I\'m looking for a function to convert a string of text that is in UpperCase to SentenceCase. All the examples I can find turn the text into TitleCase.

Answer 1

public string GetSentenceCase(string ReqdString) {
    string StrInSentCase = "";
    for (int j = 0; j < ReqdString.Length; j++) {
        if (j == 0) {
           StrInSentCase = ReqdString.ToString().Substring(j, 1).ToUpper();
        }
        else {
            StrInSentCase = StrInSentCase + ReqdString.ToString().Substring(j, 1).ToLower();
        }
    }
    return StrInSentCase.ToString();
}
