Stumbled across this question on StackOverflow the other day, definitely one for the interview! The question goes:
How do you convert a string such as “01110100011001010111001101110100” to a byte array then used File.WriteAllBytes such that the exact binary string is the binary of the file. In this case it would be the the text “test”.
Here’s my take on the answer :-)
var binaryStr = "01110100011001010111001101110100"; var byteArray = Enumerable.Range(0, int.MaxValue/8) .Select(i => i*8) // get the starting index of which char segment .TakeWhile(i => i < binaryStr.Length) .Select(i => binaryStr.Substring(i, 8)) // get the binary string segments .Select(s => Convert.ToByte(s, 2)) // convert to byte .ToArray(); File.WriteAllBytes("C:\temp\test.txt", byteArray);
I specialise in rapidly transitioning teams to serverless and building production-ready services on AWS.
Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.
Check out my new course, Complete Guide to AWS Step Functions. In this course, we’ll cover everything you need to know to use AWS Step Functions service effectively. Including basic concepts, HTTP and event triggers, activities, callbacks, nested workflows, design patterns and best practices.
