The Directory command is used to retrieve an array of all the files in a directory.
- Start a new project called directory.
- Add a listbox named lstFiles.
- Find a folder on your computer with some files that you can use.
- If necessary, create a folder call C:/mydata and copy a few files to it.
- Write the code in form load as shown below, changing the Directory statement to the folder on your computer with the files.
// Programmer: Janet Joy
// Get all of the files in a directory

using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO;
namespace directory
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
// Get an array of all the files in the directory.
string[] files = Directory.GetFiles(@"c:\MyData\");
// Add each file to the combo box.
foreach(String s in files)
{
lstFiles.Items.Add(s);
}
}
}
}
When you run the program you will see a list of all the files in the folder:
