問題描述
從概念上講，我想完成以下操作，但在理解如何在 C# 中正確編碼時遇到了麻煩:
Conceptually, I would like to accomplish the following but have had trouble understand how to code it properly in C#:
SomeMethod { // Member of AClass{}
DoSomething;
Start WorkerMethod() from BClass in another thread;
DoSomethingElse;
}
然后，當 WorkerMethod() 完成時，運行:
Then, when WorkerMethod() is complete, run this:
void SomeOtherMethod() // Also member of AClass{}
{ ... }
誰能舉個例子?
推薦答案
BackgroundWorker 類正是為此目的添加到 .NET 2.0 中的.
The BackgroundWorker class was added to .NET 2.0 for this exact purpose.
簡而言之:
BackgroundWorker worker = new BackgroundWorker();
worker.DoWork += delegate { myBClass.DoHardWork(); }
worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(SomeOtherMethod);
worker.RunWorkerAsync();
如果需要，您還可以添加諸如取消和進度報告之類的奇特內容:)
You can also add fancy stuff like cancellation and progress reporting if you want :)
