1、編寫一個通用的郵件傳送操作類：MailHelper.cs,程式碼如下：

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: 在此處新增建構函式邏輯
  //
 }

    /// <summary>
    /// 郵件傳送操作
    /// </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">傳送主題</param>
    /// <param name="Attachment">附件資訊</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;


        // 建立郵件訊息
        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; //傳送郵件的標題

        //郵件內容
        objMailMessage.Body = Body;//傳送郵件的內容

        // 建立一個附件物件
        if (Attachment != "")
        {
            objMailAttachment = new MailAttachment(Attachment);//傳送郵件的附件 c:\\test.txt
            objMailMessage.Attachments.Add(objMailAttachment);//將附件附加到郵件訊息物件中
        }

        //接著利用SMTP來傳送郵件，需要使用Microsoft .NET Framework SDK v1.1和它以上的版本
        //基本許可權
        objMailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");
        //使用者名稱
        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);
        //如果沒有上述三行程式碼，則出現如下錯誤提示：伺服器拒絕了一個或多個收件人地址。伺服器響應為: 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);
        //開始傳送郵件

        try
        {
            SmtpMail.Send(objMailMessage);
            return "郵件傳送成功！";
        }
        catch (System.Net.Mail.SmtpException ex)
        {
            return ex.Message;
        }
        //核心程式碼結束
    }


}


2、Web頁面中使用及呼叫示例，程式碼如下：


<%@ 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="傳送" 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);

這裡的在你實際使用的時候，替換成你的傳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)
    {       

        //例項郵件幫助類，並進行郵件傳送
        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;
    }
}
