I need to snip each line like below;

0011 8 0E 00 00 00 C3 3C D4 FF

and past all the snippets into a textbox.

Answer 1

You could use regex provided the format of each line is the same as the above:

using System.Text.RegularExpressions;

var input = @"
    21)      3000.5  Rx         0011  8  0E 00 00 00 C3 3C D4 FF 
    21)      3000.5  Rx         0011  8  0E 00 00 00 C3 3C D4 FE 
    21)      3000.5  Rx         0011  8  0E 00 00 00 C3 3C D4 FD 
";

var results = new Regex(@"^\s*\d+\)\s+[\d.]+\s+Rx\s+(.+)$", RegexOptions.Multiline).Matches(input)
	.Select(m => m.Groups[1].Value.Trim().Replace("  ", " "))
	.ToArray();

foreach (var result in results) {
	Console.WriteLine(result);
}

Which produces:

0011 8 0E 00 00 00 C3 3C D4 FF
0011 8 0E 00 00 00 C3 3C D4 FE
0011 8 0E 00 00 00 C3 3C D4 FD
