Code :

try {
StreamReader sr=new StreamReader("MyContent.htm");
sr = File.OpenText("MyContent.htm");
string result = sr.ReadToEnd(); sr.Close();
}
catch(Exception ex) {
Response.Write(ex.Message); return;
}
string MessageBody=result.Replace("<YourFriendName>", txtFriendName.Text); MessageBody=MessageBody.Replace("<YourName>", txtMyName.Text); MessageBody= MessageBody.Replace("<DateYouSendThisEmail>",
DateTime.Today.ToString());
MailMessage mail = new MailMessage();
mail.Body = MessageBody;
mail.BodyFormat = MailFormat.Html;
mail.From = "YOUR EMAIL ID";
mail.To = "YOUR FRIEND'S EMAIL ID";
mail.Subject = "Dynamic Content Email From "+ txtMyName.Text; SmtpMail.SmtpServer = "your email server"; SmtpMail.Send(mail);
