2.实现用户注册时，向其油箱发送激活码邮件，并进行状态处理。
注册页面：
<body>
<form id="form1" runat="server">
<div>
<table style="width:100%;">
<tr>
<td>
用户名：</td>
<td>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
密码：</td>
<td>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
邮箱：</td>
<td>
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
</td>
<td>
<asp:Button ID="Button1" runat="server" Xonclick="Button1_Click" Text="注册" />
</td>
</tr>
</table>

</form>
</body>
