.net 2.0 中发送Email

在 .net 2.0 中发送邮件将使用到新增的 SmtpClient 类，并且可以在配置文件中加入 mailSettings 元素来配置 smtp。下面以 asp.net 为例写的 demo.

在 web.config 文件添加

<system.net>
<mailSettings>
<smtp>
<network host="localhost" port="25" userName="your username"
password="your password"/>
</smtp>
</mailSettings>
</system.net>

发送简单的文本格式的邮件

<script runat="server">
protected void SendEmail_Click (object sender, EventArgs e)
{
MailMessage mm = new MailMessage (tbxUsersEmail.Text,
tbxUsersEmail.Text);

mm.Subject = tbxSubject.Text;
mm.Body = tbxBody.Text;
mm.IsBodyHtml = false;

SmtpClient smtp = new SmtpClient ();

smtp.Send (mm);
Response.Write ("Completed!");
}
</script>
