asp.net利用Jmail发送邮件和接收全部代码

利用Jmail发送邮件:

private void SendMailByJmail()

{

/**////建立发邮件类

jmail.MessageClass oJmailMessage = new jmail.MessageClass();

/**//// 字符集

oJmailMessage.Charset = "GB2312";

/**////附件的编码格式

/**////是否将信头编码成iso-8859-1字符集

oJmailMessage.ISOEncodeHeaders = false;

/**//// 优先级

oJmailMessage.Priority = Convert.ToByte(1);

/**////发送人邮件地址

oJmailMessage.From = TxtEmail.Text.Trim();

/**////发送人姓名

oJmailMessage.FromName = TxtName.Text.Trim();

/**//// 邮件主题

oJmailMessage.Subject = txtSubject.Text.Trim();

/**////身份验证的用户名

oJmailMessage.MailServerUserName = TxtSmtpUser.Text.Trim();

/**////用户密码

oJmailMessage.MailServerPassWord = TxtSmtpPwd.Text.Trim();

/**////添加一个收件人，抄送人和密送人的添加和该方法是一样的，只是分别使用AddRecipientCC和RecipientBCC两个属性

///要是需要添加多个收件人，则重复下面的语句即可。添加多个抄送和密送人的方法一样

oJmailMessage.AddRecipient(txtReciver.Text.Trim(),"","");

if("" != upFile.PostedFile.FileName)

{

string attpath = upFile.PostedFile.FileName;

oJmailMessage.AddAttachment(@attpath,true,attpath.Substring(attpath.LastIndexOf(".")+1,3));//添加附件

}

/**////邮件内容

oJmailMessage.Body = txtContent.Text.Trim();
