// Batch 1 File
string a1 = "{\"payload\": {\"Orders\": [{\"AmazonOrderId\": \"1\",\"OrderStatus\": \"Unshipped\"},{\"AmazonOrderId\": \"2\",\"OrderStatus\": \"Unshipped\"}]}";

// Batch 2 File
string a2 = "{\"payload\": {\"Orders\": [{\"AmazonOrderId\": \"3\",\"OrderStatus\": \"Unshipped\"},{\"AmazonOrderId\": \"4\",\"OrderStatus\": \"Unshipped\"}]}";

// Required Merged File
// {"payload": {"Orders": [{"AmazonOrderId": "1","OrderStatus": "Unshipped"},{"AmazonOrderId": "2","OrderStatus": "Unshipped"},{"AmazonOrderId": "3","OrderStatus": "Unshipped"},{"AmazonOrderId": "4","OrderStatus": "Unshipped"}]}

bool success = true;
Chilkat.JsonObject json1 = new Chilkat.JsonObject();

Chilkat.JsonObject json2 = new Chilkat.JsonObject();

// We're going to add the order records from json2 to json1.
Chilkat.JsonArray jarr1 = json1.ArrayOf("payload.Orders");

int i = 0;
int numOrders = jarr2.Size;

// Show the merged JSON.
