IStringMap.Keys

Syntax

Keys: ICollection;

Description

The Keys property returns collection of string map keys.

Example

Sub Main;

Var

StrMap: IStringMap;

i: Integer;

Keys: ICollection;

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;

Keys:=StrMap.Keys;

i:=Keys.Count;

End Sub Main;

After executing the example a string map is generated, elements with repeated keys are overwritten, and the "i" variable contains the number of keys.
