Parameters
-
buffer
- Type:
array<
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:
Int32
The zero-based byte offset in buffer at which to begin
storing the data read from the current stream.
-
count
- Type:
Int32
The maximum number of bytes to be read from the current
stream.
Return Value
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.
Exceptions

|
ArgumentOutOfRangeException
|
Thrown when the offset or count is negative. |
