进度条不更新

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("");
                writer.WriteLine("");

                foreach (Resident res in site.GetCustomers())
                {
                    bw.ReportProgress((count / customers) * 100);
                    writer.WriteLine("\t");
                    writer.WriteLine("\t\t" + res.reference + "");
                    writer.WriteLine("\t\t" + res.name + "");
                    writer.WriteLine("\t\t" + res.address + "");
                    writer.WriteLine("\t\t" + res.method + "");
                    writer.WriteLine("\t\t" + res.cycle + "");
                    writer.WriteLine("\t\t" + CheckWebStatus(res.reference) + "");
                    writer.WriteLine("\t");
                    count++;
                }

                writer.WriteLine("");
                writer.Close();
            }
            catch (Exception ex)
            {
                lastException = ex;
            }
        }
    }

它使用相同的BackgroundWorker从数据库中获取数据.我的进度条在从数据库中读取时正确显示进度.但是,在将XML写入的进度条归零后,即使进程正确完成,它也只是位于0.

谁有人建议为什么？

可能是(计数/客户)被截断为零(两个整数之间的划分)？

我认为应该是(数*100)/客户,假设你想要一个百分比完成.
