Stream. End Read(IAsyncResult) Method
Waits for the pending asynchronous read to complete. (Consider using the ReadAsync(Byte, Int32, Int32) method instead.)
public: override int EndRead(IAsyncResult ^ async_result);
public override int EndRead (IAsyncResult async_result);
override this.EndRead : IAsyncResult -> int
Public Overrides Function EndRead (async_result As IAsyncResult) As Integer
The reference to the pending asynchronous request to finish.
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.
asyncResult did not originate from a BeginRead(Byte, Int32, Int32, AsyncCallback, Object) method on the current stream.
The end call is invalid because asynchronous read operations for this stream are not yet complete.
The stream is
Starting with the .NET Framework 4.5, you can perform asynchronous read operations by using the ReadAsync method. The EndRead method is still available in the .NET Framework 4.5 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.
This method blocks until the I/O operation has completed.
