Параметры
- buffer
- Тип: SystemByte
The buffer to write the data into. - offset
- Тип: SystemInt32
The byte offset in buffer at which to begin writing data from the stream. - count
- Тип: SystemInt32
The maximum number of bytes to read. - cancellationToken
- Тип: System.ThreadingCancellationToken

Возвращаемое значение
Тип:
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.
