Method public static bool IsWhiteSpace(char c) public static bool IsWhiteSpace(string s, int index) public static char Parse(string s) public static char ToLower(char c) public static char ToLower(char c, CultureInfo culture)
Meaning Returns true if c is a whitespace character, such as a space or tab Otherwise, returns false Returns true if s[index] is a whitespace character, such as a space or tab Otherwise, returns false Returns the char equivalent of the character in s If s contains more than one character, a FormatException is thrown Returns the lowercase equivalent of c if c is an uppercase letter Otherwise, c is returned unchanged Returns the lowercase equivalent of c if c is an uppercase letter Otherwise, c is returned unchanged The conversion is handled in accordance with the specified cultural information CultureInfo is a class defined in SystemGlobalization Returns the lowercase version of c independently of the cultural settings Returns the string representation of the value of the invoking Char Returns the string representation of c Returns the string representation of the invoking Char using the specified culture information Returns the uppercase equivalent of c if c is a lowercase letter Otherwise, c is returned unchanged Returns the uppercase equivalent of c if c is a lowercase letter Otherwise, c is returned unchanged The conversion is handled in accordance with the specified cultural information CultureInfo is a class defined in SystemGlobalization Returns the uppercase version of c independently of the cultural settings Attempts to convert the character in s into its char equivalent If successful, the value is stored in result and true is returned If s contains more than one character, false is returned This differs from Parse( ), which throws an exception on failure
