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

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();}

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();}

BinaryReader

Remarks

BinaryReader does not restore the file position after an unsuccessful read.

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
