我有一个小的C#应用程序,它使用POST方法通过API请求与服务器通信并获取一些数据。顺便说一下,它是一个Apache服务器。
我的问题是我的C#应用程序不断发送大量请求,服务器会创建大量日志文件。
我使用BackgroundWorker,我想暂停几秒钟,但Thread.Sleep(5000)无效。
此应用程序在系统托盘中运行,它没有GUI,只是获取一些内容,然后打印出来。
代码:
private void _bgWorker_DoWork(object sender, DoWorkEventArgs e)
{
JSONParser parser = new JSONParser(_config.Prop.server + "content/api.php", "print", "getAll");
try
{
while (!_bgWorker.CancellationPending)
{
try
{
JSONPrintNeeds needs = parser.DownloadAll();
List<JSONPrintNeed> temp = new List<JSONPrintNeed>();
foreach (JSONPrintNeed need in needs.data)
{
temp.Add(need);
}
foreach (JSONPrintNeed need in temp)
{
Printer printer = new Printer(need.megrendeles);
printer.PrintController = new StandardPrintController();
List<String> installed = new List<String>();
for (int i = 0; i < PrinterSettings.InstalledPrinters.Count; i++)
{
installed.Add(PrinterSettings.InstalledPrinters[i]);
}
if (installed.Contains(need.nyomtato))
{
printer.PrinterSettings.PrinterName = need.nyomtato;
}
int format = int.Parse(need.format);
switch (format)
{
case 0:
default: // txt
printer.Print();
break;
case 1: // html
SetDefaultPrinter(need.nyomtato);
browser.DocumentText = need.megrendeles;
browser.Print();
break;
}
JSONResult result = parser.DeleteOne(int.Parse(need.ny_id));
}
parser.DeleteAll();
Thread.Sleep(5000);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}

您可以将EventWaitHandle
用于同步主题。
EventWaitHandle flag = new EventWaitHandle(false, EventResetMode.AutoReset);
if (stop)
{
flag.WaitOne(5000);
}
