String Manipulation using Split Method

Question

I having a problem on using Split Method().

I have a string like this:

string diagnosis = "001.00 00 002.01 00 003.00 01";

And output should be:

001.00
002.01
003.00

I tried in this two ways to remove the two digits:

1

    string[] DiagnosisCodesParts = diagnosis.Split();
    if (DiagnosisCodesParts[x].Length > 3)
       {
         //here
       }

And..

2

string DiagnosisCodestemp = diagnosis.Replace(" 00 ", " ").Replace(" 01 ", " ").Replace(" 02 ", " ") 

Is there other way to remove the two digits?

Answer 1

Clearest to me would be

Regex.Matches(diagnosis, @"\d+\.\d+").Cast<Match>().Select(m => m.Value);
