EndRead Method

Stream.EndRead Method

Waits for the pending asynchronous read to complete.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

public virtual int EndRead(
	IAsyncResult asyncResult


Type: System.IAsyncResult
The reference to the pending asynchronous request to finish.

Return Value

Type: System.Int32
The number of bytes read from the stream, between zero (0) and the number of bytes you requested. Streams return zero (0) only at the end of the stream, otherwise, they should block until at least one byte is available.


asyncResult is null.


asyncResult did not originate from a BeginRead method on the current stream.


The stream is closed or an internal error has occurred.

Call EndRead to determine how many bytes were read from the stream.

EndRead can be called once on every IAsyncResult from BeginRead.

This method blocks until the I/O operation has completed.
