IHashtable.ContainsKey

Syntax

ContainsKey(Key: Variant): Boolean;

Parameters

Key. Element key.

Description

The ContainsKey method checks if the element with the Key key exists.

Example

Sub Main;

Var

Hash: IHashtable;

i: Integer;

s: String;

Begin

Hash:=New Hashtable.Create;

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

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

End For;

If Hash.ContainsKey("Key_"+Math.RandBetweenI(0,Hash.Count).ToString) Then

s:="Yes";
