C# Program to Implement BinaryReader

Code:

using System;
using System.IO;
class ConsoleApplication
{
    const string fileName = "program.dat";
    static void Main()
    {
        Write();
        Console.WriteLine("Using Binary Writer Class the Contents are Written ");
        Display();
    }
    public static void Write()
    {
        using (BinaryWriter writer = new BinaryWriter(File.Open(fileName, FileMode.Create)))
        {
            writer.Write(1.250F);
            writer.Write(@"C:\Temp");
        }
    }
    public static void Display()
    {
        float aspectRatio;
        string tempDirectory;
        if (File.Exists(fileName))
        {
            using (BinaryReader reader = new BinaryReader(File.Open(fileName, FileMode.Open)))
            {
                aspectRatio = reader.ReadSingle();
                tempDirectory = reader.ReadString();
            }
            Console.WriteLine("Aspect Ratio Set to : " + aspectRatio);
            Console.WriteLine("Temp Directory is : " + tempDirectory);
            Console.Read();
        }
    }
}


Output:

Using Binary Writer Class the Contents are Written 
Aspect Ratio set to : 1.25
Temp Directory is : C:\Temp
