附加文件..

Attaching document..

using System.IO;
using System.Net;
using System.Net.Mail;
using System.Text;
using System.Globalization;

string to = "[e-mail]";//To address
string from = "[e-mail]";//From address
MailMessage message = new MailMessage(from, to);

if (fuAttachment.HasFile)//Attaching document 
        {
            string FileName = Path.GetFileName(fuAttachment.PostedFile.FileName);
            message .Attachments.Add(new Attachment(fuAttachment.PostedFile.InputStream, FileName));
        }
message.Subject = txt_subject.text;
message.Body = mailbody;
message.BodyEncoding = Encoding.UTF8;
message.IsBodyHtml = true;
SmtpClient client = new SmtpClient("smtp.gmail.com", 587);
System.Net.NetworkCredential basicCredential1 = new
System.Net.NetworkCredential("yourmail id", "Password");
