I have the following two functions, their only difference is the type that it returns. is there any simple way to combine these two functions into a single function and pass the data type as a parameter?

        public List<CCG_OrderData> getCCG_ItemData(string url)
        {
            string jsonData = AddBracketsToJsonString(getJsonData(url));
            return JsonConvert.DeserializeObject<List<CCG_OrderData>>(jsonData);
        }

        public List<CCG_ReceivedOrders> getCCG_ItemData2(string url)
        {
            string jsonData = AddBracketsToJsonString(getJsonData(url));
            return JsonConvert.DeserializeObject<List<CCG_ReceivedOrders>>(jsonData);
        }

You can make a generic method:

public List<T> getCCG_ItemData<T>(string url)
{
    string jsonData = AddBracketsToJsonString(getJsonData(url));
    return JsonConvert.DeserializeObject<List<T>>(jsonData);
}

Open in new window


Then it's simply a matter of calling the method with the correct type argument:

CCG_OrderData a = getCCG_ItemData<CCG_OrderData>("www.example.com");
CCG_ReceivedOrders b = getCCG_ItemData<CCG_ReceivedOrders>("www.example.com");

If both CCG_OrderData and CCG_ReceivedOrders had a common class they inherit from then you could use casting BUT the generic method suggested by kaufmed above is neater.

ps.  If you look closely you will see JsonConvert.DeserializeObject that you use is using the same, generic, technique.
