Thanks! I did it. But how could I save to the same file more than one variable?

Put them in a class and save that.

But I have more objects with that variable. I want to save for every object their variable in new line, also how could I then read it from file.

So you'd make an array of them and save that perhaps. I'd need a bit more detail about what you are trying to do - I'm kinda guessing at the moment.

The principle is to create an in memory class which holds all of the items you want and save it.

However, you can just call Serialize and Deserialize multiple times on the same file and it will append the next object to the output or read it from the input.

Are you trying to create it twice then? You need to have closed the previous one first.

What I am suggesting is:

Create the file
Write each thing to it by using BinaryFormatter.Serialize in a for loop or creating a single class and writing that
Close the file

If you're already working with a byte array, you can just do this:

 using System;
 using System.IO;
 
 FileStream fs = File.Create( Path.Combine( Application.persistentDataPath, "file.dat") );
 fs.Write( byteArray, 0, bytes.Length );        
 fs.Close( );

Then, you can read the bytes back in a similar way:

 FileStream fs = new FileStream( Path.Combine( Application.persistentDataPath, "file.dat" ), FileMode.Open );
 byte[] byteArray= new byte[ fs.Length ];
 fs.Read( byteArray, 0, Convert.ToInt32( fs.Length ) );
 fs.Close( );

The best overloaded method match for `System.IO.Stream.Write(byte[], int, int)' has some invalid arguments

That's the error I had. I'm using byte like this:

 byte[,,] saveThis;

And the code wants:

  byte[]
