500分赠送怎么才能把收到的邮件编码还原

先找两个回车换行。找到后，再找后面的两个回车换行。
中间的内容即是base64编码后的内容。
使用
byte[] bytes=Convert.FromBase64String(中间的内容);
System.Text.Encoding.Default.GetString(bytes);
这种方法即可转换成可视的内容。
祝你好运

我能用VB.net解决，需要的话可以找我。

我的方法简单，把邮件存为winzip.uu，然后用winzip解压后打开里面的文件就好了：）

还有一点疑问就是附件的格式有zip jpg doc rar 我想让他们相应的还原，可以吗？还有就是主题那些编码怎么还原成中文就这点问题了然后我告诉你们来领分就是了

比如收到了中文主题的信件但是用记事本打开里面的主题编码是 =?utf-8?B?UkU6IOmdnuW4uOmCruS7tiDmtYvor5U=?=怎么把它还原成中文

关于邮件解码的重点在于了解MIME这种文件格式。其中对于内容对象和附件的分离和解码是解决这个问题的重点。内容对象和附件的分离非常容易，只要找到隔离标志，就可以进行分离。对于解码，在Microsoft .NET下，提供了众多的关于文本对象的编码和解码函数(System.Text)，不用自己手工编写了，工作量减轻不少，唯一要做解码工作的就是QP编码(Quoted-Printable)的解码工作。针对你举的例子------=_NextPart_000_0009_01C37B0E.911050B0 (节的隔离标志）

有没考虑用其他组件？PowerTCP Mail For .Net

我也在写email的pop3解码组件，
遇到以下问题：
为什么发件人有时是abc<[email protected]>；有时又是[email protected]<abc>
如果判断<>里是否有发件人？

建一个文本文件，把你的一堆堆乱码copy入。改名为mht文件类型。双击即可看到解码后的信息

我认为不是mht文件，而是eml文件。

其实没有这么麻烦，只要在转发到Outlook Express中，编码方式改一下（如改为简体中文等等），几种编码方式都试试。一般就可以解决了。我就遇到过这种情况，用网上搜来的方法包括winzip的方法都不好使。后来用这种方法解决了。

Take it easy ,try the former method and good luck!

如果主题为：
“=?utf-8?B?UkU6IOmdnuW4uOmCruS7tiDmtYvor5U=?=”解码：
subject=System.Text.Encoding.GetEncoding("utf-8").GetChars(Convert.FromBase64String("UkU6IOmdnuW4uOmCruS7tiDmtYvor5U="))Convert VB.NET的转换函数，在C#应该有等价的。
