这可能有一个非常简单的答案,已在某处发布,但也有很多关于线程的误导性信息。
我的问题是:在后台工作完成之前,如何阻止我的控制台终止?由于Task
是在我的程序的业务层中创建的,所以当Console终止时我无法访问它(不像在这个简单的例子中)。有没有办法等待在我的应用程序上下文中创建的所有任务?
public class Program
{
private static void Main(string[] args)
{
DoBackgroundWork();
System.Console.WriteLine("Doing something else during background work");
// Wait for all created Tasks to complete before terminating
???
}
private static void DoBackgroundWork()
{
var task = Task.Run(() =>
{
System.Console.WriteLine("Starting background work");
Thread.Sleep(10000);
System.Console.WriteLine("Background work finished!");
});
}
}

返回任务,以便您可以等待它。
private static void Main(string[] args)
{
var task = DoBackgroundWork();
System.Console.WriteLine("Doing something else during background work");
// Wait for all created Tasks to complete before terminating
task.Wait();
}
private static Task DoBackgroundWork()
{
var task = Task.Run(() =>
{
System.Console.WriteLine("Starting background work");
Thread.Sleep(1000);
System.Console.WriteLine("Background work finished!");
});
return task;
}
