Try this:

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

public class Program
{
    public static void Main()
    {
        Console
            .WriteLine(
                SeparateByCamelCase("TestString") == "Test String" // True
            );
    }

    public static string SeparateByCamelCase(string str)
    {
        return String.Join(" ", SplitByCamelCase(str));
    }

    public static IEnumerable SplitByCamelCase(string str) 
    {
        if (str.Length == 0) 
            return new List();

        return 
            new List 
            { 
                Head(str) 
            }
            .Concat(
                SplitByCamelCase(
                    Tail(str)
                )
            );
    }

    public static string Head(string str)
    {
        return new String(
                    str
                        .Take(1)
                        .Concat(
                            str
                                .Skip(1)
                                .TakeWhile(IsLower)
                        )
                        .ToArray()
                );
    }

    public static string Tail(string str)
    {
        return new String(
                    str
                        .Skip(
                            Head(str).Length
                        )
                        .ToArray()
                );
    }

    public static bool IsLower(char ch) 
    {
        return ch >= 'a' && ch <= 'z';
    }
}
