Stream.Read Method (Byte, Int32, Int32)
When overridden in a derived class, reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read.
Assembly: mscorlib (in mscorlib.dll)
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.
The zero-based byte offset in buffer at which to begin storing the data read from the current stream.
The maximum number of bytes to be read from the current stream.
Return ValueType: System.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.
The sum of offset and count is larger than the buffer length.
buffer is null.
offset or count is negative.
An I/O error occurs.
The stream does not support reading.
Methods were called after the stream was closed.
Implementations of this method read a maximum of count bytes from the current stream and store them in buffer beginning at offset. 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 return the number of bytes read. The implementation will block until at least one byte of data can be read, in the event that no data is available.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). An implementation is free to return fewer bytes than requested even if the end of the stream has not been reached.
Use BinaryReader for reading primitive data types.
