email body coming in a single line

I am sending emails thorugh c#. The body of the mail is dynamic i.e. user fills it in before sending the mail. Issue is the body text is coming in a single line instead of multiple lines as they should.
using (MailMessage mm = new MailMessage(txtEmail.Text.Trim(), email.Trim()))
{
try
{
mm.CC.Add(txtcc.Text.Trim());
mm.Subject = txtSubject.Text.Trim();
mm.Body = txtBody.Text;
MemoryStream pdf = new MemoryStream(bytes);
mm.Attachments.Add(new Attachment(pdf, "Report.pdf"));
mm.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
NetworkCredential credentials = new NetworkCredential();
credentials.UserName = txtEmail.Text.Trim();
credentials.Password = txtPassword.Text.Trim();
smtp.UseDefaultCredentials = true;
smtp.Credentials = credentials;
smtp.Port = 587;
smtp.Send(mm);
}
catch (Exception ex)
{
Alert.show1("Could not send the e-mail - error: " + ex.Message, this);
return;
}
}

If you dont need the potential of HTML formatting, you could avoid the problem changing the email format to plain text. This could also avoid user entering text that could be parsed as html.
mm.IsBodyHtml = false;
Otherwise you should change the end line character to html breaking line:
mm.IsBodyHtml = true;
mm.Body = mm.Body.Replace(#"\n", "<br />");
In case of the html format option, It would be wise to follow Fildor's comment and add an alternateView in plain text for email clients that are not html capable.

Error on sending email from C# code

When I send mail to my gmail account, it shows below error.
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.1 Authentication required...
code I am using is below
MailMessage m = new MailMessage();
SmtpClient sc = new SmtpClient();
try
{
m.From = new MailAddress("me#gmail.com");
m.To.Add("me#gmail.com");
m.Subject = "This is a Test Mail";
m.IsBodyHtml = true;
m.Body = "test gmail";
sc.Host = "smtp.gmail.com";
sc.Port = 587;
sc.Credentials = new System.Net.NetworkCredential("me#gmail.com", "passward");
sc.UseDefaultCredentials = true;
sc.EnableSsl = true;
sc.Send(m);
Response.Write("Email Send successfully");
}
catch (Exception ex)
{
Response.Write(ex.Message);
}

Just tried your code, had to fiddle with a couple things but was sent this. Funny because I have done this previously using Gmail smtp (couple years back). But it looks like they are now verifying apps that use their platform.
Either use another smtp server that you are signed up to, or use your own. (there must be a test one that is available online??). Pretty sure sendgrid do a free trial.

using System.Net;
using System.Net.Mail;
string smtpAddress = "smtp.mail.yahoo.com";
int portNumber = 587;
bool enableSSL = true;
string emailFrom = "email#yahoo.com";
string password = "abcdefg";
string emailTo = "someone#domain.com";
string subject = "Hello";
string body = "Hello, I'm just writing this to say Hi!";
using (MailMessage mail = new MailMessage())
{
mail.From = new MailAddress(emailFrom);
mail.To.Add(emailTo);
mail.Subject = subject;
mail.Body = body;
mail.IsBodyHtml = true;
// Can set to false, if you are sending pure text.
mail.Attachments.Add(new Attachment("C:\\SomeFile.txt"));
mail.Attachments.Add(new Attachment("C:\\SomeZip.zip"));
using (SmtpClient smtp = new SmtpClient(smtpAddress, portNumber))
{
smtp.Credentials = new NetworkCredential(emailFrom, password);
smtp.EnableSsl = enableSSL;
smtp.Send(mail);
}
}
Please try this this should work for you
Thank you

How to add Parameters into HTML Template where i am getting all the parameters of that in the same page in Textboxes. Please help me out

I think you already discovered the answer yourself, but I will keep posting the answer instead.
In case you are using Windows Forms and not Windows Presentation Forms (The different only the design part and many new features that does not have on Windows Forms), what I have done is like this (to send email):
public void SendEmail(string _from, string _fromDisplayName, string _to, string _toDisplayName, string _subject, string _body, string _password)
{
try
{
SmtpClient _smtp = new SmtpClient();
MailMessage _message = new MailMessage();
_message.From = new MailAddress(_from, _fromDisplayName); // Your email address and your full name
_message.To.Add(new MailAddress(_to, _toDisplayName)); // The recipient email address and the recipient full name // Cannot be edited
_message.Subject = _subject; // The subject of the email
_message.Body = _body; // The body of the email
_smtp.Port = 587; // Google mail port
_smtp.Host = "smtp.gmail.com"; // Google mail address
_smtp.EnableSsl = true;
_smtp.UseDefaultCredentials = false;
_smtp.Credentials = new NetworkCredential(_from, _password); // Login the gmail using your email address and password
_smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
_smtp.Send(_message);
ShowMessageBox("Your message has been successfully sent.", "Success", 2);
}
catch (Exception ex)
{
ShowMessageBox("Message : " + ex.Message + "\n\nEither your e-mail or password incorrect. (Are you using Gmail account?)", "Error", 1);
}
}
And I am using it like this:
SendEmail(textBox2.Text, textBox5.Text, textBox3.Text, "YOUR_FULL_NAME", textBox4.Text, textBox6.Text, "YOUR_EMAIL_PASSWORD");
Here is the image:
May this answer would help you.
Cheers!

