IsolatedStorageFileStream::EndRead Method (IAsyncResult^)

.NET Framework (current version)

Ends a pending asynchronous read request.

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

Syntax

public:
virtual int EndRead(
	IAsyncResult^ asyncResult
) override

Parameters

asyncResult: Type: System::IAsyncResult^
The pending asynchronous request.

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
ArgumentNullException	The asyncResult is null.

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.
