c# - 多个背景工+ C#

快速提问-是否可以让两个后台 worker 同时运行？我似乎记得曾经尝试过一次并遇到错误，并且似乎还记得读到您只能拥有一个……我找不到另一个讨论明确拥有多个的线程。

任何想法都非常感谢!

最佳答案

您可以根据需要拥有任意数量的后台 worker ，这些 worker 可以同时运行。例子:

var worker1 = new BackgroundWorker { WorkerReportsProgress = true };
var worker2 = new BackgroundWorker { WorkerReportsProgress = true };
DoWorkEventHandler doWork = (sender, e) =>
{
    for (int i = 0; i < 10; i++)
    {
        var progress = (int)((i + 1) * 100.0 / 10);
        var worker = (BackgroundWorker)sender;
        worker.ReportProgress(progress);
        Thread.Sleep(500);
    }
};
worker1.DoWork += doWork;
worker2.DoWork += doWork;
worker1.ProgressChanged += (sender, e) =>
{
    label1.Text = e.ProgressPercentage.ToString();
};
worker2.ProgressChanged += (sender, e) =>
{
    label2.Text = e.ProgressPercentage.ToString();
};

worker1.RunWorkerAsync();
Thread.Sleep(1000);
worker2.RunWorkerAsync();
