SmartThreadPool阻止UI线程 [英] SmartThreadPool Blocking UI Thread

问题描述

单击按钮时，我正在运行以下代码:

I am running the following code when i click on a button:

                foreach (string item in urlQueue)
                {

                    log("creating job " + iia.ToString());
                    _smartThreadPool.QueueWorkItem(
                        new Amib.Threading.Func<string, int, int, string, int>(checkURLSmart),
                        item, iia, 5000, kryptonTextBox1.Text);

                    iia++;
                }

                Application.DoEvents();

                _smartThreadPool.Start();

                _smartThreadPool.WaitForIdle();
                _smartThreadPool.Shutdown();

由于某种原因，这阻塞了UI线程，有什么主意如何解决?我希望用户界面在队列工作时能够响应

For some reason this is blocking the UI thread, any ideas how to fix this? I want the UI to be responsive while the queue is working

推荐答案

您不应在GUI线程中调用WaitForIdle(). 使用 http://msdn.microsoft.com/en-us/library/a06c0dc2 .NET或 http:.aspx //p.docs.oracle.com/javase/7/docs/api/javax/swing/SwingUtilities.html Java中的invokeLater().

You shouldn't call WaitForIdle() in GUI thread. Use http://msdn.microsoft.com/en-us/library/a06c0dc2.aspx in .NET or http://docs.oracle.com/javase/7/docs/api/javax/swing/SwingUtilities.html invokeLater() in Java instead.

此机制将您的代码放入队列中，以便在GUI线程中执行.因此，您可以使用回调参数中已处理的数据来更新GUI视图.

This mechanism put your code in queue for execution in GUI thread. So you are able to update GUI view with processed data in callback parameters.