Is there anyway to display Right To Left plain text mails?

I'm sending mails in c# using SmtpClient.
i'm sending the mails as plain text:
message.IsBodyHtml =False;
how can I send them as RTL? with HTML mails it's very easy-just tag them as RTL.
Sample code:
public void SendEmail(bool isJapanese)
{
try
{
MailAddress from = new MailAddress(FromEmail,FromDisplay);
MailAddress to = new MailAddress(ToEmail, ToDisplay);
MailMessage message = new MailMessage( from, to);
message.Subject = Subject;
if (!IsHTML)
Body = Body.Replace("<br/>", "\r\n").Replace("<br/>", "\r").Replace("<br/>", "\n");
message.Body =Body;
message.BodyEncoding = Encoding.UTF8;
message.SubjectEncoding = Encoding.UTF8;
message.IsBodyHtml = IsHTML;
smtpClient.Send(message);
}
catch (Exception ex)
{
ex.HelpLink += "class MailSender, fn SendMail(); ";
Log(ex);
}
}

there is no way to indeciate alignment of plain text mails.
by the way- Gmail is autodetcting RTL languages but this is the only provider i see that doe's that.

Send HTML email via C# with SmtpClient

How do I send an HTML email? I use the code in this answer to send emails with SmtpClient, but they're always plain text, so the link in the example message below is not formatted as such.
<p>Welcome to SiteName. To activate your account, visit this URL:
http://SiteName.com/a?key=1234.
</p>
How do I enable HTML in the e-mail messages I send?

This is what I do:
MailMessage mail = new MailMessage(from, to, subject, message);
mail.IsBodyHtml = true;
SmtpClient client = new SmtpClient("localhost");
client.Send(mail);
Note that I set the mail message html to true: mail.IsBodyHtml = true;

I believe it was something like:
mailObject.IsBodyHtml = true;

IsBodyHtml = true is undoubtedly the most important part.
But if you want to provide an email with both a text/plain part and a text/html part composed as alternates, it is also possible using the AlternateView class:
MailMessage msg = new MailMessage();
AlternateView plainView = AlternateView
.CreateAlternateViewFromString("Some plaintext", Encoding.UTF8, "text/plain");
// We have something to show in real old mail clients.
msg.AlternateViews.Add(plainView);
string htmlText = "The <b>fancy</b> part.";
AlternateView htmlView =
AlternateView.CreateAlternateViewFromString(htmlText, Encoding.UTF8, "text/html");
msg.AlternateViews.Add(htmlView); // And a html attachment to make sure.
msg.Body = htmlText; // But the basis is the html body
msg.IsBodyHtml = true; // But the basis is the html body

Apply the correct encoding of the Mailbody.
mail.IsBodyHtml = true;

i have an idea , you can add a check box to your project for sending email as html as an option for user , and add this code to enable it :
MailMessage mail = new MailMessage(from, to, subject, message);
if(checkBox1.CheckState == CheckState.Checked )
{
mail.IsBodyHtml = true;
}
SmtpClient client = new SmtpClient("localhost");
client.Send(mail);

If you are using Mailkit,We can use TextBody,HtmlBody and Both for message body. Just write this code. It will help you
MimeMessage mailMessage = new MimeMessage();
mailMessage.From.Add(new MailboxAddress(senderName, sender#address.com));
mailMessage.Sender = new MailboxAddress(senderName, sender#address.com);
mailMessage.To.Add(new MailboxAddress(emailid, emailid));
mailMessage.Subject = subject;
mailMessage.ReplyTo.Add(new MailboxAddress(replyToAddress));
mailMessage.Subject = subject;
var builder = new BodyBuilder();
builder.HtmlBody = "Hello There";
mailMessage.Body = builder.ToMessageBody();
try
{
using (var smtpClient = new SmtpClient())
{
smtpClient.Connect("HostName", "Port", MailKit.Security.SecureSocketOptions.None);
smtpClient.Authenticate("user#name.com", "password");
smtpClient.Send(mailMessage);
Console.WriteLine("Success");
}
}
catch (SmtpCommandException ex)
{
Console.WriteLine(ex.ToString());
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
