Regular Expression to Replace Specific character between 2 immediate letters or numbers?

I agree with that opinion, that regular expressions should be the last resort. If you think , you can't do without them anyway, then try the following:

string pattern = @"(?<="".+),\s(?=.+"")";
string replacment = @" - ";
string modLine = "";
foreach (var item in tmp.Split(new string[] {Environment.NewLine}, StringSplitOptions.None)) {
    MatchCollection matches = Regex.Matches(item, pattern);
    if (matches.Count > 0) {
        foreach (var match in matches) {
            modLine = Regex.Replace(item, match.ToString(), replacment);
        }
    }

    Console.WriteLine(modLine );
}

This simply wipes out the entire output file. The result is a blank file.



Thanks for the input.
