- buffer Byte
- The buffer to write the data into.
- offset Int32
- The byte offset in buffer at which to begin writing data from the stream.
- count Int32
- The maximum number of bytes to read.
- cancellationToken CancellationToken
- The token to monitor for cancellation requests. The default value is None.
TaskInt32A task that represents the asynchronous read operation. The value of the
TResult parameter contains the total number of bytes read into the buffer. The result value can be less than the number of bytes requested if the number of bytes currently available is less than the requested number, or it can be 0 (zero) if the end of the stream has been reached.
| ArgumentNullException | buffer is . |
| ArgumentOutOfRangeException | offset or count is negative. |
| ArgumentException | The sum of offset and count is larger than the buffer length. |
| NotSupportedException | The stream does not support reading. |
| ObjectDisposedException | The stream has been disposed. |
| InvalidOperationException | The stream is currently in use by a previous read operation. |
