Comparer

Synopsis

The Comparer class is used to compare two objects of the same type. The Compare() method takes two objects. If the first object is less than the second, a negative value is returned. If the first object is greater than the second, a positive value is returned. If the objects are equal, zero is returned. The comparisons of strings are case-sensitive. For case insensitive string comparisons, use CaseInsensitiveComparer.
