This stream is sourced from a file, as in the examples.   There are discrete methods for reading individual primitive data type values, such as Bytes and Singles. You must catch the EndOfStreamException when using these discrete data types.   For the generic Read method, -1 is returned if the end of stream was encountered. For the array syntax Read methods, a count of 0 will be returned when the end of stream is encountered.   When reading from a Binary file, it is crucial that the formatting of data used by BinaryWriter be accurately recognised. Being 1 byte out of sequence can completely destroy the sequencing of the remaining file contents.  Syntax Constructor Create ( DataStream : System.IO.Stream ; ); Constructor Create ( DataStream : System.IO.Stream; DataEncoding : System.Text.Encoding );  Methods Close   Closes the BinaryReader PeekChar   Returns (peeks at) the next stream byte without updating stream position Read   Reads the next character or block of characters from the current stream ReadBoolean   Reads the next byte from the current stream as a Boolean ReadByte   Reads the next byte from the current stream ReadBytes   Reads the next block of bytes from the current stream ReadChar   Reads the next character from the current stream ReadChars   Reads the next block of characters from the current stream ReadDecimal   Reads the next 16 bytes from the current stream as a Decimal number ReadInt16   Reads the next 2 bytes from the current stream as an Int16 number ReadInt32   Reads the next 4 bytes from the current stream as an Int32 number ReadInt64   Reads the next 8 bytes from the current stream as an Int64 number ReadSByte   Reads the next signed byte from the current stream ReadSingle   Reads the next 16 bytes from the current stream as a Single number ReadString   Reads a string from the current stream ReadUInt16   Reads the next 2 bytes from the current stream as an UInt16 number ReadUInt32   Reads the next 4 bytes from the current stream as an UInt32 number ReadUInt64   Reads the next 8 bytes from the current stream as an UInt64 number  Properties BaseStream    Stream    Exposes access to the underlying stream of the BinaryReader  Microsoft MSDN links   System.IO System.IO.binaryreader
