using System.Net.Mail;

<h2>发送邮件</h2>

  <br />收信人邮箱：<asp:TextBox runat="server" ID="textBox_mail" TextMode="Email" Columns="53" />

  <br />标题：<asp:TextBox runat="server" ID="textBox_title" Columns="60" />

  <br /><asp:CheckBox runat="server" ID="checkBox_isHtml" Text="是否HTML格式" />

  <br />内容：

  <br /><asp:TextBox runat="server" ID="textBox_content" TextMode="MultiLine" Rows="10" Columns="70" />

  <br /> <asp:Button runat="server" ID="button_send" Text="发送邮件" OnClick="button_send_Click" />

    <br />

    <asp:Literal runat="server" ID="literal_tips" />

using System;

using System.Net.Mail;

using HoverTree.HoverTreeFrame.HtNet;

using HoverTreeTop.HtConfig.MyConfig;

namespace HoverTreeTop.HoverTree.HoverTreePanel.HTPanel.HEmail

{

  public partial class EmailSend : System.Web.UI.Page

  {

    protected void Page_Load(object sender, EventArgs e)

    {

    {

      //使用smtp来发送邮件

      //literal_tips.Text = HoverTreeEmail.HoverTreeSendEmail("smtp.hovertree.com", "hello@.mail.hovertree.com",

      "hewenqi", "hello@mail.hovertree.com", "ht@mail.hovertree.com", "祝你生日快乐！", "生日快乐！天天开心！ -- 何问起");

      // literal_tips.Text = HoverTreeEmail.HoverTreeSendEmail(HtSmtpConfig.HtSmtpHost, HtSmtpConfig.HtSmtpUserName,
