c#邮箱发送和接收

简洁版发送：

//web.config ---文件

<?xml version="1.0" encoding="utf-8"?>

</configuration>

//Defult.aspx ---文件

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html>



//Defult.aspx.cs ---文件
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Mail;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        //发送邮件
        SmtpClient smtp = new SmtpClient("smtp.163.com");
        //设置邮件类型（1.发送者 2.接受者 3.邮件体 4.登录信息）
        //1.
        string address = System.Configuration.ConfigurationManager.AppSettings["email"].ToString();
        MailAddress from = new MailAddress(address);

        //2.
        MailAddress to = new MailAddress(tetTo.Text);

        //3.
        MailMessage mail = new MailMessage(from,to);
        mail.Subject = tetSubject.Text;
        mail.Body = tetBody.Text;
        //4.
        string pwd = System.Configuration.ConfigurationManager.AppSettings["password"].ToString();
        NetworkCredential cred = new NetworkCredential(address,pwd);
        smtp.Credentials = cred;

        smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
        //发送
        smtp.Send(mail);
    }
}

二、完全版发送接收：（在这个方法中需要用到OpenPop.dll文件链接：http://pan.baidu.com/s/1bnwjWJH）

//default.aspx ---文件

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html>

//default.aspx.cs ---文件

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using OpenPop.Pop3;
using OpenPop.Mime;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
List<MailItem> list = new List<MailItem>();

//实例化pop3访问对象
Pop3Client pop3 = new Pop3Client();
//链接到邮件服务器
pop3.Connect("pop3.sina.com",110,false);
//身份验证
pop3.Authenticate("z1n10527@sina.com","abcde12345");

//读邮件列表
//1.获取邮件的个数
int count = pop3.GetMessageCount();
//2.遍历显示出来
for (int i = 1; i <= count; i++)
{
Message msg = pop3.GetMessage(i);
MailItem data = new MailItem();
data.NO = i;
data.FromAddress = msg.Headers.From.Address;//发送者的邮箱地址
data.FromSender = msg.Headers.From.DisplayName;//发送者的名子
data.Date = msg.Headers.DateSent;//邮件的发送时间
data.Subject = msg.Headers.Subject;//邮件的主题
data.Body = msg.MessagePart.GetBodyAsText();
list.Add(data);
}
//断开链接
pop3.Disconnect();

//绑定显示
Repeater1.DataSource = list;
Repeater1.DataBind();
}
}

public class MailItem
{
public int NO { get; set; }
public string FromSender { get; set; }
public string FromAddress { get; set; }
public DateTime Date { get; set; }
public string Subject { get; set; }
public string Body { get; set; }
}

//details.aspx ---文件

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Details.aspx.cs" Inherits="Details" %>

<!DOCTYPE html>



//details.aspx.cs  ---文件

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using OpenPop.Pop3;
using OpenPop.Mime;
public partial class Details : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Request["id"] != null)
        {
            //获取邮件代号
            int no = Convert.ToInt32(Request["id"]);
            //根据邮件代号查找邮件
            Pop3Client pop3 = new Pop3Client();
            pop3.Connect("pop3.sina.com",110,false);
            pop3.Authenticate("z1n10527@sina.com","abcde12345");
            Message msg =pop3.GetMessage(no);
            //显示
            lblSubject.Text = msg.Headers.Subject;
            lblSender.Text = msg.Headers.From.DisplayName + msg.Headers.From.Address;
            lblDate.Text = msg.Headers.DateSent.ToString();
            lblBody.Text = msg.MessagePart.GetBodyAsText();
            //断开链接
            pop3.Disconnect();
        }
    }
}

一、邮件发送：.NET中自带SMTP邮件发送的类——SmtpClient

第一步：导入命名空间：

using System.Net.Mail;
using System.Net;

第二步：编写邮件发送代码：

//1.实例化发邮件的类
SmtpClient smtp = new SmtpClient("smtp.sina.com");

//2.构建邮件对象。邮件对象常见的一般包括：发送邮箱，接收邮箱，标题，内容四大部分

MailAddress from = new MailAddress("z1n10527@sina.com"); //发送者的邮箱地址
MailAddress to = new MailAddress("z1n10426@sina.com"); //接收者的邮箱地址
MailMessage mail = new MailMessage(from, to); //实例化邮件对象
mail.Subject = txtSubject.Text; //邮件的标题
mail.Body = txtBody.Text; //邮件的内容

//3.设置邮箱登录验证凭据

NetworkCredential cred = new NetworkCredential("发送者的邮箱用户名","发送者的邮箱密码"); //创建凭据对象
smtp.Credentials = cred; //把凭据对象赋给邮件发送类

//4.发送

smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Send(mail);

二、邮件接收：.NET中没有POP3邮件接收的类，邮件的内容和格式比复杂，手动写代码进行解析很麻烦，也容易出错，开发中我们可以借助第三方插件来实现。

OpenPOP.NET插件的地址：http://sourceforge.net/projects/hpop/

第一步：添加引用：OpenPop.dll

第二步：导入命名空间：

using OpenPop.Pop3;
using OpenPop.Mime;

第三步：编写邮件实体类：

public class MailItem
{
public int NO { get; set; }
public string FromSender { get; set; }
public string FromAddress { get; set; }
public DateTime Date { get; set; }
public string Subject { get; set; }
public string Body { get; set; }
}

第四步：编写邮件读取代码

protected void Page_Load(object sender, EventArgs e)
    {
        List<MailItem> list = new List<MailItem>();

        //实例化pop3访问对象
        Pop3Client pop3 = new Pop3Client();
        //链接到邮件服务器
        pop3.Connect("pop3.sina.com",110,false);
        //身份验证
        pop3.Authenticate("z1n10527@sina.com","abcde12345");

        //读邮件列表
        //1.获取邮件的个数
        int count = pop3.GetMessageCount();
        //2.遍历显示出来
        for (int i = 1; i <= count; i++)
        {
            Message msg = pop3.GetMessage(i);
            MailItem data = new MailItem();
            data.NO = i;
            data.FromAddress = msg.Headers.From.Address;//发送者的邮箱地址
            data.FromSender = msg.Headers.From.DisplayName;//发送者的名子
            data.Date = msg.Headers.DateSent;//邮件的发送时间
            data.Subject = msg.Headers.Subject;//邮件的主题
            data.Body = msg.MessagePart.GetBodyAsText();
            list.Add(data);
        }
        //断开链接
        pop3.Disconnect();

        //绑定显示
        Repeater1.DataSource = list;
        Repeater1.DataBind();
    }
}
