{
string myMaillAdress = "";
string myMaillPassword = "";
string myMaillMessage = "";
string toMaillAdress = "";
QQEmail qq_mial = new QQEmail();
bool send_status = qq_mial.IsSendEmail(myMaillAdress, toMaillAdress, myMaillMessage, myMaillPassword);
}
class QQEmail
{
public bool IsSendEmail(string FromAddress, string ToAddress, string Message, string Pwd)
{
MailAddress Address = new MailAddress(FromAddress);
MailMessage mail = new MailMessage();
mail.SubjectEncoding = System.Text.Encoding.UTF8;
