[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Ends a pending asynchronous read request.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- asyncResult
- Type: System.IAsyncResult
The stream is closed or an internal error has occurred
Return Value
Type: System.Int32The 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.
| 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 Nothing. |
| InvalidOperationException | EndRead is called multiple times. |
| IOException | The stream is closed or an internal error has occurred. |
| ObjectDisposedException | The stream has been disposed. |
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.
