DigitalMultiChannelReader.EndReadSingleSamplePortInt16 Method
Handles the end of an asynchronous read initiated with BeginReadSingleSamplePortInt16(AsyncCallback, Object) and retrieves the read samples.

Namespace:  NationalInstruments.DAQmx
Assembly:  NationalInstruments.DAQmx (in NationalInstruments.DAQmx.dll) Version: 20.7.40.49302

Syntax

public short[] EndReadSingleSamplePortInt16(
	IAsyncResult asyncResult
)
Public Function EndReadSingleSamplePortInt16 ( 
	asyncResult As IAsyncResult
) As Short()

Parameters

asyncResult
Type: SystemIAsyncResult
An IAsyncResult that represents an asynchronous call started by calling BeginReadSingleSamplePortInt16(AsyncCallback, Object).

Return Value

Type: Int16
A 1D array of 16-bit integer samples from the task. Each element in the array corresponds to a channel in the task. The order of the channels in the array corresponds to the order in which you add the channels to the task or to the order of the channels you specify in ChannelsToRead.

Exceptions

ExceptionCondition
ArgumentExceptionasyncResult is or is not an instance of IAsyncResult returned from a call to BeginReadSingleSamplePortInt16(AsyncCallback, Object).
DaqExceptionThe NI-DAQmx driver returned an error during the asynchronous operation.
OutOfMemoryExceptionThere is not enough memory to carry out this operation.

Remarks

If you call EndReadSingleSamplePortInt16(IAsyncResult) before the asynchronous read represented by the provided IAsyncResult is complete, EndReadSingleSamplePortInt16(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.
