//设置MailMessage类的to属性所需的MailAddress
MailAddress toAddress = new MailAddress(this.tbReceiver.Text);
//设置MailMessage类的from属性所需的MailAddress
MailAddress fromAddress = new MailAddress(this.tbSender.Text);
//新建一个MailMessage类实例
MailMessage message = new MailMessage(fromAddress, toAddress);
//设置这个实例的Subject属性
message.Subject = this.tbSubject.Text;
//设置这个实例的Body属性
message.Body = this.tbMessage.Text;
//添加附件
//获得文件
HttpPostedFile postedFile = file.PostedFile;
//当有附件时
if (postedFile.ContentLength != 0)
{
//声明一个Attachment类实例
Attachment data = new Attachment(postedFile.FileName);
message.Attachments.Add(data);
}
//设置正文格式
if (rblFormat.SelectedItem.Text == "纯文本格式 ")
message.IsBodyHtml = false;
else
message.IsBodyHtml = true;
//添加抄送地址
if (this.tbCc.Text != " ")
{
MailAddress ccAddress = new MailAddress(this.tbCc.Text);
message.CC.Add(ccAddress);
}
//添加暗送地址
if (this.tbBcc.Text != " ")
{
MailAddress bccAddress = new MailAddress(this.tbBcc.Text);
message.Bcc.Add(bccAddress);
}
//新建一个SmtpClient类的实例
SmtpClient client = new SmtpClient();
//设置在本机smtp服务器中绑定的ip地址，本例为本机ip地址
client.Host = "192.168.1.103 ";
//smtp端口，默认为25
client.Port = 25;
//发送
client.Send(message);
//发送完毕后提示
Response.Write( " <script language= 'javascript '> alert( '发送成功 ') </script> ");
}
}
