Question

To sort a List on multiple criteria, I’m currently doing something like:

collection.Sort((f1, f2) =>
{
    var comp = f1.FirstCriteria.CompareTo(f2.FirstCriteria);
    return comp != 0 ? comp : f1.SecondCriteria.CompareTo(f2. SecondCriteria);
});

But wouldn’t it be nice to be able to do something like:

collection.MultipleSort(f1.FirstCriteria, f2.FirstCriteria)
          .Then(f1.SecondCriteria, f2.SecondCriteria)

Any ideas for a good implementation of a fluent interface for sorting?

Answer 1

You mean something like the following?

using System.Linq;

collection.OrderBy(t => t.FirstCriteria).ThenBy(t => t.SecondCriteria);
