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:
<form id="Form1" runat="server" method="post"> <div id="content"> <div id="msg"> <div id="msg_title">Send Email Test</div> <div id="msg_prompt"></div> <asp:ValidationSummary id="msg_alarm" runat="server"></asp:ValidationSummary> </div> <div id="form"> <div> <label for="SmtpServerText">Sever name:</label> <input type="text" id="SmtpServerText" name="SmtpServerText" runat="server" /> </div> <div> <label for="SmtpServerPort">Sever Port:</label> <input type="text" id="SmtpServerPort" name="SmtpServerPort" runat="server" /> </div> <div> <label for="UserName">User Name:</label> <input type="text" name="UserName" id="UserName" runat="server" /> </div> <div> <label for="Pwd">Pwd:</label> <input type="text" name="Pwd" runat="server" id="Pwd" /> </div> <div> <label for="FromAddress">From Address:</label> <input type="text" name="FromAddress" runat="server" id="FromAddress" /> </div> <div> <label for="SendAddress">Send Address:</label> <input type="text" name="SendAddress" runat="server" id="SendAddress" /> </div> <div> <label for="attachment">Attachment:</label> <input type="file" runat="server" name="attachment" id="attachment" /> </div> <div> <label for="txtSubject">Email Subject:</label> <input type="text" name="txtSubject" runat="server" id="txtSubject" /> </div> <div> <label for="txtBody">Email Body:</label> <textarea name="txtBody" runat="server" rows="10" cols="50" id="txtBody"></textarea> </div> <div> <input type="submit" value="Send Email" class="prim" id="btnSend" runat="server" onserverclick="btnSend_ServerClick" /> </div> </div> </div> </form>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)
