'How do I call the injected dependency 'level' and use it as a condition in an IF statement? C#

An object reference is required for the non-static field, method, or property 'Form1.level'

public Form1( int level ) {
    this.level = level;
    playtune();
    InitializeComponent();
}
// the value is actually 1 and the 0 is just to declare the variable
int level = 0;

static void playtune()
{
    SoundPlayer tune = new SoundPlayer(
        GameProject.Properties.Resources.level_audio_mario);
    if (level == 2)
    {
        tune = new SoundPlayer(GameProject.Properties.Resources.level_audio_sonic);
    }
    tune.Play();
}

Can you change your method to non static?

static void playtune()

=>

    void playtune()
    {
        SoundPlayer tune = new SoundPlayer(GameProject.Properties.Resources.level_audio_mario);
        if (this.level == 2)
        {
            tune = new SoundPlayer(GameProject.Properties.Resources.level_audio_sonic);
        }
        tune.Play();
    }
