This will help you it's working.

Microsoft.Office.Interop.Excel.Application oXL;
Microsoft.Office.Interop.Excel.Workbook mWorkBook;
Microsoft.Office.Interop.Excel.Sheets mWorkSheets;
        
oXL = new Microsoft.Office.Interop.Excel.Application();
oXL.Visible = true;
oXL.DisplayAlerts = false;
mWorkBook = oXL.Workbooks.Open(path, 0, false, 5, "", "", false, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "", true, false, 0, true, false, false);
//Get all the sheets in the workbook
mWorkSheets = mWorkBook.Worksheets;
foreach (Microsoft.Office.Interop.Excel.Worksheet pivotSheet in mWorkSheets)
{
    Microsoft.Office.Interop.Excel.PivotTables pivotTables = pivotSheet.PivotTables();
    int pivotTablesCount = pivotTables.Count;
    if (pivotTablesCount > 0)
    {
        for (int i = 1; i <= pivotTablesCount; i++)
        {
            pivotTables.Item(i).RefreshTable(); //The Item method throws an exception
        }
    }
}
