Question

Is there a way in .NET that I can sort my collection when I do not know what types of objects at run time I will pass to this collection and also by avoiding Reflection.

any thoughts?

Answer 1

You do need some way of comparing elements. The usual way is to demand IComparable:

class MyCollection<T> where T : IComparable<T>
{
}

or use an IComparer, either for the Sorting method or the constructor:

class MyCollection<T> // where T : IComparable<T>
{
    void Sort(IComparer<T> comparer) 
    {
        if  (comparer.Compare(a, b) > 0) { ... }
    }
}
