How can I capitalize the first letter of each sentence in C# using char? I'm very new to C#, so simplified responses would be appreciated : Sentence capitalization:
       private string SentenceCapitalizer(string input)
        {
            char delim = '.';
            string letter1;
            string[] tokens = input.Split(delim);
            foreach (string phrase in tokens)
            {
                letter1 = phrase.Remove(0);
                letter1.ToUpper();
            }

            return input;
        }
