C# datatable to listview

foreach (DataRow row in data.Rows)
{
    ListViewItem item = new ListViewItem(row[0].ToString());
    for (int i = 1; i < data.Columns.Count; i++)
    {
        item.SubItems.Add(row[i].ToString());
    }
    listView_Services.Items.Add(item);
}

Update: also, if you're calling your method more than once, you need to either clear the columns collection before adding the columns, or check to see if the columns have already been added - otherwise, the number of columns will keep increasing every time you call your method.
