Send Mail with Attachment using ASP.Net and C#.net or VB.Net

Here I am giving you the code to send mail with attachment by using ASP.Net and C#.Net or VB.Net

Use Following code to send mail with attachment.

Using C#.Net :

public int SendMessage(string subject, string messageBody, string fromAddress, string toAddress)
{
 MailMessage message = new MailMessage();
 message.IsBodyHtml = true;
 SmtpClient client = new SmtpClient();
 message.From = new MailAddress(fromAddress.ToString());
 if (toAddress.Trim().Length > 0)
 {
 foreach (string addr in toAddress.Split(';'))//you can use any delimiter
 {
 message.To.Add(new MailAddress(addr));
 }
 }
 Attachment attachFile = new Attachment("D:\\a.xls");//you can also get the file name with using fileupload control
 message.Attachments.Add(attachFile);
 message.Subject = subject;
 message.Body = messageBody;
 client.Host = "smtp address";
 client.Port = 587;//put your smtp port number
 client.UseDefaultCredentials = true;
 client.Credentials = new System.Net.NetworkCredential("mail id", "password");
 client.Send(message);
 return 1;
}

Using VB.Net :

Public Function  SendMessage(ByVal subject As String, ByVal messageBody As String, ByVal  fromAddress As String, ByVal toAddress As String) As Integer
    Dim message As MailMessage = New  MailMessage()
    message.IsBodyHtml =  True
    Dim client As SmtpClient  = New SmtpClient()
    message.From = New  MailAddress(fromAddress.ToString())
    message.To.Add(New MailAddress(toAddress.ToString()))
    Dim attachFile As Attachment = New  Attachment("D:\\a.xls") 'specify your file location
    message.Attachments.Add(attachFile)
    message.Subject = subject
    message.Body = messageBody
    client.Host = "smtp address" ' put your smtp address
    client.Port = 587 ' put your port number for smtp
    client.UseDefaultCredentials =  True
    client.Credentials = New  System.Net.NetworkCredential("smtp login  mail id", "smtp login password")
