CounterSingleChannelReaderEndReadMultiSampleUInt32 Method
Handles the end of an asynchronous read initiated with BeginReadMultiSampleUInt32(Int32, AsyncCallback, Object) and retrieves the read samples.
Namespace: NationalInstruments.DAQmx
Assembly: NationalInstruments.DAQmx (in NationalInstruments.DAQmx.dll) Version: 20.7.40.49302
Syntax
public uint[] EndReadMultiSampleUInt32( IAsyncResult asyncResult )
Public Function EndReadMultiSampleUInt32 ( asyncResult As IAsyncResult ) As UInteger()
Parameters
- asyncResult
- Type: SystemIAsyncResult
An IAsyncResult that represents an asynchronous call started by calling BeginReadMultiSampleUInt32(Int32, AsyncCallback, Object).
Return Value
Type: UInt32A 1D array of UInt32 samples from the task. Each element of the array corresponds to a sample from the task.
Exceptions
| Exception | Condition |
|---|---|
| ArgumentException | asyncResult is or is not an instance of IAsyncResult returned from a call to BeginReadMultiSampleUInt32(Int32, AsyncCallback, Object). |
| DaqException | The NI-DAQmx driver returned an error during the asynchronous operation. |
| OutOfMemoryException | There is not enough memory to carry out this operation. |
Remarks
If you call EndReadMultiSampleUInt32(IAsyncResult) before the asynchronous read represented by the provided IAsyncResult is complete, EndReadMultiSampleUInt32(IAsyncResult) waits for the read to complete before returning.
NI-DAQmx read and write methods time out after the amount of time specified by the Timeout property on the task you are reading from or writing to.
