SoundEffect and trouble

Question

I have a problem with SoundEffect

Button1

            var stream = TitleContainer.OpenStream("Music/music1.wav");
            var music1 = SoundEffect.FromStream(stream);
            FrameworkDispatcher.Update();
           
            music1.Play();

Button2 does not work (Error)

music1.Stop();

Answer 1

What error do you get?

Answer 2

The name 'music1' does not exist in the current context

Answer 3

music1 is a local variable defined in the Button1 click method. You may want to define that variable outside of the method to ensure that both methods can access it.

var music1;

void Button1_Click(object sender, EventArgs args)
{
    music1.Play();
}

void Button2_Click(object sender, EventArgs args)
{
    music1.Stop();
}

 

Answer 4

Again there is an error

            var stream = TitleContainer.OpenStream("Music/music1.wav");
            var music1 = SoundEffect.FromStream(stream);
            FrameworkDispatcher.Update();


void Button1_Click(object sender, EventArgs args)
{
    music1.Play();
}

void Button2_Click(object sender, EventArgs args)
{
    music1.Stop();
}

Error

Invalid token '(' in class, struct, or interface member declaration

Answer 5

var music1;

 
void Button1_Click(object sender, EventArgs args) 
{ 
    var stream = TitleContainer.OpenStream("Music/music1.wav"); 
    music1 = SoundEffect.FromStream(stream); 
    FrameworkDispatcher.Update(); 

    music1.Play(); 
} 
 
void Button2_Click(object sender, EventArgs args) 
{ 
    if (music1 != null)
        music1.Stop(); 
}

Answer 6

This is strange! 

Copy > Paste and I got error...

The contextual keyword 'var' may only appear within a local variable declaration
