EndRead Method

SourceCode.IO Namespace > ProtectedStream Class : EndRead Method

Waits for the pending asynchronous read to complete. (Consider using System.IO.Stream.ReadAsync(System.Byte[],System.Int32,System.Int32) instead; see the Remarks section.)

Syntax

Visual Basic (Declaration)

Public Overrides Function EndRead( _
   ByVal asyncResult As IAsyncResult _
) As Integer

Visual Basic (Usage)

Dim instance As ProtectedStream
Dim asyncResult As IAsyncResult
Dim value As Integer
 
value = instance.EndRead(asyncResult)

C#

public override int EndRead( 
   IAsyncResult asyncResult
)

C++/CLI

public:
int EndRead( 
   IAsyncResult^ asyncResult
) override 

Parameters

asyncResult

The reference to the pending asynchronous request to finish.

Return Value

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.

Exceptions

Exception	Description
System.ArgumentNullException	asyncResult is null.
System.ArgumentException	A handle to the pending read operation is not available.-or-The pending operation does not support reading.
System.InvalidOperationException	asyncResult did not originate from a System.IO.Stream.BeginRead(System.Byte[],System.Int32,System.Int32,System.AsyncCallback,System.Object) method on the current stream.
System.IO.IOException	The stream is closed or an internal error has occurred.
