Parameters

buffer
Type: 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
Type: int

The zero-based byte offset in buffer at which to begin storing the data read from the current stream.

count
Type: int

The maximum number of bytes to be read from the current stream.

Return Value

Type: int

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.

Exception type Condition

ArgumentNullException

buffer is null reference (Nothing in Visual Basic).

ArgumentOutOfRangeException

offset or count is negative.

IOException

An I/O error occurs.

ObjectDisposedException

Methods were called after the stream was closed.

NotSupportedException

The stream does not support reading.

ArgumentException

The sum of offset and count is larger than the buffer length.
