string strName = "jMeyers";
string strNamej = "john jacob jingleheimer Schmidt";

strName = strName .Replace("j" , "J");
strNamej =  strNamej.Replace("j" , "J");

strName will be "JMeyers" strName will be "John Jacob Jingleheimer Schmidt"


etc

Make Our Own String function

protected static void WriteColorFull(string s)
        {
            //Save current console color so we can restore it when we are done
            //We don't want to leave the console with a random color
            ConsoleColor originalConsoleColor = Console.ForegroundColor;

            for (int index = 0; index < s.Length; index++)
            {

                Console.ForegroundColor = mycolors[(mycolors.Length + index) % mycolors.Length];   //Rotate through colors
                Console.Write(s[index]);    //Write the current letter from the string

            }
            Console.Write("\n");

            //Restore Console
            Console.ForegroundColor = originalConsoleColor;

        }

        //An array of console colors
        private static ConsoleColor[] mycolors =
        {
            ConsoleColor.Red,
            ConsoleColor.Magenta,
            ConsoleColor.DarkMagenta,
            ConsoleColor.DarkGreen,
            ConsoleColor.DarkRed,
            ConsoleColor.DarkGray,
            ConsoleColor.DarkBlue,
            ConsoleColor.Blue,
            ConsoleColor.Gray,
            ConsoleColor.Green,
