This blog will explain how to create HTML Table with mutiple rows in Email body dynamically using C#.

C# Code
  1. string textBody = " <table border="+1+" cellpadding="+0+" cellspacing="+0+" width = "+400+"><tr bgcolor='#4da6ff'><td><b>Column 1</b></td> <td> <b> Column 2</b> </td></tr>";
  2. for (int loopCount = 0; loopCount < data_table.Rows.Count; loopCount++)
  3. {
  4. textBody += "<tr><td>" + data_table.Rows[loopCount]["RowName"] + "</td><td> " + data_table.Rows[loopCount]["RowName2"] + "</td> </tr>";
  5. }
  6. textBody += "</table>";
  7. MailMessage mail = new MailMessage();
  8. System.Net.Mail.SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
  10. mail.From = new MailAddress("From_Email");
  11. mail.To.Add("To_Email");
  12. mail.Subject = "Test Mail";
  13. mail.Body = textBody;
  14. mail.IsBodyHtml = true;
  15. SmtpServer.Port = 587;
  16. SmtpServer.Credentials = new System.Net.NetworkCredential("from_email", "from_email_passowrd");
  17. SmtpServer.EnableSsl = true;
  19. SmtpServer.Send(mail);
Note
  1. mail.IsBodyHtml = true;
IsBodyHTML would enable table view in the email.
We can set the table css within the code as well. Please find the snippet below.
  1. string textBody = " <table border="+1+" cellpadding="+0+" cellspacing="+0+" width = "+400+"><tr bgcolor='#4da6ff'><td><b>Column 1</b></td> <td> <b> Column 2</b> </td></tr>";
This table has a border, with cellpadding and column background color as well.

For dynamically creating rows in the table for an email, please find the below code snippet for explanation.
  1. for (int loopCount = 0; loopCount < data_table.Rows.Count; loopCount++)
  2. {
  3. textBody += "<tr><td>" + data_table.Rows[loopCount]["RowName"] + "</td><td> " + data_table.Rows[loopCount]["RowName2"] + "</td> </tr>";
  4. }
We will be looping the data table, with respect to the colum name, it will display in the specific column.
Other settings while sending email code snippet are below,
  1. mail.From = new MailAddress("from_email");
  2. mail.To.Add("To_email");
  3. mail.Subject = "Email Subject";
Mail.from - Enter from email ID
Mail.To - Enter To email ID
Mail.Subject - Subject for email.
