IArrayList.IndexOfRange

Syntax

IndexOfRange(Value: Variant; StartIndex: Integer; Count: Integer): Integer;

Parameters

Value. Element value that should be found.

StartIndex. Element index, starting from which the search is executed.

Count. Number of elements in the range, in which the search is executed.

Description

The IndexOfRange method directly searches for element in the range and returns index of the found element in case of successful search, otherwise it returns -1.

Comments

The range starts from the element with the StartIndex index and contains Count of elements.

Example

Sub Main;

Var

ArrayL: IArrayList;

i: Integer;

Begin

ArrayL:=New ArrayList.Create;

For i:=0 To Math.RandBetweenI(50,100) Do

ArrayL.Add(Math.RandBetweenI(0,100));

End For;

i:=ArrayL.IndexOfRange(25,10,ArrayL.Count-20);

End Sub Main;

After executing the example a dynamic array of random numbers is generated, and direct search of the 25 value is executed in the whole array, except for the first and last 10 elements. In case of successful search, the "is" variable contains index of the found element.
