Without regex you can do something like (or perhaps something more concise using LINQ):

(Note: no error checking is there, you should add it)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace SO
{
    class Program
    {
        static void Main(string[] args)
        {
            String test = "AStringInCamelCase";
            StringBuilder sb = new StringBuilder();

            foreach (char c in test)
            {
                if (Char.IsUpper(c))
                {
                    sb.Append(" ");
                }
                sb.Append(c);
            }

            if (test != null && test.Length > 0 && Char.IsUpper(test[0]))
            {
                sb.Remove(0, 1);
            }

            String result = sb.ToString();
            Console.WriteLine(result);
        }
    }
}

this gives the output

A String In Camel Case
