c# - 进度条不更新

Question

我有以下代码将数据写入 XML 文件。

private void WriteResidentData()
{
    int count = 1;
    status = "Writing XML files";
    foreach (Site site in sites)
    {
            try
            {
                //Create the XML file
                StreamWriter writer = new StreamWriter(path + "\\sites\\" + site.title + ".xml");
                writer.WriteLine("<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ?>");
                writer.WriteLine("<customer_list>");

                foreach (Resident res in site.GetCustomers())
                {
                    bw.ReportProgress((count / customers) * 100);
                    writer.WriteLine("\t<customer>");
                    writer.WriteLine("\t\t<customer_reference>" + res.reference + "</customer_reference>");
                    writer.WriteLine("\t\t<customer_name>" + res.name + "</customer_name>");
                    writer.WriteLine("\t\t<customer_address>" + res.address + "</customer_address>");
                    writer.WriteLine("\t\t<payment_method>" + res.method + "</payment_method>");
                    writer.WriteLine("\t\t<payment_cycle>" + res.cycle + "</payment_cycle>");
                    writer.WriteLine("\t\t<registered>" + CheckWebStatus(res.reference) + "</registered>");
                    writer.WriteLine("\t</customer>");
                    count++;
                }

                writer.WriteLine("</customer_list>");
                writer.Close();
            }
            catch (Exception ex)
            {
                lastException = ex;
            }
        }
    }

它使用从数据库获取数据的同一个 BackgroundWorker。我的进度条在从数据库读取时正确显示进度。然而，在将 XML 写入的进度条归零后，即使该过程正确完成，它也只是停留在 0。

谁能告诉我为什么？

会不会是 (count/customers) 被截断为零(两个整数之间的除法)？
