You need to look into the Office Interop Libraries, see this example take from here.

Microsoft.Office.Interop.Excel.Application xl = 
    new Microsoft.Office.Interop.Excel.Application();

xla.Visible = true;
Workbook wb = xla.Workbooks.Add(XlSheetType.xlWorksheet);
Worksheet ws = (Worksheet)xla.ActiveSheet;
int i = 1;
int j = 1;
foreach (ListViewItem comp in lvwResults.Items)
{
    ws.Cells[i, j] = comp.Text.ToString();
    //MessageBox.Show(comp.Text.ToString());
    foreach (ListViewItem.ListViewSubItem drv in comp.SubItems)
    {
        ws.Cells[i, j] = drv.Text.ToString();
        j++;
    }
    j = ;1;
    i++;
}

This of course requrires that you have Excel installed on the machine running the program.
