Here is the code @vishal.kp
Dim e_mail As New MailMessage()
e_mail.From = New MailAddress(" FROM Mail ID")
e_mail.[To].Add(" TO Mail ID")
'e_mail.CC.Add(" CC mail ID")
e_mail.Subject = "MAIL subject"
Dim smtp As New SmtpClient(" SMTP server you want to use")
e_mail.Body = "BODY of the mail "
smtp.Send(e_mail)
If you have any attachments to be sent in the mail, add these two lines of code
Dim fileTXT As String = "Path of the file"
Dim data As Net.Mail.Attachment = New Net.Mail.Attachment(fileTXT)
data.Name = "The name of the file you want to display in the mail"
Do remember, before using the code , you need to import the mail package
Imports System.Net.Mail
