) As Boolean
[C#]
public virtual bool ContainsKey(
   object key
);

   Object* key
);
[JScript]
public function ContainsKey(
   key : Object
) : Boolean;

Return Value

Exceptions

Exception Type Condition

This method can be overridden by a derived class.

This method uses a binary search algorithm; therefore, the average execution time is proportional to Log2 (size), where size is the size of the SortedList.This method behaves exactly as Contains.
