Sample program to know use of Binary Reader and writer

Hi All..
The below code explains the use of binary reader and binary writer.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace UseOfBinaryReaderAndwriter
{
    class Program
    {
        static void Main(string[] args)
        {
            BinaryWriter bwObj;
            BinaryReader brObj;
            int i = 30;
            double d = 4.567;
            bool b = true;
            string s = "GudMorning Prime";
            try
            {
                bwObj=new BinaryWriter(new FileStream("Manikumar", FileMode.Create));
            }
            catch (IOException e)
            {
                Console.WriteLine(e.Message + "\n File Cannot Create..");
                return;
            }
            try
            {
                bwObj.Write(i);
                bwObj.Write(d);
                bwObj.Write(b);
                bwObj.Write(s);
            }
            catch(IOException e)
            {
                Console.WriteLine(e.Message + "\nCan not write to file");
                return;
            }
            bwObj.Close();
            try
            {
                brObj = new BinaryReader(new FileStream("manikumar", FileMode.Open));
            }
            catch (IOException e)
            {
                Console.WriteLine(e.Message + "\n Cannot open the file");
                return;
            }
            try
            {
                i = brObj.ReadInt32();
                Console.WriteLine("Integer Data = {0}", i);
                d = brObj.ReadDouble();
                Console.WriteLine("Double Data = {0}", d);
                b = brObj.ReadBoolean();
                Console.WriteLine("Boolean Data = {0}", b);
                s = brObj.ReadString();
                Console.WriteLine("String is = {0}", s);
            }
            catch (IOException e)
            {
                Console.WriteLine(e.Message + "\ncannot read the file");
                return;
            }
            brObj.Close();
            Console.ReadKey();
        }
    }
}

Thank You...
