Copy ( long source, long destination, int length ) : void	Copies a specified number of bytes to a new location
Dispose ( ) : void	Releases all the resources used by the BinaryStreamBase object.
Flush ( ) : void	When overridden in a derived class, clears all buffers for this stream and causes any buffered data to be written to the underlying device.
InsertBytes ( int numberOfBytes, int lengthOfValidDataToShift ) : void	Inserts a certain number of bytes into the stream, shifting valid data to the right. The stream's position remains unchanged. (ie. pointing to the beginning of the newly inserted bytes). Internally this fuction merely acomplishes an Array.Copy(stream,position,stream,position+numberOfBytes,lengthOfValidDataToShift) However, it's much more complicated than this. So this is a pretty useful function. The newly created space is uninitialized.
Read ( byte buffer, int offset, int count ) : int	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.
Read7BitUInt32 ( ) : uint	Reads from the underlying stream in little endian format. Advancing the position.
Read7BitUInt64 ( ) : ulong	Reads from the underlying stream in little endian format. Advancing the position.
ReadAll ( byte buffer, int length ) : void	Reads from the underlying stream in little endian format. Advancing the position.
ReadAll ( byte buffer, int position, int length ) : void	Reads all of the provided bytes. Will not return prematurely, but continue to execute a Read command until the entire length has been read.
ReadBoolean ( ) : bool	Reads from the underlying stream in little endian format. Advancing the position.
ReadBytes ( ) : byte[]	Reads from the underlying stream in little endian format. Advancing the position.

ReadUInt56 ( ) : ulong	Reads from the underlying stream in little endian format. Advancing the position.
ReadUInt64 ( ) : ulong	Reads from the underlying stream in little endian format. Advancing the position.
ReadUInt8 ( ) : byte	Reads from the underlying stream in little endian format. Advancing the position.
RemoveBytes ( int numberOfBytes, int lengthOfValidDataToShift ) : void	Removes a certain number of bytes from the stream, shifting valid data after this location to the left. The stream's position remains unchanged. (ie. pointing to where the data used to exist). Internally this fuction merely acomplishes an Array.Copy(stream,position+numberOfBytes,stream,position,lengthOfValidDataToShift) However, it's much more complicated than this. So this is a pretty useful function. The space at the end of the copy is uninitialized.
Seek ( long offset, SeekOrigin origin ) : long	When overridden in a derived class, sets the position within the current stream.
SetLength ( long value ) : void	When overridden in a derived class, sets the length of the current stream.
TryReadBytes ( int maxLength, byte &value ) : bool	Reads a byte array from the provided stream. If the size of the stream exceedes maxLength value is set to null and this function returns false. This method can be used to limit the byte size returned. Since an untrusted source could claim that the length is int.MaxValue, this prevents allocating 2GB of RAM to store the result.
TryReadString ( int maxLength, string &value ) : bool	Reads a string from the provided stream. If the size of the string exceedes maxLength value is set to null and this function returns false. This method can be used to limit the byte size returned. Since an untrusted source could claim that the length is int.MaxValue, this prevents allocating 2GB of RAM to store the result.
