用.net简单写个E-mail发送功能及扩展功能

//引下以下空間：
using System.Net.Mail;
//簡單實例：
//去163.com申請個帳號試試，如果有最好，呵呵
//注意using 和加入Page_Load內代碼運行一下即可發送
//public partial class SendEmail : System.Web.UI.Page
//{
protected void Page_Load(object sender, EventArgs e)
{
//发送
string strSmtp = "stmp.163.com";
string strSendEmail = "發送者郵件地址";
string strUserName = "申請人用戶名";
string strPassWord = "申請人密碼";
string strRecieveEMail = "接收者郵件地址";
string strSubject = "主題";
string strBody = "內容";
System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();
msg.To.Add(strRecieveEMail);
////附件處理
//if (txtAttachment.Text.Trim().Length > 0)
//{
// string FileName = @txtAttachment.Text.Trim();
// System.Net.Mail.Attachment pAttachment = new Attachment(FileName);
// msg.Attachments.Add(pAttachment);
//}
msg.From = new MailAddress(strSendEmail) ;

msg.Subject = strSubject;//邮件标题
msg.SubjectEncoding = System.Text.Encoding.UTF8;//邮件标题编码
msg.Body = strBody;//邮件内容
msg.BodyEncoding = System.Text.Encoding.UTF8;//邮件内容编码
msg.IsBodyHtml = false;//是否是HTML邮件
msg.Priority = MailPriority.High;//邮件优先级

SmtpClient client = new SmtpClient();
client.Host = strSmtp;//为邮件服务器设置
System.Net.NetworkCredential basicAuthenticationInfo = new System.Net.NetworkCredential(strUserName, strPassWord);
client.Credentials = basicAuthenticationInfo;

object userState = msg;
try
{
client.Send(msg);
//client.SendAsync(msg, userState);//简单一点儿可以client.Send(msg);
Response.Write("成功发送到" + strRecieveEMail + "邮箱");
}
catch (System.Net.Mail.SmtpException ex)
{
Response.Write("发送邮件出错");
throw ex;
}
}
//}


擴展：
1.郵件群發，弄一下輸入框，以“，”格開各郵件地址，使用split函數，寫一個循環便可實現。
2.郵件重發，郵件地址不變，寫一個循環，狂發，哈哈，別干惡作劇哦。

有需要此類完整代碼的，請留下E_mail。
