发送Email并添加附件
1. 添加命名空间
using System.Net.Mail;using System.Net;
2. The HTML MarpUp
<html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title></head><body> <form id="form1" runat="server"> <div> <table> <tr> <td> <asp:Label ID="Label1" runat="server" Text="From:"></asp:Label> </td> <td> <asp:TextBox ID="txtFrom" runat="server" Height="17px" Width="231px"></asp:TextBox> </td> </tr> <tr> <td> <asp:Label ID="Label3" runat="server" Text="To:"></asp:Label> </td> <td> <asp:TextBox ID="txtTo" runat="server" Height="19px" Width="226px"></asp:TextBox> </td> </tr> <tr> <td> <asp:Label ID="Label2" runat="server" Text="Subject:"></asp:Label> </td> <td> <asp:TextBox ID="txtSubject" runat="server" Height="19px" Width="240px"></asp:TextBox> </td> </tr> <tr> <td> <asp:Label ID="Label4" runat="server" Text="Body:"></asp:Label> </td> <td> <asp:TextBox ID="txtBody" runat="server" TextMode="MultiLine" Height="102px" Width="234px"></asp:TextBox> </td> </tr> <tr> <td> <asp:Label ID="Label5" runat="server" Text="Accachment:"></asp:Label> </td> <td> <asp:FileUpload ID="FileUpload1" runat="server" /> </td> </tr> <tr> <td colspan="2" style="text-align:center"> <asp:Button ID="Button1" runat="server" Text="Send" OnClick="Button1_Click" /> </td> </tr> </table> </div> </form></body></html>
3. 封装了一个发送Email的方法,根据此方法添加相应的参数，即可进行发功邮件
protected void SendMail(string FromAddress, string ToAddress, string Subject, string Body, string UserName, string Password) { // smtp settings SmtpClient smtp = new SmtpClient(); { smtp.Host = "smtp.gmail.com"; smtp.Port = 587; smtp.EnableSsl = true; smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; smtp.Credentials = new NetworkCredential(UserName, Password); smtp.Timeout = 20000; } //mail settings MailMessage mail = null; if (FileUpload1.HasFile) { mail = new MailMessage(FromAddress, ToAddress, Subject, Body); //add attachment file String FileName = FileUpload1.PostedFile.FileName; System.Net.Mail.Attachment attachment; attachment = new System.Net.Mail.Attachment(FileName); mail.Attachments.Add(attachment); } smtp.Send(mail); }
