Use the CanRead property to determine whether the current instance supports reading. Use the ReadAsync method to read asynchronously from the current stream.
The FileMode specifies how the operating system should open a file. If you go to the C# definition of FileMode, then you will see that it is an Enum with the following structure.
This method reads a maximum of buffer.Length bytes from the current file stream and stores them in buffer. The current position within the file stream is advanced by the number of bytes read; however, if an exception occurs, the current position within the file stream remains unchanged.
