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
- asyncResult
Type: System.IAsyncResult
The stream is closed or an internal error has occurred
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.
