extends Comparable comparer); Return Value: If the item founds, then this method returns the zero-based index of the element to be searched for and if not found, then a negative number that 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. Binary search is the process of finding a value in a list of values with O(log n). Already have an account? □_\square□​. Simple question - given an IList how do you perform a binary search without writing the method yourself and without copying the data to a type with build-in binary search support. If the target value is greater than the middle element, eliminate all the elements to the left of (and including) the middle element from the search, and return to step one with this smaller search space. This method searches the list for the specified key using a binary search algorithm and returns the index of the key if it is found in the list. BinarySearch (Int32, Int32, T, IComparer) Searches a range of elements in the sorted List for an element using the specified comparer and returns the zero-based index of the element.
