高手请帮下POP3解码。。。。。。 问题是接收过来如何实现MIME解码,否则全是乱码 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 看System.Web.Services.Protocols 命名空间,里面有 Mime相关的类 mime's encoding method is base64, you can get the begining,and get the code and decode it email的编码有两种,base64和qb编码,还要识别他的信件头,有点麻烦的,在网上找一下资料吧, 我也有同样地问题得不到解决,还有charset的问题,html邮件显示的问题。希望能有英雄豪杰拔刀相助!!!!!!!!!!!!!!!!!!!!!!!!!!!! 送我一份吧?[email protected] 如果是中文出现乱码的问题,可能RdStrm是这样定义的:RdStrm=new StreamReader(NetStrm),这样使用的编码是默认的UTF-8,这样定义RdStrm=new StreamReader(NetStrm,System.Text.Encoding.GetEncoding("gb2312"))可以解决中文的乱码问题。 如果是要处理MIME数据,这可能需要专业人员来处理。 换成这句RdStrm=new StreamReader(NetStrm,System.Text.Encoding.GetEncoding("gb2312"))也是乱码吗? 我也要一份[email protected] 我根据你的代码写了一段代码,测试没有问题,改成下面这样看看,//根据邮件编号从服务器获得相应邮件string Data = "RETR "+ MailNum.Text+CRLF;byte[] szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());NetStrm.Write(szData,0,szData.Length);StreamReader RdStrm=new StreamReader(NetStrm,System.Text.Encoding.GetEncoding("gb2312"));string szTemp = RdStrm.ReadLine();string ss="";if (szTemp.IndexOf("+OK")>=0){ while ((szTemp=RdStrm.ReadLine())!="."){ss+=szTemp;}MessageBox.Show(ss); 我想知道的是如何取得邮件的附件数,和分别取得附件的base64编码。最好能用正则表达式。 奇怪了。我的怎么还是老样子,我给你整段的代码,你帮我看看好吗?非常感谢:using System;using System.Drawing;using System.Collections;using System.ComponentModel;using System.Windows.Forms;using System.Data;using System.Net;using System.Net.Sockets;using System.IO;namespace MailReceiver{ /// <summary> /// Form1 的摘要说明。 /// </summary> public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.Label label1;
