Hi @huachong.li

You have to use .NET API.

You can follow this .NET API tutorial.

Here is the sample request code:

request = timeSeries.SetupDataRequest("31283H5T8=RRPS")
     .WithView("NDA_RAW")
     .WithAllFields()
     .WithInterval(CommonInterval.Daily)
     .WithNumberOfPoints(10)
     .OnDataReceived(DataReceivedCallback)
     .OnStatusUpdated(StatusUpdatedCallback)
     .CreateAndSend();

Here is the sample DataReceivedCallback code:

foreach (IData data in chunk.Records.ToList())
 {
     object closeObject;
     DateTime? date = null;
     double? ask = null;
     if (data.TryGetValue("NDA_DATE", out closeObject))
         date = (DateTime)closeObject;
     if (data.TryGetValue("NDA_ASK_PRICE", out closeObject))
         ask = (double)closeObject;
     Console.WriteLine(date + " " + ask);
 }

This is the output:
