c# – 如何等待BackgroundWorker完成,然後退出控制檯應用程式

我已經編寫了一個示例控制檯應用程式,以使用Stackoverflow中釋出的示例之一來測試backgroundworker.我有一個背景工作者,從主要方法開始,但是如果我按enter鍵,結束於操作的中間,因為我在main方法中編寫了一個console.readkey.但是我希望它等到後臺工作人員完成這項工作,然後退出應用程式.這是我的程式碼

class Program
{
private static BackgroundWorker worker = new BackgroundWorker();
private event EventHandler BackgroundWorkFinished;

static void Main(string[] args)
{
worker.DoWork += worker_DoWork;
worker.RunWorkerCompleted += worker_RunWorkerCompleted;
worker.ProgressChanged += worker_ProgressChanged;
worker.WorkerReportsProgress = true;
worker.WorkerSupportsCancellation = true;

Console.WriteLine("Starting Application...");

worker.RunWorkerAsync();
Console.ReadKey();
}

static void worker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
Console.WriteLine(e.ProgressPercentage.ToString());
}

static void worker_DoWork(object sender, DoWorkEventArgs e)
{
Console.WriteLine("Starting to do some work now...");
int i;
for (i = 1; i < 10; i++)
{
Thread.Sleep(1000);
worker.ReportProgress(Convert.ToInt32((100.0 * i) / 10));
}

e.Result = i;
}

static void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
Console.WriteLine("Value Of i = " + e.Result.ToString());
Console.WriteLine("Done now...");
}
}

請參閱ofollow,noindex" target="_blank">How to wait for a BackgroundWorker to cancel?

的帖子,瞭解如何在您的BackgroundWorker和主執行緒之間進行通訊.

基本上,您必須使用您在DoWork結束時設定的事件來表明DoWork已完成.然後在主執行緒中的那個事件上WaitOne().
