asp.net 2.0发送和接收邮件总结

总结:.用asp.net 2.0发送邮件非常的方便,只需要用using System.Net.Mail命名空间下的类就可以完成发送邮件的功能,发送邮件的服务器可以有以下几种情况:
1.本地的smtp服务器
2.网络上的smtp服务器(smtp.163.com等)
以下是我测试发送邮件的范例,基本上都考虑到的所有的情况,如果还有什么没有考虑到的请给我留言,我接续完善其功能.
1.新建一网站名字叫SentEmailText.
2.添加一个新的页面default.aspx
代码如下:

<formid="Form1"runat="server"method="post">
<divid="content">
<divid="msg">
<divid="msg_title">SendEmailTest</div>
<divid="msg_prompt"></div>
<asp:ValidationSummaryid="msg_alarm"runat="server"></asp:ValidationSummary>
</div>
<divid="form">
<div>
<labelfor="SmtpServerText">Severname:</label>
<inputtype="text"id="SmtpServerText"name="SmtpServerText"runat="server"/>
</div>
<div>
<labelfor="SmtpServerPort">SeverPort:</label>
<inputtype="text"id="SmtpServerPort"name="SmtpServerPort"runat="server"/>
</div>
<div>
<labelfor="UserName">UserName:</label>
<inputtype="text"name="UserName"id="UserName"runat="server"/>
</div>
<div>
<labelfor="Pwd">Pwd:</label>
<inputtype="text"name="Pwd"runat="server"id="Pwd"/>
</div>
<div>
<labelfor="FromAddress">FromAddress:</label>
<inputtype="text"name="FromAddress"runat="server"id="FromAddress"/>
</div>
<div>
<labelfor="SendAddress">SendAddress:</label>
<inputtype="text"name="SendAddress"runat="server"id="SendAddress"/>
</div>
<div>
<labelfor="attachment">Attachment:</label>
<inputtype="file"runat="server"name="attachment"id="attachment"/>
</div>
<div>
<labelfor="txtSubject">EmailSubject:</label>
<inputtype="text"name="txtSubject"runat="server"id="txtSubject"/>
</div>
<div>
<labelfor="txtBody">EmailBody:</label>
<textareaname="txtBody"runat="server"rows="10"cols="50"id="txtBody"></textarea>
</div>
<div>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<inputtype="submit"value="SendEmail"class="prim"id="btnSend"runat="server"onserverclick="btnSend_ServerClick"/>
</div>
</div>
</div>
</form>

3.新建一个style的文件夹,添加样式页面,主要功能是表单的对齐样式,比较通用的设置(见附件)
4.添加一个mail的类文件,注意用于发送邮件考虑的几种情况(见附件)
