You can just simply use the Split method right? or I'm I missing something?
string s = "His duty to write a computer program, he did not do it very well, I gave him a score of 5, I hope he do better next time.";
string[] sentences = s.Split(',');
foreach (string sentence in sentences) {
Console.WriteLine(sentence);
}
Output:
His duty to write a computer program
he did not do it very well
I gave him a score of 5
I hope he do better next time.
