工作学习 / 学科技术讨论 / 想写一个小程序， 功能：分析一个文本文件，提取里面的部分信息，然后自动生成email发送出去。现在不知道怎么能够“自动生成email并且发送出去”， 那位知道能否指点一下？

不是啥难事。但你这样问倒也不易解释清楚，假设你用OUTLOOK，就找点程序中如何用OUTLOOK的部件的文章吧，简单；如果啥部件都不用，就的按SMTP协议自己做个部件，没做过可能有点难度。许多开发环境都提供SMTP部件。

谢谢回答！！ 我用c#试了一下，怎么也调不通。也用了smtp类。 我希望程序越简单越好。有做过类似的吗？

两种方法: 1. 用SmtpMail 类和MailMessage类(需要设置SmtpServer ); 2.用SQL Server SendMail存储过程 (需要安装和设置Outlook)

It looks like you need credential info for authorization.Try following code to provide credential info:
SmtpClient client = new SmtpClient();
client.Host = "HOST Server IP/Name";
client.Port = Port Number;
client.Credentials = new System.Net.NetworkCredential("Uer_ID", "Pass Word", "Domain");
client.Send(...);

I don't think so. If you really doubt about .NET FW 3.5, you can switch FW to 2.0.BTW, did you configure outlook (or outlook express) in your computer to connect to yahoo mail? If not, have it done and to see if it works or not.

If you tried every thing of SmtpClient unsuccessfully, the workaround is to try Outlook automation.

这件事分成两步来做. 第一步,分析文件, 生成email所有的信息, recipient, subject, body, etc, .NET中方法有很多; 第二步, 把EMAIL发出去, 见连接. yahoo, gmail等的smtp不一定能随便用的, 反正我记得以前是用一个工具, 才能access locally.

Remove defaultCredentials="true" from configurationIf you set defaultCredentials to true and specify a user name and password, the default network credential is used, and the basic authentication data is ignored.

那就是不支持他人自行开发的发送邮件程序。一般MAIL SERVER只允许局域网内部的程序自动发送MAIL。反向思维以下，全世界千白万程序员，只要有一个人使坏，就可以是MAIL SERVER瞬间超载。

以上是大概3年前在dotnet 1.1上用c#写的，要转发也可以，直接从本机发也可以。现在有些smtp server限制的更严了，可能发不到，主要是本机ip地址的问题，不过没心情改了。可以参考一下。
