Found myself doing something similar, and I appreciate having a point-of-departure with this discussion. This is my solution, placed as an extension method to the string class in the context of a console application.

using System;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string piratese = "avastTharMatey";
            string ivyese = "CheerioPipPip";

            Console.WriteLine("{0}\n{1}\n", piratese.CamelCaseToString(), ivyese.CamelCaseToString());
            Console.WriteLine("For Pete\'s sake, man, hit ENTER!");
            string strExit = Console.ReadLine();
        }

    }

    public static class StringExtension
    {
        public static string CamelCaseToString(this string str)
        {
            StringBuilder retVal = new StringBuilder(32);

            if (!string.IsNullOrEmpty(str))
            {
                string strTrimmed = str.Trim();

                if (!string.IsNullOrEmpty(strTrimmed))
                {
                    retVal.Append(char.ToUpper(strTrimmed[0]));

                    if (strTrimmed.Length > 1)
                    {
                        for (int i = 1; i < strTrimmed.Length; i++)
                        {
                            if (char.IsUpper(strTrimmed[i])) retVal.Append(" ");

                            retVal.Append(char.ToLower(strTrimmed[i]));
                        }
                    }
                }
            }
            return retVal.ToString();
        }
    }
}
