Sort a list by Code, Then by Name

问题

I have a list of objects. I sort this list by Code by writing this line:

Result.Sort(delegate(Position p1, Position p2) { return p1.Code.CompareTo(p2.Code); });

But I want to sort this line first by Code and then by Name. How to I do this?

回答1:

Without LINQ:

Result.Sort(delegate(Position p1, Position p2) 
            { 
                var byCode = p1.Code.CompareTo(p2.Code); 
                return byCode == 0 ? p1.Name.CompareTo(p2.Name) : byCode; 
            });

Or the same logic using comparers:

Result.Sort(new PositionComparer());
class PositionComparer : IComparer<Position>
{
    public int Compare(Position p1, Position p2) 
    { 
        var byCode = p1.Code.CompareTo(p2.Code); 
        return byCode == 0 ? p1.Name.CompareTo(p2.Name) : byCode; 
    }
}

Why won't you use LINQ?

var ordered = list.OrderBy(x => x.Code).ThenBy(x => x.Name).ToList();
