Insert value dynamically in Json object in existing key

Question

**Below code output**: I am able to get json as below by this code

 

{

"ContainerId": "848dc1ca-04ae-457e-b6ac-0dee454816c4",

"ContainerName": "Container1"

}

 

**Needed Output**: But I want to insert value dynamically like below json in array that contains multiple container ID and Container Name

 

I have to make json like this

{

                 "ContainerId": ["848dc1ca-04ae-457e-b6ac-0dee454816c4",

                                        "aj8dc1ca-04ae-457e-b6ac-0dee454816c4"],

                  "ContainerName": ["Container1","Container2"]

}

 

This is the code which for reference, Please let me know how I can do this in C#

 

 

var jsonDiaptchObject = JObject.Parse(stockItem.Payload);

var oldDispatchItem = await _stockItemService.GetStockItemFor(stockItem.Identifier);

foreach (var dispatchItem in packItemRequest.DispatchItems)

{

containerid = Guid.NewGuid();

KeyValuePair<string, string>[] propertyDispatchs = new KeyValuePair<string, string>[]

{

        new KeyValuePair<string, string>("ContainerId", containerid.ToString()),

        new KeyValuePair<string, string>("ContainerName",           dispatchItem.Container.ToString())

};

 

string olddispatchValue = null;

foreach (var propertyDispatch in propertyDispatchs)

{

if (jsonDiaptchObject.ContainsKey(propertyDispatch.Key))

{

              olddispatchValue = JObject.Parse(stockItem.Payload)     [propertyDispatch.Key]?.ToString(); 

//jsonDiaptchObject.Add(propertyDispatch.Key.Insert(0, propertyDispatch.Value));

}

       jsonDiaptchObject.Add(propertyDispatch.Key, propertyDispatch.Value);

}

}

stockItem.Payload = jsonDiaptchObject.ToString();
