Transcript

  • 1. BinaryWriter and BinaryReader Jason
  • 2. BinaryWriter  Writes primitive types in binary to a stream and supports writing strings in a specific encoding.  BinaryWriter()  BinaryWriter(Stream)  BinaryWriter(Stream, Encoding)  BinaryWriter(Stream, Encoding, Boolean)
  • 3. BinaryWriter  Methods Write(Boolean) Write(Byte) Write(Byte[]) Write(Char) Write(Char[]) Write(Decimal) Write(Double) Write(Int16) Write(Int32) Write(Int64) Write(SByte) Write(Single) Write(String) Write(UInt16) Write(UInt32) Write(UInt64) Write(Byte[], Int32, Int32) Write(Char[], Int32, Int32)
  • 4. BinaryReader  Reads primitive data types as binary values in a specific encoding.  BinaryReader(Stream)  BinaryReader(Stream, Encoding)  BinaryReader(Stream, Encoding, Boolean)
  • 5. BinaryReader  Methods Read() ReadBoolean ReadByte ReadBytes ReadChar ReadChars ReadDecimal ReadDouble ReadInt16 ReadInt32 ReadInt64 ReadSByte ReadSingle ReadString ReadUInt16 ReadUInt32 Read(Char[], Int32, Int32) Read(Byte[], Int32, Int32)
  • 6. BinaryReader  example using (var writer = new BinaryWriter(File.Open(fileName, FileMode.Create))) { writer.Write(10); } using (var reader = new BinaryReader(File.Open(fileName, FileMode.Open))) { reader.ReadInt32(); reader.ReadBytes(); } reader.ReadInt32() Answer: 10 reader.ReadBytes() Answer:
  • 7. BinaryReader  example using (var writer = new BinaryWriter(File.Open(fileName, FileMode.Create))) { writer.Write(“Jason”); } using (var reader = new BinaryReader(File.Open(fileName, FileMode.Open))) { reader.ReadString(); reader.ReadBytes(); } reader.ReadString() Answer: Jason reader.ReadBytes() Answer:
  • 8. BinaryWriter and BinaryReader  example using (var writer = new BinaryWriter(File.Open(fileName, FileMode.Create))) { writer.Write(1.250F); writer.Write(@"c:Temp"); writer.Write(10); writer.Write(true); } using (var reader = new BinaryReader(File.Open(fileName, FileMode.Open))) { var aspectRatio = reader.ReadSingle(); var tempDirectory = reader.ReadString(); var autoSaveTime = reader.ReadInt32(); var showStatusBar = reader.ReadBoolean(); }
  • 9. BinaryReader  Remarks  BinaryReader does not restore the file position after an unsuccessful read.
  • 10. BinaryReader VS StreamReader  If the entirety of your data is a straightforward binary encoding of text data, use StreamReader.  If you've fundamentally got binary data which may happen to have some portions in text, use BinaryReader
  • 11. Reference  File and Stream I/O  http://msdn.microsoft.com/en-us/library/k3352a4t(v=vs.110).aspx  BinaryReader  http://msdn.microsoft.com/en-us/library/system.io.binaryreader(v=vs.110).aspx  BinaryWriter  http://msdn.microsoft.com/en-us/library/gg712841(v=vs.110).aspx
