C# Binary string to Bytearray without conversion

Question

I call an API to get a PDF file. The API returns it as a string with binary data. Now I need to save it to a file without any conversion of the data. How can I do this in C#?

I have been trying

    string file = await service.GetDocumentsAsync(document.FileId);  //  Gets the filedata
    byte[] byteArray = file.Select (c => (byte)c).ToArray ();
    using (var stream = new FileStream($"c:\\temp\\{document.Id}.pdf", FileMode.Create))
    {
        stream.Write (byteArray,0,file.Length);
        stream.Close ();
    }

I do get the PDF, but it only has blank pages.

The beginning of the string when i look at it in the Debugger:

"a string with binary data" what does that mean? Base64-encoded? — Fildor

@Longoon12000 Because a PDF file will generally contain data which would be corrupted by treating it as a string (text) instead an treating it as bytes. — Andrew Morton

service.GetDocumentsAsync needs to give a byte[], not a string. — Andrew Morton

As suggested we had to change what the API returned. We use RestSharp and had to use Response.RawByte iso. Response.
