我们在C＃中开发了Window服务，在后台worker的帮助下使用TcpClient读取数据。在这里，我们正在从多个IP中读取数据，因此使用后台工作程序数组来实现此目的。我们的服务工作得非常好，但几个小时后，其中一个线程停止运行。对于这里，我正在粘贴与此问题相关的功能。 调用序列 1. StartMonitoring 2. Dowork
假设有两行来自数据库，因此创建了两个后台工作者对象，这些对象将调用backgroundWorkerFiles_DoWork函数。 在backgroundWorkerFiles_DoWork函数中，int i =（int）e .Argument;首先是0然后是1，根据0和1，它们将IP连接到其端口。但是经过一段时间我总是来1而不是0.最初两次运行但是一个线程停止运行并且总是给1连接IP而不是0。 请帮助我们摆脱这个问题。我也在努力。如果你愿意，我也可以粘贴完整的代码。

我已将后台工作者转换为TASK库。现在问题解决了谢谢。改变了以下内容： -
public static Task [] BackgroundWorker_Controllers = new Task [maxThreads]; // declration
//调用
for (int f = 0; f < maxThreads; f++)
{
var ii = f;
BackgroundWorker_Controllers[f] = new Task(() =>
{
ConnectControllers(ii, dt.Rows.Count); }, TaskCreationOptions.None);
BackgroundWorker_Controllers[f].Start();
}
