Question Updated

I have a generic list which can contains the following values:

Sector 1
Sector 2
Sector 4

or the following value:

All Sectors

I want to format this values in a string like this:

Sector 1 & 2 & 4 - 

or

All Sectors -

Currently, I have the following code to format the same. It works, but is very complicated.

string retrieveSectors += sectors.Count == 0
                               ? string.Empty
                               : sectors.OrderBy(
                               y =>
                               y.Sector.Substring(
                               y.Sector.Length - 1, 1)).
                               GroupBy(g => g.Sector).Select(
                               g => g.First()).ToList().Aggregate(
                               retrieveSectors,
                               (current, y) =>
                               (current == retrieveSectors
                               ? current +
                               y.Sector
                               : current + " & " +
                               y.Sector.
                               Substring(
                               y.Sector.
                               Length - 1, 1))) + " - "

In the above code, the variable sector is the generic list. Can someone help me to attain the results in a simplified way.? Or may be modify the above code so that it is more understandable.

Any help appreciated. Thanks

Maybe a little more simple:

    string retrieveSectors =
        string.Format(
        "sectors {0} -",
        sectors.Select(s => s.Replace("sector ", "").Replace("|", ""))
            .OrderBy(s => s)
            .Aggregate((a, b) => string.Format("{0} & {1}", a, b))
        );
