listView1.Columns.Add(\"Value\");

I've refined this using an extension method on the ListViewItemsCollection. In my opinion it makes the calling code more concise and also promotes more general reuse.

internal static class ListViewItemCollectionExtender
{
    internal static void AddWithTextAndSubItems(
                                   this ListView.ListViewItemCollection col, 
                                   string text, params string[] subItems)
    {
        var item = new ListViewItem(text);
        foreach (var subItem in subItems)
        {
            item.SubItems.Add(subItem);
        }
        col.Add(item);
    }
}

Calling the AddWithTextAndSubItems looks like this:

// can have many sub items as it's string array
myListViewControl.Items.AddWithTextAndSubItems("Text", "Sub Item 1", "Sub Item 2"); 

Hope this helps!
