我正在使用MS C#2008。我创建了Windows表单应用程序。我需要从我的应用程序发送电子邮件。那我该如何配置smtp设置呢?

EDIT

I got The following Exception

我得到以下例外

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at

SMTP服务器需要安全连接或客户端未经过身份验证。服务器响应为:5.5.1需要身份验证。了解更多信息

on smtp.send(message);

I have not installed IIS so is it required for desktop app?

我没有安装IIS,所以桌面应用程序需要它吗?

You can add the SMTP settings within the App.Config http://www.mitchelsellers.com/blogs/articletype/articleview/articleid/8/net-20-smtp-settings.aspx

您可以在App.Config中添加SMTP设置http://www.mitchelsellers.com/blogs/articletype/articleview/articleid/8/net-20-smtp-settings.aspx

And then use System.Net.Mail.SmtpClient and System.Net.Mail.MailMessage to send and create the emails.

然后使用System.Net.Mail.SmtpClient和System.Net.Mail.MailMessage发送和创建电子邮件。

c = new System.Net.Mail.SmtpClient();

msg = new System.Net.Mail.MailMessage();

System.Net.Mail.MailAddress a = new System.Net.Mail.MailAddress( sEmailAddress, sWho );

msg.To.Add( a );

msg.From = new System.Net.Mail.MailAddress("");

msg.ReplyTo = new System.Net.Mail.MailAddress("");

msg.Subject = "Web Inquiry";

msg.Body = msgBody.ToString();

c.Send( msg );

why are a lot of you that are making the "IIS" suggestions using this as the backbone to solve the problem? What if this is a deployed application? you going to have the client install and run IIS on their mediocre system just use the mail functionality of your app???

为什么有很多人正在制作“IIS”建议,以此作为解决问题的主干?如果这是部署的应用程序怎么办?你将安装客户端并在他们平庸的系统上运行IIS只需使用你的应用程序的邮件功能???

That doesn't make sense to me.

这对我来说没有意义。

Those of you looking for a solution on sending emails thru win apps, do a google search on "using gmail to send email in c#".

那些人在寻找通过赢取应用程序发送电子邮件的解决方案,在“使用gmail在c#中发送电子邮件”进行谷歌搜索。
