Question

I’m trying to convert a string that contains multiple numbers, where each number is separated by white space, into a double array.

For example, the original string looks like:

originalString = "50 12.2 30 48.1"

I’ve been using Regex.Split(originalString, @”\s*”), but it’s returning an array that looks like:

[50
""
12
"."
2
""
...]

Any help is much appreciated.

Answer 1

Regex.Split(originalString, @"\s+").Where(s => !string.IsNullOrWhiteSpace(s))

The Where returns an IEnumerable with the null/whitespace filtered out. if you want it as an array still, then just add .ToArray() to that chain of calls.

The + character is necessary because you need a MINIMUM of one to make this a correct match.
