Parameters

buffer  Byte
An array of bytes. When this method returns, the buffer contains the specified byte array with the values between offset and (offset + count - 1) replaced by the bytes read from the current source.
offset  Int32
The zero-based byte offset in buffer at which to begin storing the data read from the current stream.
count  Int32
The maximum number of bytes to be read from the current stream.

Return Value

Int32
The total number of bytes read into the buffer. This can be less than the number of bytes requested if that many bytes are not currently available, or zero (0) if the end of the stream has been reached.
