Answer 1

Try Linq :

var target = File
  .ReadLines(@"C:\Source.txt")
  .Select(line => line.Replace(" ", "| ") + "|");

File.WriteAllLines(@"C:\Target.txt", target);

Answer 2

string input = "4 4 4100100001063D 1CBSME 150312 40001063ANTE LECO METERING C 3460025.57LKR";
string pattern = "\\s+";
string replacement = "|";
Regex rgx = new Regex(pattern);
string result = rgx.Replace(input, replacement) + replacement;

This should replace all the spaces with "|" and then we are appending "|" to get expected output.
