Add Array to exsisting Json

[IronGarlic]

Hi,
i have a JSON like this
{
"Details":""
}

I want add an array to "Details", but i can't find an example to do that.

X:=TSuperObject.Create(JsonString);
item := TSuperObject.Create();
item.S['aaa'] := 'aaaaa';
item.I['bbb'] := 12345;
X.A['Details'].Add(item);

I guess you want to "Details" TO BE an array
so you'll get
{ "Details":[{"aaa":"aaaaa", "bbb":12345}] }

hi,
thanks for the quick response, btw how can i re-use the item?
Because there is not .clear .free or wat to destroy the object?

nono!
you've attached this to array and it'll be freed after use becuase it's an interface!
Arr:ISuperArray;
Item, X:ISuperObject;
instead you simply have to create a new item every time
