Passing combobox selection as a variable?

I am trying to create a very simple form that copies the contents of one directory to a USB flash drive. I have a single combo box populated with available drive letters, and a button to execute.

What I want to do (and where I am getting stuck) is to use xcopy to copy files from one static location (a networked directory) to the drive selected in the combo box.

I know this is probably pretty remedial, but hoping someone can help.

I have been trying to pass it as a variable, but am having all sorts of trouble (which is probably because I don't really know what I am doing yet.

Any suggestions for a wannabe self-taught dev?

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        cmbDrives.DataSource = Environment.GetLogicalDrives();

        int num = 1;
        long bigNum = num;
        1 = cmbDrives.SelectedValue;

What you're looking for is the System.Diagnostics.Process class. And you'll want to put this in the button click handler:

protected void btnGo_Click(object sender, EventArgs e)
{
    string destinationDrive = cmbDrives.SelectedValue.ToString();

    Process.Start("xcopy", string.Format("/someswitch {0} otherarguments", destinationDrive));
}

All that's left is to wire up the event handler. You can do this in the designer or in the Form1() constructor:

btnGo.Click += btnGo_Click;

I think you want to show Combobox item which has "1" value on load event. If it is the case,

cmbDrives.SelectedValue="1";

from your comments : if you want to set the second item(index 1) as the selected item

Replace This:

1 = cmbDrives.SelectedValue;

With this:

cmbDrives.SelectedIndex = 1;

Note : Index is zero based , so you need to assign 0 to select the first Item
