Question

I’m trying to figure out a way to parse out a base64 string from with a larger string.

I have the string "Hello <base64 content> World" and I want to be able to parse out the base64 content and convert it back to a string. "Hello Awesome World"

Answers in C# preferred.

Edit: Updated with a more real example.

--abcdef
\n
Content-Type: Text/Plain;
Content-Transfer-Encoding: base64
\n
<base64 content>
\n
--abcdef--

This is taken from 1 sample. The problem is that the Content…. vary quite a bit from one record to the next.
