Parse multiple doubles from string in C#

Say I have a line of text that looks as follows:

“45.690 24.1023 .09223 4.1334”

What would be the most efficient way, in C#, to extract just the numbers from this line? The number of spaces between each number varies and is unpredictable from line to line. I have to do this thousands of times, so efficiency is key.

Thanks.

Answer 1

IEnumerable<double> doubles = s.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries)
                               .Select<string, double>(double.Parse)

Updated to use StringSplitOptions.RemoveEmptyEntries since the number of spaces varies
