Issue with using OpenSlide

I am new to C# and can't get OpenSlide to work. I need it to be able to read SVS files. Below is the code I have used. Is it possible I am missing something in a directory? My boss has used the same code and can get it to run without issue.
I am getting the following error:
OpenSlideNET.OpenSlideUnsupportedFormatException: 'Exception of type 'OpenSlideNET.OpenSlideUnsupportedFormatException' was thrown.'
using OpenSlideNET;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;

{
public partial class Form1 : Form
{

}
private void button1_Click(object sender, EventArgs e)
{
OpenSlideImage image = OpenSlideImage.Open("‪C:\\projects\\SVS\\JP2K-33003-1.svs");
}
}
}

Button doesn't work, no issues are found, did I write something wrong?

private void button1_Click(object sender, EventArgs e)
{
WMPLib.WindowsMediaPlayer wplayer = new WMPLib.WindowsMediaPlayer();
wplayer.URL = #"C:\Users\Cristi\Music\DOOM CROSSING Eternal HorizonsMusic Video feat. Natalia Natchan.mp3";
wplayer.controls.play();
}
}
}
I am trying to make a Winforms program that plays an audio file, there is no error when debugging but when I fire it up and press the button, nothing plays.
I have tried to make another button and use that one but it still doesn't work, any help?

C# ReadallLines display in ListBox Not Working

I am new to C# and have been trying for hours to accomplish this simple task of reading a file into an array and displaying in a listbox. However, it never seems to read the file and the listbox is blank and I don't get any errors. What am I missing?

access selected item from another from

I have two forms: one has a listbox with a list<>. I need to access the selected item of this textbox on a second form.
First form(GestaoJogadores_Admin):
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class GestaoJogadores_Admin : Form
{
private DiagramaEntidadesContainer dbATMT;
public GestaoJogadores_Admin()
{
InitializeComponent();
dbATMT = new DiagramaEntidadesContainer();
RefreshListaJogadores();
}
private void button_editarGestaoJogadores_Click(object sender, EventArgs e)
{
EditarJogador_Admin EditarJogadorAdmin = new EditarJogador_Admin();
Player jogadorSelecionado = (Player)lb_Jogadores.SelectedItem;
DialogResult resultado = EditarJogadorAdmin.ShowDialog();
}
}
}
Second form(EditarJogador_Admin)
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class EditarJogador_Admin: Form
{
private DiagramaEntidadesContainer dbATMT;
public EditarJogador_Admin()
{
InitializeComponent();
dbATMT = new DiagramaEntidadesContainer();
}
private void button_EditarJogadorOk_Click_1(object sender, EventArgs e)
{
GestaoJogadores_Admin GestaoJogadoresAdmin = new GestaoJogadores_Admin();
Player jogadorSelecionado = (Player)GestaoJogadoresAdmin.jogadorSelecionado;//this is what I need, but it doenst work. I get an errror: 'GestaoJogadores_Admin' does not contain a definition for 'jogadorSelecionado' and no extension method 'jogadorSelecionado' accepting a first argument of type 'GestaoJogadores_Admin' could be found (are you missing a using directive or an assembly reference?)`
}
}
}
I open my second form creating an instance of it on the first one and using ShowDialog. On the second on, I thought that if I did the same and tried to access the "jogadorSelecionado" inside of it, It would work, but It doesnt...

In your first form on the button change
Player jogadorSelecionado = (Player)lb_Jogadores.SelectedItem;
try
EditarJogadorAdmin.passFromFormOne = (Player)lb_Jogadores.SelectedItem;
And on your second form add the variable to pass it too.
public Player passFromFormOne;
then
Player jogadorSelecionado = passFromFormOne;
