asp.net 郵件發送提醒功能（接收方包括QQ郵箱等） · asp.net 應用開發

?? 1、編寫一個通用的郵件發送操作類：MailHelper.cs,代碼如下： ~~~ using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mail; /// <summary> ///MailHelper 的摘要說明 /// </summary> public class MailHelper { public MailHelper() { // //TODO: 在此處添加構造函數邏輯 // } /// <summary> /// 郵件發送操作 /// </summary> /// <param name="Addressee">收件人地址</param> /// <param name="From">發件人地址</param> /// <param name="sendpassword">發件人密碼</param> /// <param name="Copy">抄送人地址</param> /// <param name="secret">密送人地址</param> /// <param name="Subject">發送主題</param> /// <param name="Attachment">附件信息</param> /// <param name="Body">郵件內容</param> public string SendeEmail(string Addressee, string From, string sendpassword, string Copy, string secret, string Subject, string Attachment, string Body) { MailMessage objMailMessage; MailAttachment objMailAttachment; // 創建郵件消息 objMailMessage = new MailMessage(); //發件人EMAIL objMailMessage.From = From;//源郵件地址 //收件人EMAIL objMailMessage.To = Addressee; //目的郵件地址 //郵件抄送 objMailMessage.Cc = Copy; //郵件misong objMailMessage.Bcc = secret; //郵件主題 objMailMessage.Subject = Subject; //發送郵件的標題 //郵件內容 objMailMessage.Body = Body;//發送郵件的內容 // 創建一個附件對象 if (Attachment != "") { objMailAttachment = new MailAttachment(Attachment);//發送郵件的附件 c:\\test.txt objMailMessage.Attachments.Add(objMailAttachment);//將附件附加到郵件消息對象中 } //接著利用SMTP來發送郵件，需要使用Microsoft .NET Framework SDK v1.1和它以上的版本 //基本權限 objMailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1"); //用戶名 string name = From.Substring(0, From.IndexOf('@')); objMailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", name); //密碼 objMailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", sendpassword); //如果沒有上述三行代碼，則出現如下錯誤提示：服務器拒絕了一個或多個收件人地址。服務器響應為: 554 : Client host rejected: Access denied //SMTP地址 string smtp = "smtp." + From.Substring(From.IndexOf('@') + 1); SmtpMail.SmtpServer = "smtp." + From.Substring(From.IndexOf('@') + 1); //開始發送郵件 try { SmtpMail.Send(objMailMessage); return "郵件發送成功！"; } catch (System.Net.Mail.SmtpException ex) { return ex.Message; } //核心代碼結束 } } ~~~ 2、Web頁面中使用及調用示例，代碼如下： ~~~ <%@ Page Language="C#" AutoEventWireup="true" CodeFile="MailSendDemo.aspx.cs" Inherits="demo_MailSendDemo" ValidateRequest="false" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script language="javascript" type="text/javascript"> //獲取附件 function getAttachFile() { var file_value = document.getElementById("File1").value; document.getElementById("HiddenField1").value = file_value; } </script> </head> <body> <form id="form1" runat="server"> <div> 發給：<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br /> 抄送：<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox><br /> 密送：<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox><br /> 主題：<asp:TextBox ID="TextBox5" runat="server"></asp:TextBox><br /> 內容：<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox><br /> 附件：<input id="File1" type="file" /> <br /> <asp:Button ID="btnSend" runat="server" Text="發送" OnClientClick="getAttachFile()" OnClick="btnSend_Click" /><br /> <asp:Label ID="Label1" runat="server" Text=""></asp:Label> </div> <asp:HiddenField ID="HiddenField1" runat="server" /> </form> </body> </html> ~~~ string a = mails.SendeEmail(TextBox1.Text, "你的郵箱號", "郵箱密碼", TextBox2.Text, TextBox4.Text, TextBox5.Text, filePath, TextBox3.Text); 這里的在你實際使用的時候，替換成你的發送方郵箱賬號和密碼即可。 ~~~ using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class demo_MailSendDemo : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void btnSend_Click(object sender, EventArgs e) { //實例郵件幫助類，并進行郵件發送 MailHelper mails = new MailHelper(); string filePath = HiddenField1.Value; string a = mails.SendeEmail(TextBox1.Text, "你的郵箱賬號", "郵箱密碼", TextBox2.Text, TextBox4.Text, TextBox5.Text, filePath, TextBox3.Text); Label1.Text = a; } } ~~~
