IStringMap.Key

Syntax

Key(Index: Integer): String;

Parameters

Index - element index.

Description

The Key property returns key of the element, which index is passed by the Index parameter.

Example

Sub Main;

Var

StrMap: IStringMap;

i: Integer;

s: String;

Begin

StrMap:=New StringMap.Create;

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

StrMap.Add("Key_"+Math.RandBetweenI(0,100).ToString ,"Value "+Math.RandBetweenI(0,100).ToString);

End For;

s:=StrMap.Key(StrMap.Count-1);;

End Sub Main;

After executing the example a map of strings is generated, elements with repeated keys are overwritten, and the "s" variable contains key of the last element.
