问题描述

有人可以提供有关如何为System.Net.Mail(针对VB)编码的明确答案吗?

我正在尝试解决"System.IO.IOException无法读取数据"的问题来自运输连接最近的服务器更新后出现的问题.该代码运行良好，直到前一天更新失败.

这是曾经起作用的代码:

Can someone provide a difinitive answer for how to code for System.Net.Mail (for VB)?

I'm tryng to resolve the "System.IO.IOException Unable to read data from the transport connection " that cropped up after a recent Server update. The code was working fine until an update came down the other day.

This is the code that used to work:

Dim MailClient As New SmtpClient(My.Settings.Server, My.Settings.Port)

MailClient.Credentials = New NetworkCredential(My.Settings.UserName, My.Settings.Password, My.Settings.Domain)

Dim ToAddr As String = Me.txtTo.Text.Replace(";", ",")

Dim CCAddr As String = Me.txtCC.Text.Replace(";", ",")

Dim msg As New MailMessage(Me.txtFrom.Text, ToAddr)<br/><span style="font-size:x-small"><p>MailClient.Send(msg)</p></span><br/>

推荐答案

第一组代码正确，我想通知您这不是程序错误.这是邮件服务器的DNS错误，如果您落后于ISP，例如{comcast，att，roadrunner等}，这就是您的问题.不要灰心，您只需要提高自己的网络技能和交流技能即可.如果这不是DNS问题，也可能是由于中继设置不正确引起的.谢谢查理

The first set of code is correct and I would like to notify you that this is not a programmatic error.  This is a DNS error with your mail server and if you behind an ISP like {comcast, att, road runner, and etc} this is your problem.  Don't be discouraged you just need to brush up on your networking skills along with exchange skills. If this is not a DNS issue it could also be caused by incorrect relay settings. Thanks Charlie
