发送邮件的问题

Question

我编写了个发送邮件的程序:发送时出现如下错误:
发送失败:System.Web.HttpException: 未能访问“CDO.Message”对象
请问是怎么回事.

Answer 1

/创建MailMessage对象
MailMessage MyMsg = new MailMessage();
MyMsg.From = tbFrom.Text;
MyMsg.To = tbTo.Text;
MyMsg.Subject = tbSubject.Text;
MyMsg.Priority = (MailPriority)ddlPriority.SelectedIndex;
MyMsg.BodyFormat= (MailFormat)ddlBodyFormat.SelectedIndex;
MyMsg.Body = tbBody.Text;
MyMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");  MyMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername","[email protected]");  MyMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "53344521binbin");

//如果有附件则上传
HttpPostedFile hpfFile = AttachFile.PostedFile;
if(hpfFile.FileName!="")
{
//有附件，则上传到Temp目录中
//取得文件名(不含路径)
char[] de = {'\\'};
string[] AFilename  = hpfFile.FileName.Split(de);
string strFilename  = AFilename[AFilename.Length-1];
string strPath = Server.MapPath(".")+"\\Temp\\"+strFilename;
hpfFile.SaveAs(strPath);
//添加附件
MyMsg.Attachments.Add(new MailAttachment(strPath));
} try
{
//发送
SmtpMail.Send(MyMsg);
lblShowMsg.Text ="发送成功";
tbTo.Text = "";
tbSubject.Text = "";
tbBody.Text = "";
ddlPriority.SelectedIndex = 1;
ddlBodyFormat.SelectedIndex = 0;
}
catch(Exception ee)
{
lblShowMsg.Text = "发送失败:"+ee.ToString();
}
}
