How to use C# BinaryReader class?

If you want to read binary information from a stream, use the BinaryReader class.

The BinaryReader class is located in the System.IO namespace.

The following shows using the BinaryReader class to read from a file -

static void WriteMe() {
   using (BinaryWriter w = new BinaryWriter(File.Open("C:\abc.txt", FileMode.Create))) {
      w.Write(25.9);
      w.Write("DEMO DATA");
   }
}

static void ReadMe() {
   using (BinaryReader r = new BinaryReader(File.Open("C:\abc.txt", FileMode.Open))) {
      Console.WriteLine("Value : " + r.ReadDouble());
      Console.WriteLine("Value : " + r.ReadString());
   }
}

The above method is called in the Main() method -

static void Main(string[] args) {
   WriteMe();
   ReadMe();
   Console.ReadKey();
}
