JSON valuePair entfernen

[Kostas]

Wie kann man bitte aus dem JSON "vatRate" entfernen?

Code:

{
  "price": {
    "dealerPriceGross": "535.50",
    "vatRate": "1.23",
    "currency": "EUR"
  }
}

Delphi-Quellcode:

procedure TForm1.Button1Click(Sender: TObject);
var aJSON: TJSonValue;
    aJSONStr:String;
begin
  aJSONStr := '{"price": { "dealerPriceGross": "535.50", "vatRate": "1.23", "currency": "EUR" }}';

  aJSON := TJSONObject.ParseJSONValue(aJSONStr);


end;
