilder sbEmailTo = new StringBuilder();
sbEmailTo.Append("visionstask@gmail.com");
//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 = "visionstask@gmail.com";
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; border: 1px solid #999; padding: 5px;' cellpadding='0' cellpadding='0'><tr><td style='font-size: 18px; font-family: Verdana, Geneva, sans-serif; color: #008fbb;'>Registration</td></tr></table></td></tr><tr><td><table bgcolor='#FFFFFF' border='0' width='500' align='center' style='margin: auto; border: 1px solid #999; padding: 20px;'><tr><td>Hello @Name!</td></tr><tr><td style='font-size: 11px; font-family: Verdana, Geneva, sans-serif;'>Welcome to WishIsDone Website </td></tr><tr><td style='font-size: 12px; color: #008fbb; font-family: Verdana, Geneva, sans-serif;'> <p>You have successfully registrated.</p> </td> </tr><tr><td style='font-size: 11px; font-family: Verdana, Geneva, sans-serif; color: #999;'><p>Verify your e-mail address to complete your registration by clicking the link:</p> <p><a href='#'>@link</a></p><p><strong style='color: #000; font-size: 10px; font-weight: bold;'>Note:</strong><span style='color: #333;'>please change your password after login.</span></p><table style='border-top: 1px dotted #999; margin: auto;' width='450'><tr><td style='font-size: 10px; color: #333;'><p>Regards,<br /> Wish Is Done Team</p></td></tr></table></td></tr> </table> </td></tr> <tr> <td style='font-size: 10px; color: #333; padding: 10px 50px; font-family: Verdana, Geneva, sans-serif;'> <p> For any queries or difficulties Contact:<br /> Email:<a href='#'>info@wishisdone.com</a><br /> Toll free: XXX-XXX-XXXX<br /> <a href='#'>www.wishisdone.com</a></p> </td></tr><tr><td><table style='border-top: 1px dotted #999; width: 500px; color: #333; margin: auto; font-size: 9px; font-family: Verdana, Geneva, sans-serif;'> <tr><td>Copyright © 2012 wishisdone</td></tr></table></td></tr></table></td> </tr></table>";
//first we create the Plain Text part
AlternateView plainView = AlternateView.CreateAlternateViewFromString(plainEmail, null, "text/plain");
msg.AlternateViews.Add(plainView);
msg.IsBodyHtml = true;
SmtpClient emailClient = new SmtpClient("smtp.gmail.com");
System.Net.NetworkCredential SMTPUserInfo = new System.Net.NetworkCredential("test@gmail.com", "test");
emailClient.UseDefaultCredentials = false;
emailClient.Credentials = SMTPUserInfo;
emailClient.Port = 587;
emailClient.EnableSsl = true;
//SmtpClient emailClient = new SmtpClient(ConfigurationManager.AppSettings["SMTP"].ToString());
//emailClient.UseDefaultCredentials = false;
//emailClient.EnableSsl = true;
emailClient.Send(msg);
}
そして私はメールで次のアウトアウトを受け取っています：
<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; border: 1px solid #999; padding: 5px;' cellpadding='0' cellpadding='0'><tr><td style='font-size: 18px; font-family: Verdana, Geneva, sans-serif; color: #008fbb;'>Registration</td></tr></table></td></tr><tr><td><table bgcolor='#FFFFFF' border='0' width='500' align='center' style='margin: auto; border: 1px solid #999; padding: 20px;'><tr><td>Hello @Name!</td></tr><tr><td style='font-size: 11px; font-family: Verdana, Geneva, sans-serif;'>Welcome to WishIsDone Website </td></tr><tr><td style='font-size: 12px; color: #008fbb; font-family: Verdana, Geneva, sans-serif;'> <p>You have successfully registrated.</p> </td> </tr><tr><td style='font-size: 11px; font-family: Verdana, Geneva, sans-serif; color: #999;'><p>Verify your e-mail address to complete your registration by clicking the link:</p> <p><a href='#'>@link</a></p><p><strong style='color: #000; font-size: 10px; font-weight: bold;'>Note:</strong><span style='color: #333;'>please change your password after login.</span></p><table style='border-top: 1px dotted #999; margin: auto;' width='450'><tr><td style='font-size: 10px; color: #333;'><p>Regards,<br /> Wish Is Done Team</p></td></tr></table></td></tr> </table> </td></tr> <tr> <td style='font-size: 10px; color: #333; padding: 10px 50px; font-family: Verdana, Geneva, sans-serif;'> <p> For any queries or difficulties Contact:<br /> Email:<a href='#'>info@wishisdone.com</a><br /> Toll free: XXX-XXX-XXXX<br /> <a href='#'>www.wishisdone.com</a></p> </td></tr><tr><td><table style='border-top: 1px dotted #999; width: 500px; color: #333; margin: auto; font-size: 9px; font-family: Verdana, Geneva, sans-serif;'> <tr><td>Copyright © 2012 wishisdone</td></tr></table></td></tr></table></td> </tr></table>
私を助けてください..私はそれを適切にフォーマットされた方法で表示したいので、私は別のビューを使用したいと思います。
