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 http://www.mitchelsellers.com/blogs/articletype/articleview/articleid/8/net-20-smtp-settings.aspx 中添加 SMTP 设置
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???
为什么你们中的很多人都使用它作为解决问题的主干来提出“IIS”建议？如果这是一个已部署的应用程序怎么办？你打算让客户端在他们普通的系统上安装和运行 IIS 只是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#".
那些正在寻找通过 win 应用程序发送电子邮件的解决方案的人，请在 Google 上搜索“使用 gmail 在 c# 中发送电子邮件”。
