Use string.Split

String.Split Method (String[], StringSplitOptions) (System)[^]

string[] x = text.Split(new char[]{' '}, StringSplitOptions.RemoveEmptyEntries);

If you have multiple lines you might need to split on the new line then go through each line and split on the space. Or just read the data line by line and split on space rather than reading it in one chunk.

Solution 2

It is assumed that your text uses \n as line break.

var text = "W S 6\nW H 11\nW D 6\nW C 8\nW N 9\n\nN S 7\nN H 2\nN D 6\nN C 5\n\nN N 4\nE S 6\nE H 11\nE D 6\nE C 8\nE N 9\n";

Then you could split this text like this:

var array = Regex.Split(text, "\n\n");

Splitting with a Regex.Split is kinda overkill when you want to split by 1 char. Try var array = read.Split('\n');.

Beware of '\r' as it can sometime accompany \n depending on the source of the string. It might be an idea to trim the strings once split. Linq would be easiers:

C#

using(StreamReader reader = new StreamReader(uploadedFile.InputStream))
    {
        string read = reader.ReadToEnd();
        string[] Array = read.Split(read,"\n").Select(s=>s.Trim({' ','\r'}).ToArray();
    }
