我不明白什么问题? [英] what is the problem ı dont understand?

问题描述

我编写了一个用于发送邮件的共享点Web部件

我对Windows窗体应用程序使用相同的代码，Windows窗体应用程序发送邮件，但是sharepoint Web部件给我一个错误

低于此错误

I write a sharepoint web part for sending mail

I use same code for windows form application windows form application sending mail but sharepoint web part gives me a error

Below this error

Server Error in '/' Application.
The remote name could not be resolved: 'smtp host name'

下面的代码

code below

MailAddress ma = new MailAddress("mailadresss", "Admin");

           MailMessage posta = new MailMessage();
           posta.Body = TextBox2.Text;
           posta.Subject = TextBox1.Text;
           posta.To.Add(Label2.Text);
           posta.From = ma;
           posta.Priority = System.Net.Mail.MailPriority.High;

           SmtpClient smtp = new SmtpClient();
           smtp.Credentials = new System.Net.NetworkCredential("mailadress", "password");
           smtp.Port = 25;
           smtp.Host = "smtp host name";
           smtp.Send(posta);

我无法理解相同的代码，但会给出错误

I don''t understand same code but givess error

推荐答案

这里可能发生了几件事.我建议的第一件事是使用异常处理来查找实际错误.或查看ULS日志以跟踪问题.确保服务器之间的通信没有中断.如果没有其他规定，SharePoint具有自己的发送电子邮件的机制， SPUtility.SendEmail [ ^ ]

There could be a couple of things happening here. The first thing I would suggest is to use exception handling to find the actual error. Or look at the ULS logs to trace the problem. Make sure the communication between the servers is not being disrupted. If all else, SharePoint has its own mechanism for sending email, SPUtility.SendEmail[^]

您需要将"smtp主机名"更改为有效的SMTP主机名(SMTP服务器).

祝你好运！

You need to change ''smtp host name'' to a valid SMTP host name (SMTP server).

Good luck!
