Remove spaces in the string array

Question

I have a text file that contains numbers in this format :

84  152  100       
86  149   101     
83   149   99    
86  142   101

How can I remove the spaces and bring it in this shape :

This is what I have tried so far :

string path = Directory.GetCurrentDirectory();
string[] lines = System.IO.File.ReadAllLines(@"data_1_2.txt");
string[] line = lines[0].Trim().Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);

But the result of this input is :

84
152
100

Did you tried anything so far?

Use a bit of LINQ magic:

lines = lines.Select(l => String.Join(" ", l.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries))).ToArray();

It will split each line using space as a separator, remove empty entries and join them back using space as a separator again.

Just a question for you @MarcinJuraszek, when I use such a thing. Console.WriteLine(line.Length); Console.WriteLine(lines.Length); Its giving me same dimension, I tried to add a new coloum, but there is no affect.

I don't really understood what you're asking about right now.

Now after I have omitted all the spaces, I would like to know its dimension, how would I do that?

You've omitted the spaces, but it's still an array of strings, not a multidimensional array of numbers.

You can use a simple regular expression:

lines = lines.Select(line => Regex.Replace(line, @"\s+", " ")).ToArray();
