It's not clear why you're using a double slash here...

string[] details = key.Split('/');

should work fine. (Note that forward-slashes don't have to be escaped in C#.) For example:

using System;

class Test
{
    static void Main()
    {
        string text = "/mercedes-benz/190-class/1993/";
        string[] bits = text.Split('/');
        foreach (string bit in bits)
        {
            Console.WriteLine("'{0}'", bit);
        }
    }
}

Output:

''
'mercedes-benz'
'190-class'
'1993'
''

The empty strings are due to the leading and trailing slashes. If you want to avoid those, you can use

string[] details = key.Split(new[] {'/'}, StringSplitOptions.RemoveEmptyEntries);

Notes:

• car_facts is a highly unconventional name in C#. Normally you'd have something like CarFacts (or potentially just Car, CarInfo etc). Likewise car_fact_list would normally be carFactList or something similar.

• This code doesn't do what you expect it to:

  key.Trim();
  

  Strings are immutable in .NET - so Trim() returns a reference to a new string rather than changing the contents of the existing one. You may want:

  key = key.Trim();
  

• You're currently assigning a value to car_detail but never using it. Why?

• Parsing HTML using regular expressions is a really bad idea in general. Consider using HTML Agility Pack or something similar.
