本文介绍如何使用.NET框架通过SMTP服务器发送电子邮件，包括设置发件人、收件人、主题和正文，以及添加附件的方法。
首先添加命名空间
Using System.Net.MailMailAddress from = new MailAddress(TBMailFrom.Text); MailAddress to = new MailAddress(TBMailTo.Text); MailMessage message = new MailMessage(from,to); message.Subject = TBSubject.Text; message.Body = TBDescript.Text; if (FileUpload1.PostedFile.FileName != "")
{
Attachment att = new Attachment(FileUpload1.PostedFile.FileName); message.Attachments.Add(att);
} SmtpClient client = new SmtpClient("smtp.163.com");smtp.Credentials = new System.Net.NetworkCredential("username", "password"); client.Send(message);我们这里在发送邮件的时候只是设置了邮件收,发件人,邮件主题和邮件正文部门,在.net里面还可以设置发送邮件的文本格式,优先级等.我们这里就不说明了,相信看看就会明白的.(message.Priority;设置优先级.mssage.Headers;设置邮件的标头. message.CC;设置抄送.message.IsBodyHtml;设置是否以html格式发送邮件)
下面是对页面的设置:
1<body>
2 <form id="form1" runat="server">
3 <div>
4 <table style="width: 268px">
5 <tr><td>
6 <asp:Label ID="Label4" runat="server" Text="发件人:"></asp:Label></td>
7 <td>
8 <asp:TextBox ID="TBMailFrom" runat="server"></asp:TextBox></td></tr>
9 <tr>
10 <td style="width: 101px">
11 <asp:Label ID="Label1" runat="server" Text=" 收件人："></asp:Label></td>
12 <td>
13 <asp:TextBox ID="TBMailTo" runat="server"></asp:TextBox></td>
14 </tr>
15 <tr>
16 <td style="width: 101px">
17 <asp:Label ID="Label2" runat="server" Text="邮件主题："></asp:Label></td>
18 <td>

20 </tr>

31 </tr>
32 <tr>

34 <asp:Button ID="BSend" runat="server" OnClick="BSend_Click" Text="发送" /></td>
35 </tr>
