IStringMap.Key

Syntax

Key(Index: Integer): String;

Parameters

Index. Element index.

Description

The Key property returns key of the element with the specified index.

Example

Sub UserProc;
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 UserProc;

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