Method BeginRead

Namespace: MongoDB.Driver.GridFS

Assembly: MongoDB.Driver.dll

BeginRead(byte[], int, int, AsyncCallback, object)

Begins an asynchronous read operation. (Consider using ReadAsync(byte[], int, int) instead.)

public override IAsyncResult BeginRead(byte[] buffer, int offset, int count, AsyncCallback callback, object state)

Parameters

buffer byte[]: The buffer to read the data into.
offset int: The byte offset in buffer at which to begin writing data read from the stream.
count int: The maximum number of bytes to read.
callback AsyncCallback: An optional asynchronous callback, to be called when the read is complete.
state object: A user-provided object that distinguishes this particular asynchronous read request from other requests.

Returns

IAsyncResult: An IAsyncResult that represents the asynchronous read, which could still be pending.

Exceptions

IOException: Attempted an asynchronous read past the end of the stream, or a disk error occurs.
ArgumentException: One or more of the arguments is invalid.
ObjectDisposedException: Methods were called after the stream was closed.
NotSupportedException: The current Stream implementation does not support the read operation.
