You could try the below regex which uses positive lookahead,

string value = @"apple, orange, ""baboons, cows"", rainbow, ""unicorns, gummy bears""";
string[] lines = Regex.Split(value, @", (?=(?:""[^""]*?(?: [^""]*)*))|, (?=[^"",]+(?:,|$))");

foreach (string line in lines) {
Console.WriteLine(line);
}

Output:

apple
orange
"baboons, cows"
rainbow
"unicorns, gummy bears"
