This will work on inputs like ab, ac, Convert(ab,ac),test,bc,mc, too

Just split your input acccording to ,\\s+ or , + regexes. \\s+ matches one or more space characters.

string value = "ab, ac, Convert(ab,ac), test";
string[] lines = Regex.Split(value, @", +");
foreach (string line in lines) {
Console.WriteLine(line);
}

Output:

ab
ac
Convert(ab,ac)
test
