message from an application very easily";

MailMessage message = new
MailMessage();

//可以利用MailMessageToAdd方法增加要发送的邮件地址

message To Add (new MailAddress ("652105072@qqcom"));

MailAddress(_to));

messageSubject = _subject;

messageBody = _body;

//添加附件

Attachment a = new
Attachment(@"C:/Users/Administrator/Desktop/smtpclientrar");

messageAttachmentsAdd(a);

//设置邮箱的地址或IP

SmtpClient client = new
SmtpClient(server);

//设置邮箱端口，pop3端口:110, smtp端口是:25

clientPort = 25;

//设置超时时间

clientTimeout = 9999;

//要输入邮箱用户名与密码

clientCredentials = new NetworkCredential("young-20@163com", "");

clientSend(message);

}

catch (Exception ex)

{

Success = exToString();

}

return Success;
