ProcessQueueTBinarySearch(Int32, Int32, T, IComparerT) Method

Searches a range of elements in the sorted ProcessQueueT, using a binary search algorithm, for an element using the specified comparer and returns the zero-based index of the element.

function BinarySearch(index, count, item, comparer);

Parameters

index Int32: The zero-based starting index of the range to search.
count Int32: The length of the range to search.
item T: The object to locate. The value can be null for reference types.
comparer IComparerT: The Generic.IComparer implementation to use when comparing elements -or- null to use the default comparer: Generic.Comparer(Of T).Default

Return Value

Int32
The zero-based index of item in the sorted ProcessQueueT, if item is found; otherwise, 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.

Remarks

ProcessQueueT must be sorted in order for this function to return an accurate result.

Exceptions

ArgumentOutOfRangeException	startIndex is outside the range of valid indexes for the ProcessQueueT -or- count is less than 0 -or- startIndex and count do not specify a valid section in the ProcessQueueT
InvalidOperationException	The default comparer, Generic.Comparer.Default, cannot find an implementation of the IComparable generic interface or the IComparable interface for type T.
