it will call TypeConverter.ConvertTo() to convert it back into object. Am I right ?

class DateTimeComparer : IComparer
{
    // IComparer implementation
    public int Comparer(object d1, object d2)
    {
        if ((d1 is DateTime) && (d2 is DateTime))
        {
            return DateTime.Compare(d1, d2);
        }
        else
        {
            throw new ArgumentException("Object(s) not of type System.DateTime");
        }
    }
