CsharpProgrammingServer Side Programming

If you want to write binary information into the stream, then use the BinaryWriter class in C#. You can find it under the System.IO namespace.

The following is the implementation of the BinaryWriter class −

static void WriteMe() {
   using (BinaryWriter w = new BinaryWriter(File.Open("C:\\abc.txt", FileMode.Create))) {
      w.Write(37.8);
      w.Write("test”);
   }
}

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());
   }
}

Above, theBinaryWriter class opens a file and writes content into it −

static void WriteMe() {
   using (BinaryWriter w = new BinaryWriter(File.Open("C:\\abc.txt", FileMode.Create))) {

      w.Write(37.8);
      w.Write("test");
   }
}
