Saving and reading data in Binary Format

Question

Hello

I am developing a Firebase supported project. What I want to do is to take the current data and keep it in a file in Binary format so that it cannot be read easily. I thought of such a method because the data does not contain very sensitive data. I think I should use BinaryWriter and BinaryReader classes for this. However, before I put it into code, I would like to get your opinion. How can I go about this? What would be your suggestions for me?

Thanks.

Hi @fatih uyanık , Welcome to Microsoft Q&A,

First of all, Q&A does not provide support for third-party products such as Firebase. It is assumed that you already have code for Firebase data.

1. Use BinaryWriter to write data to a file.
2. Use BinaryReader to read data from a file.

using System;
using System.IO;
using System.Threading.Tasks;
using Firebase.Database;
using Firebase.Database.Query;

public class FirebaseBinaryExample
{
    private static readonly string FirebaseUrl = "https://your-firebase-url.firebaseio.com/";
    private static readonly string FirebaseSecret = "your-firebase-secret";

    public static async Task Main(string[] args)
    {
        var firebaseClient = new FirebaseClient(
            FirebaseUrl,
            new FirebaseOptions
            {
                AuthTokenAsyncFactory = () => Task.FromResult(FirebaseSecret)
            });

        //retrieve data
        var data = await firebaseClient
            .Child("path/to/your/data")
            .OnceAsync<MyDataType>();

        // Writing binary files
        using (FileStream fs = new FileStream("data.bin", FileMode.Create))
        using (BinaryWriter writer = new BinaryWriter(fs))
        {
            foreach (var item in data)
            {
                // Assume MyDataType has properties Id and Name
                writer.Write(item.Object.Id);
                writer.Write(item.Object.Name);
            }
        }

        //Reading binary files
        using (FileStream fs = new FileStream("data.bin", FileMode.Open))
        using (BinaryReader reader = new BinaryReader(fs))
        {
            while (fs.Position < fs.Length)
            {
                int id = reader.ReadInt32();
                string name = reader.ReadString();
                Console.WriteLine($"Id: {id}, Name: {name}");
            }
        }
    }

    public class MyDataType
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }
}

Best Regards,
