Handles the end of an asynchronous read initiated with BeginReadMultiSamplePortUInt16(Int32, AsyncCallback, Object) and retrieves the read samples.

Namespace: NationalInstruments.DAQmx
Assembly: NationalInstruments.DAQmx (in NationalInstruments.DAQmx.dll) Version: 20.7.45.49302

Syntax

public ushort[] EndReadMultiSamplePortUInt16(
	IAsyncResult asyncResult
)

Public Function EndReadMultiSamplePortUInt16 ( 
	asyncResult As IAsyncResult
) As UShort()

Parameters

asyncResult: Type: SystemIAsyncResult
An IAsyncResult that represents an asynchronous call started by calling BeginReadMultiSamplePortUInt16(Int32, AsyncCallback, Object).

Return Value

Type: UInt16
A 1D array of 16-bit unsigned integer samples from the task. Each element in 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 BeginReadMultiSamplePortUInt16(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 EndReadMultiSamplePortUInt16(IAsyncResult) before the asynchronous read represented by the provided IAsyncResult is complete, EndReadMultiSamplePortUInt16(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.

Note
Refer to Asynchronous Reads and Writes for additional information.
