How to get AnalogWaveform from AnalogWaveformCollection in C#.NET?

[Penny]

Hi there,

I have a VS2008 C#.NET application based on NI examples that is continously streaming an AnalogWaveformCollection to file (hooray!) from both channels of my USB 5132 .   Now I want to read the file back in and look at the voltages.  My question is:  If I am reading in the file as 

AnalogWaveformCollection<int>[] records = binaryFormatter.Deserialize(fileStream) as AnalogWaveformCollection<int>[];

 how can I access the AnalogWaveform part of the AnalogWaveformCollection structure?  I want to send the AnalogWaveforms to the NI routine PlotRecords() as in

        private AnalogWaveform<double>[] ScaleRecords(AnalogWaveform<int>[] records)
        {
          
            AnalogWaveform<double>[] scaledRecords = new AnalogWaveform<double>[records.Length];
            for (int i = 0; i < records.Length; ++i)
            {
                scaledRecords[i] = AnalogWaveform<double>.FromArray1D(records[i].GetScaledData());
            }

            return scaledRecords;
        }

I have looked at the definition of AnalogWaveformCollection, below, but do not understand how to unpack any of its components.  Any thoughts would be appreciated.  Even one example of one component would help.

Thanks,

Penny

Hi,

All set.  Figured it out by looking at the C# example ConfiguredAcquisition. 

Thanks,
