推荐答案

您可以使用的 SmtpClient 类：

foreach (DataRow row in datatable.Rows)
{
    var name = (string)row["Name"];
    var email = (string)row["MailID"];
    var body = (string)row["Body"];

    var message = new MailMessage();
    message.To.Add(email);
    message.Subject = "This is the Subject";
    message.From = new MailAddress("[e-mail]");
    message.Body = body;
    var smtpClient = new SmtpClient("yoursmtphost");
    smtpClient.Send(message);
}

备注1：在.NET 4.0中， SmtpClient 工具 IDisposable的的，所以一定要正确处理它。

Remark1: In .NET 4.0, SmtpClient implements IDisposable, so make sure to properly dispose it.

备注2：有一个<一个href="http://www.google.com/#hl=en&source=hp&q=smtpclient+quit&aq=f&aqi=g1&aql=&oq=&gs_rfai=&fp=8631cdd35a4d476d"相对=nofollow>错误，在 SmtpClient 类之前，.NET 4.0不正确地发送退出命令到SMTP服务器。

Remark2: There's a bug in SmtpClient class prior to .NET 4.0 which doesn't properly send the QUIT command to the SMTP server.
