NET实现发送邮件

1.以QQ邮箱为例，首先打开QQ邮箱设置的账户，将对应的服务启动。

　

2.前台如下：

 1 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Start.aspx.cs" Inherits="Tset.Start" %>
 2 
 3 <!DOCTYPE html>
 4 
 5 <html xmlns="http://www.w3.org/1999/xhtml">
 6 <head runat="server">
 7 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
 8     <title></title>
 9 </head>
10 <body>
11     <form id="form1" runat="server">
12     <div>
13         <asp:Button ID="btnStart" runat="server" Text="发送" OnClick="btnStart_Click" />
14         <asp:Label ID="labInfo" runat="server"  Visible="False" ForeColor="#FF0066"></asp:Label>
15     </div>
16     </form>
