Question

When using linq and you have

c.Sort()

Is there any good inline way of defining a Comparison and/or IComparer class w

Answer 1

Jon's answer is great but can be a little bit out of date, with release of .NET 4.5 we now (finally!) have this awesome method Comparer.Create

items.Sort((x, y) => x.Value.CompareTo(y.Value)); //sorting List                
items.OrderBy(x => x, Comparer.Create((x, y) => x.Value.CompareTo(y.Value))); //sorting IEnumerable

Assuming Item is defined something like:

class Item
{
    public readonly int Key;
    public readonly string Value;

    public Item(int key, string value)
    {
        Key = key;
        Value = value;
    }
}
