I have a reporting interface where the end user gets to select multiple fields for the sort order of the returned report. The problem I am having is that I can't really chain the OrderBy / ThenBy methods, since I'm iterating through a list of sort fields. I'm thinking something like this:

foreach (string sort in data.SortParams)
{
    switch (sort)
    {
        case "state":
            query = query.ThenBy(l => l.RegionCode);
            break;
        case "type":
            query = query.ThenBy(l => l.Type);
            break;
        case "color":
            query = query.ThenBy(l => l.Color);
            break;
        case "category":
            query = query.OrderBy(l => l.Category);
            break;
    }
}

(Note: I've removed the switch determining if this is the first sort item for simplicity's sake.)

Any thoughts on how to iterate through a collection to determine the sort order?
