DeflateStream.EndRead(IAsyncResult) Method
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Waits for the pending asynchronous read to complete. (Consider using the ReadAsync(Byte[], Int32, Int32) method instead.)
public:
override int EndRead(IAsyncResult ^ asyncResult);public override int EndRead (IAsyncResult asyncResult);override this.EndRead : IAsyncResult -> intPublic Overrides Function EndRead (asyncResult As IAsyncResult) As IntegerParameters
- asyncResult
- IAsyncResult
The reference to the pending asynchronous request to finish.
Returns
The number of bytes read from the stream, between 0 (zero) and the number of bytes you requested. DeflateStream returns 0 only at the end of the stream; otherwise, it blocks until at least one byte is available.
Exceptions
asyncResult is null.
asyncResult did not originate from a BeginRead(Byte[], Int32, Int32, AsyncCallback, Object) method on the current stream.
An exception was thrown during a call to WaitOne().
The end call is invalid because asynchronous read operations for this stream are not yet complete.
-or-
The stream is null.
Remarks
Starting with .NET Framework 4.5, you can perform asynchronous read operations by using the ReadAsync method. The EndRead method is still available in current versions to support legacy code; however, you can implement asynchronous I/O operations more easily by using the new async methods. For more information, see Asynchronous File I/O.
Call this method to determine how many bytes were read from the stream. This method can be called once to return the amount of bytes read between calls to BeginRead and EndRead.
This method blocks until the I/O operation has completed.
