You should try to save your file to disk before giving it to the SmtpClient class.
1. you can make sure your file is actually not empty before you send
2. when sending the fule it is most likely that the HttpResponse (container for your input stream) has been disposed already.

I would change the this line:

message.Attachments.Add(new Attachment(uploadedfile.InputStream,uploadedfile.FileName));

to this:

message.Attachments.Add(new MailAttachment(uploadedfile.FileName));

See what that gets you.

You need to create the object of Attachment Class. The object of Attachment class can be added to MailMessage Class. Try this:

C#

SmtpClient smtpClient = null;
MailMessage smtpMail = null;
Attachment attachment = null;
try
{
    smtpMail = new MailMessage(From, To);
    smtpMail.Subject = Subject;
    smtpMail.Body = Body;
    smtpMail.IsBodyHtml = IsBodyHTML;
    attachment = new Attachment(file.Trim()); //file : Absolute path of your file
    smtpMail.Attachments.Add(attachment); // Adding attachment "System.Net.Mail"
    smtpClient = new SmtpClient();
    smtpClient.Host = "MailSettings-Host"; //Here you need to pass the host address
    smtpClient.Port = "MailSettings-Port"; //Here you need to pass the host port
    smtpClient.UseDefaultCredentials = true;
    smtpClient.Send(smtpMail);
    Response.Write("Mail sent!!");
}
catch (Exception ex)
{
    Response.Write(ex.Message);
}
finally
{
    attachment = null;
    smtpClient = null;
    smtpMail = null;
}

I have created a folder where my attachment will be saved. so that now the path of the file is easily get by Server.MapPath("filepath") function and then the attachment easily send to client. after sending the file it will be deleted from the folder using File.Delete(filepath) function.
