you can use ListBox like this:
private void button1_Click(object sender, System.EventArgs e)
{
// Create an instance of the ListBox.
ListBox listBox1 = new ListBox();
// Set the size and location of the ListBox.
listBox1.Size = new System.Drawing.Size(200, 100);
listBox1.Location = new System.Drawing.Point(10,10);
// Add the ListBox to the form.
this.Controls.Add(listBox1);
// Set the ListBox to display items in multiple columns.
listBox1.MultiColumn = true;
// Set the selection mode to multiple and extended.
listBox1.SelectionMode = SelectionMode.MultiExtended;
// Shutdown the painting of the ListBox as items are added.
listBox1.BeginUpdate();
// Loop through and add 50 items to the ListBox.
for (int x = 1; x <= 50; x++)
{
listBox1.Items.Add("Item " + x.ToString());
}
// Allow the ListBox to repaint and display the new items.
listBox1.EndUpdate();
// Select three items from the ListBox.
listBox1.SetSelected(1, true);
listBox1.SetSelected(3, true);
listBox1.SetSelected(5, true);
// Display the second selected item in the ListBox to the console.
System.Diagnostics.Debug.WriteLine(listBox1.SelectedItems[1].ToString());
// Display the index of the first selected item in the ListBox.
System.Diagnostics.Debug.WriteLine(listBox1.SelectedIndices[0].ToString());
}

Have a look at the ListBox class. This MSDN page has many examples. Take a look at the Items property which holds the list of items.
