IsolatedStorageFileStream.EndRead Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Ends a pending asynchronous read request.

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

Syntax

'Declaration
Public Overrides Function EndRead ( _
    asyncResult As IAsyncResult _
) As Integer

public override int EndRead(
    IAsyncResult asyncResult
)

Parameters

Return Value

Type: System.Int32
The number of bytes read from the stream, between zero and the number of requested bytes. Streams will only return zero at the end of the stream. Otherwise, they will block until at least one byte is available.

Exceptions

Exception Condition
IsolatedStorageException

The isolated store has been removed.

-or-

Isolated storage is disabled.
ArgumentException

asyncResult was not created by calling BeginRead on this class.
ArgumentNullException

asyncResult is nulla null reference (Nothing in Visual Basic).
InvalidOperationException

EndRead is called multiple times.
IOException

The stream is closed or an internal error has occurred.
ObjectDisposedException

The stream has been disposed.

Remarks

EndRead must be called exactly once on every IAsyncResult object from BeginRead, and calling EndRead is the only way to know how many bytes were read from the Stream. EndRead will block until the I/O operation has completed.
