List<Myobject> MyList = new List<Myobject>();

Answer 1

You can use List.Sort

l.Sort((p, q) => p.Category.CompareTo(q.Category));

The advantage over the LINQ OrderBy is that you’ll order the list in-place instead of generating an IOrderedEnumerable<T> that then you have to re-transform in a List<T>.
