numBytesToRead should be 0 now, and numBytesRead shouldĬonsole::WriteLine("number of bytes read: ", numBytesRead) Int n = s->Read(bytes, numBytesRead, 10) Read may return anything from 0 to 10. The following example shows how to use Read to read a block of data. Methods were called after the stream was closed. Use BinaryReader for reading primitive data types. An implementation is free to return fewer bytes than requested even if the end of the stream has not been reached. Read returns 0 only when there is no more data in the stream and no more is expected (such as a closed socket or end of file). The implementation will block until at least one byte of data can be read, in the event that no data is available. Implementations return the number of bytes read. The current position within the stream is advanced by the number of bytes read however, if an exception occurs, the current position within the stream remains unchanged. Implementations of this method read a maximum of buffer.Length bytes from the current stream and store them in buffer. Use the ReadAsync method to read asynchronously from the current stream. Use the CanRead property to determine whether the current instance supports reading. This can be less than the number of bytes allocated in the buffer if that many bytes are not currently available, or zero (0) if the end of the stream has been reached. The total number of bytes read into the buffer. When this method returns, the contents of this region are replaced by the bytes read from the current source.
