Question

I am trying to parse data I am getting from an arduino robot I created. I currently have my serial program up and running and I am able to monitor the data being sent and received by my computer.

The data I am trying to get from the robot includes: speed, range, and heading. The data being sent from the arduino are floats.

I use a single character to denote what the data being received is by either a S,R, or H. For example:
R150.6

This would denote that this is range data and 150.6 would be the new range to update the program with.

I’m a little stuck trying to figure out the best way to parse this using c# as this is my first c# program.

I have tried with a similar code to:

if (RxString[0] == 'R')
            Range = double.Parse(RxString);

I read on the site to use regular expressions, however I am having a hard time figuring out how to incorporate it into my code.

This is the link I was using for guidance:

String parsing, extracting numbers and letters

Answer 1

You’re almost there. If you’re always starting with a single letter, try Range = double.Parse(RxString.Substring(1)). It will read from the second character on.
