LastIndexOfPos(Value: String; StartIndex: Integer): Integer;
Value. Element value that should be found.
StartIndex. Index of the element, from which search is executed.
The LastIndexOfPos method reversely searches for the value, starting from the StartIndex index.
The method returns index of the first found element in case of successful search, otherwise it returns -1.
Sub Main;
Var
StrL: IStringList;
i: Integer;
Begin
StrL:=New StringList.Create;
For i:=0 To Math.RandBetweenI(50,100) Do
StrL.Add("Number "+Math.RandBetweenI(0,100).ToString);
End For;
i:=StrL.LastIndexOfPos("Number 25",Double.FloorInt(StrL.Count/2));
End Sub Main;
After executing the example a dynamic array of strings is generated, and reverse search of the Number 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.
