' Imagine we have two separate JSON objects.

' Let's say we want to insert jsonB into jsonA to get this:

' {
'   "ciphertext": "encryptedData",
'   "status": 200,
'   "error": "errorMsg",
'   "users": [
'     {
'       "role": "Surgeon",
'       "sub_roles": [],
'       "viewable_for_sharing": true,
'       "eula_create_date": 1649108922482
'     },
'     {
'       "role": "Support",
'       "sub_roles": [
'         "Tech",
'         "Service"
'       ],
'       "viewable_for_sharing": true,
'       "eula_create_date": 1649108951523
'     }
'   ]
' }


' First add an empty array at the desired location (-1 means append to end).
jsonA.AddArrayAt(-1,"users")

' The destination is the empty "users" array, the source is the populated "users" array in jsonB.
Dim jsonUsersDest As Chilkat.JsonArray = jsonA.ArrayOf("users")
Dim jsonUsersSrc As Chilkat.JsonArray = jsonB.ArrayOf("users")
' Copy the array items from source to dest
jsonUsersDest.AppendArrayItems(jsonUsersSrc)



Debug.WriteLine(jsonA.Emit())

' The end result is this:

' {
'   "ciphertext": "encryptedData",
'   "status": 200,
'   "error": "errorMsg",
'   "users": [
'     {
'       "role": "Surgeon",

'     {
'       "role": "Support",
'       "sub_roles": [
'         "Tech",
