Manage memory in MonoGame

Content

Hi! On begin, i want greet all :wink: Just now, I sorry for my english - i learn it.
I’m writing to you, because I have problem with manage memory in MonoGame. I’m beginner programmer and I know MonoGame since one week ;P.
Going to the case. I have my project, what I divided on classes. I have one MainClassGame, and other classes, what are scenes. This look like this:
MainClass:

public class MainGame : Game
{
protected override void Initialize()
{
}
protected override void LoadContent()
{
}
protected override void UnloadContent()
{

    }

protected override void Update(GameTime gameTime)
{
if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
Exit();
// TODO: Add your update logic here
if (MenuState.IsShowMainMenuScene)
mainMenuScene.Update();
if (MenuState.IsShowAboutScene)
aboutScene.Update();
if (MenuState.IsShowSettingsScene)
settingsScene.Update();
//
base.Update(gameTime);
}
protected override void Draw(GameTime gameTime)
{
if (MenuState.IsShowMainMenuScene)
mainMenuScene.Draw(spriteBatch, gameTime);
if (MenuState.IsShowAboutScene)
aboutScene.Draw(spriteBatch, gameTime);
if (MenuState.IsShowSettingsScene)
settingsScene.Draw(spriteBatch, gameTime);
if(MenuState.IsShowGameScene)
//
base.Draw(gameTime);
}
}

And in other class, it’s methods Update and Draw.
This is:

public class SettingsScene : DrawableGameComponent
{
Game game;
ContentManager Content;

    public SettingsScene(Game game) : base(game)
    {
        this.game = game;
        LoadContent();
    }

    protected override void LoadContent()
    {
        Content = new ContentManager(game.Services);
        Content.RootDirectory = game.Content.RootDirectory;          
    }

    public void Draw(SpriteBatch spriteBatch, GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);

        spriteBatch.Begin();
        //
        spriteBatch.End();
    }

    public void Update()
    {
        
    }
}

I find solved my problem with destruct unusable classes and unload unusable content:
I write destructor in “other class”:

~MyScene(){
Content.Unload();
}

And call it, in my MainClass:

if (MenuState.IsShowSettingsScene)
{
if(settingsScene !=null)
settingsScene.Update();
else{
settingsScene = new SettingsScene(this);
}
}
else
{
settingsScene = null;
GC.Collect();
}

This solved, called my destructor in “other class” and unload my content, but usable memory is for all time does not change.

My question:

  1. How to do unload my content, when i don’t use my “other class” ?

[EDIT Where are my manners, HI!, also did not realise how much of a bump this would be…]

Are you using unmanaged resources?

If you are you could look at expanding into the Dispose() Method

Looks like if this is File related, it may help…

Hope it helps, if not you learnt a useful C# feature :slight_smile: Win Win situations :slight_smile:
