dynamic multithreading c# return object list

Dear Dhruv,

Im using same one hotel api that return json data so i have using this multi threading.

public async Task> Availability(HotelSearch hotelSearch, List<string> hotels, string apikey, string endpoint, string endpointMethod, string session, string logpath)
{
List Response = new List();
var HotelsList = splitList(hotels); // We split 1000 hotel into 250
int NumberOfRequest = HotelsList.Count();
try
{
IEnumerablestring>> downloadTasksQuery =
from h in HotelsList select RequestAvail(hotelSearch, h, apikey, endpoint, endpointMethod, session, logpath);
Liststring>> downloadTasks = downloadTasksQuery.ToList();
var inventory = await Task.WhenAll(downloadTasks);
while (downloadTasks.Count > 0)
{
Task<string> firstFinishedTask = await Task.WhenAny(downloadTasks);
downloadTasks.Remove(firstFinishedTask);
string ResResult = await firstFinishedTask;
var response = JsonConvert.DeserializeObject(ResResult);
if (Response == null)
{
Response.Add(response);
}
else
{
if (response.hotels != null)
{
Response.Add(response);
}
}
}
}
catch (Exception ex)
{
ExceptionlessClient.Default.SubmitLog(typeof(AvailabilityRequest).FullName, ex.Message, "Trace");
}
return Response;
}

In above code "RequestAvail" is method where we making Async request to api.

This will hep you to make async with multipile many request at a time.

Thanks

Hey the below code may help you.
public List<string> DataFromDb()
{
    List<string> data = new List<string>
    {
        "Red", "Green", "Blue", "Yellow"
    };
    return data;
}

public async Taskstring>> GetData()
{
    try
    {
        return await Task.Run(() => DataFromDb());
    }
    catch (Exception e)
    {
        throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.InternalServerError)
        {
            Content = new StringContent("Error : " + e.Message),
            ReasonPhrase = "Critical Exception"
        });
    }
}

Mention api name and also what you want to achieve by multi threading
