How to use C# BinaryReader Class

C# BinaryReader Object works at lower level of Streams. C# BinaryReader is using for read primitive types as binary values in a specific encoding stream. Binaryreader Object works with Stream Objects that provide access to the underlying bytes. For creating a BinaryReader Object , you have to first create a FileStream Object and then pass BinaryReader to the constructor method .

  FileStream readStream ;
  readStream = new FileStream("c:\\testBinary.dat", FileMode.Open);

BinaryReader readBinary = new BinaryReader(readStream);

The main advantages of Binary information is that stores files as Binary format is the best practice of space utilization.




using System;
using System.Windows.Forms;
using System.IO;
using System.Text;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            FileStream readStream ;
            string msg = null;
            try
            {
                readStream = new FileStream("c:\\csharp.net-informations.dat", FileMode.Open);
                BinaryReader readBinary = new BinaryReader(readStream);
                msg = readBinary.ReadString();
                MessageBox.Show(msg);
                readStream.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show (ex.ToString());
            }
        }
    }
}

BinaryWriter you can use in the same way to write as binary.
