让我们来看看的意思MIME编码：？？？？

Let's have a look at the meaning of the MIME encoding:

=?utf-8?B?...something...?=
    ^   ^
    |   +--- The bytes are Base64 encoded
    |
    +---- The string is UTF-8 encoded

所以，解码此，取 ...什么... 你的字符串（ 2LPZhNin2YU = 你的情况），然后

So, to decode this, take the ...something... out of your string (2LPZhNin2YU= in your case) and then

1. 扭转Base64编码

1. reverse the Base64 encoding

var bytes = Convert.FromBase64String("2LPZhNin2YU=");

var text = Encoding.UTF8.GetString(bytes);

文本。code>现在应包含所期望的结果。

text should now contain the desired result.
