Cant use a Variable for both fields(Text and Selecteditem) : Wanted to use Disk.Diskvolume as a Global Variable so it contains the things from Listbox1, when making the same Variable as a text for a label It throws an error that says: "Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)"	


I made a static class called Disk and included Diskvolume as a static object, I made it so it uses an item from a listbox1 whenever its index has changed, but it seems that it doesnt work for Label.text and when using a string it doesnt work with Listbox1.selectedItem

```
public partial class Form1 : Form
    {
        public static class Disk
        {
         public static string Diskvolume;
        }
        public Form1()
        {
            InitializeComponent();
        }
        private void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            //The Labels Will Change depending on the Chosen DriveLetter
            Disk.Diskvolume = ListBox1.SelectedItem;
            Label2.Text = Disk.Diskvolume;
        }

        private void Button2_Click(object sender, EventArgs e)
        {

        }
    }
```

I expected Disk.Diskvolume to work on both Listbox1.selecteditem and Label2.text.

My problems are particularly in Line 15 and 16 and it has to do with the the Public static.
