Store Array of Record in JSON - json

Question

How can an array of record be stored in JSON via SuperObject library. For example..
type
TData = record
str: string;
int: Integer;
bool: Boolean;
flt: Double;
end;
var
DataArray: Array[0..100] of TData;

Answer 1

Just use the superobject Marshalling TSuperRTTIContext
program Project1;
{$APPTYPE CONSOLE}
{$R *.res}
uses
superobject,
System.SysUtils;
type
TData = record
str : string;
int : Integer;
bool : Boolean;
flt : Double;
end;
TDataArray = Array [0 .. 100] of TData;
procedure Test;
var
DataArray : TDataArray;
so : ISuperObject;
ctx : TSuperRttiContext;
begin
ctx := TSuperRttiContext.Create;
try
so := ctx.AsJson<TDataArray>( DataArray );
finally
ctx.Free;
end;
Writeln( so.AsJson );
end;
begin
try
Test;
except
on E : Exception do
Writeln( E.ClassName, ': ', E.Message );
end;
ReadLn;
end.

Make it a string first.
Your array:
//Array[0] := 'Apple';
//Array[1] := 'Orange';
//Array[2] := 'Banana';
myArrayAsStr := '"MyArray": [{ "1": "' + Array[0] +'", "2": "' + Array[1] +'"}';
Then you can just make it into JSON with SO(myArrayAsStr)
You can always generate your array as string in a different procedure but I think thats the way to do it.
Ill keep checking if there is an easier way ;)
EDIT:
SuperObject also has the following function:
function SA(const Args: array of const): ISuperObject; overload;
You will be able to convert that to a string again and add it in the total JSON string.
