pls advice me

Hi, you can do it using System.Linq:

var directory = new DirectoryInfo(Server.MapPath("/files/"));
var myFile = (from f in directory.GetFiles()
                  where f.Name.EndsWith(".cst") 
                  orderby f.LastWriteTime descending
                  select f).FirstOrDefault();


var email = new EmailMessage()
        {
            ...
        };

        email.Attachments.Add(new System.Net.Mail.Attachment(Server.MapPath(myFile.Name)));
        // Send e-mail
        EmailSender.SendEmail(email);

Hi Dawid! Thanks for your help. var directory = new DirectoryInfo(Server.MapPath("/files/")); in this line I Enter "C:/inetpub/uploadFiles/" as the path of the directory which is a server location. but if i tried to if (directory.Exists) it returns false (folder is not there)

Thank you! Ramesh
