IndexOfPos(Value: Variant; StartIndex: Integer): Integer;
Value. Element value that should be found.
StartIndex. Element index, starting from which the search is executed.
The IndexOfPos method directly searches for value according to the specified parameters.
The method returns element index in case of successful search, and -1 if the value is not found.
Sub UserProc;
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.IndexOfPos(25, Double.FloorInt(ArrayL.Count / 2));
End Sub UserProc;
After executing the example a dynamic array of random integer numbers is generated, and direct search of the 25 value is executed in the second part of the array. The "i" variable contains the number of the first found element in case of successful search.
