Parameters
- item
- The object to locate. The value can be null for reference types.
- comparer
- The comparer implementation to use when comparing elements or null to use
the default comparer.
Return Value
The zero-based index of item in the sorted
ObjectSet, if
item is found; otherwise, a negative number, which is the bitwise complement of the index of the
next element that is larger than item or, if there is no larger element, the bitwise
complement of
Count.
Exceptions
