How to convert Taleo JSON Text data back to original binary data for PDF in C#?

Summary

Taleo converted binary PDF file to a JSON Text string, how I get the original binary data back using C#?

Content

I am attempting to convert the text string that holds the binary information for the Taleo resume files back into binary format to save as a PDF.

I am able to get, successfully call and parse the data from the Taleo API URL:  Candidate.RelationshipUrls.Resume

From my understanding, the "Content" field of the returned JSON data holds the guts of the data for that file, but since the Taleo API returns JSON data which is text, any binary file data - like PDFs - have to be converted/encoded to a text format so it can be put into JSON to get to my process.
