Question

在一个窗体中点一个按钮执行另一个类中的方法
public void PublishAllHouse(List<int> WebId, List<int> HouseId)
        {
            int AllCount = 0;
            try
            {
                //new Thread(() =>
                //{
                //    Control.BeginInvoke(new Action(() =>  
                //    {
                        Thread.Sleep(200);
                        for (int i = 0; i <= HouseId.Count - 1; i++)
                        {
                            for (int j = 0; j <= WebId.Count - 1; j++)
                            {
                                PublishHouseFactory publishhousefactory = new PublishHouseFactory();
                                PublishHouse publishhouse = null;
                                publishhouse = publishhousefactory.CreatePublishHouse(WebId[j].ToString());
                                PublishHouse.WebInfoId = WebId[j];
                                PublishHouse.HouseInfoId = HouseId[i];
                                AllCount++;
                                Thread t = new Thread(new ThreadStart(publishhouse.ToPublishHouse));
                                t.Start();
                                //Thread.Sleep(500);
                                //Control.Invoke((MethodInvoker)delegate
                                //{
                                //    publishhouse.ToPublishHouse();
                                //});
                            }
                        }
                //    }));
                //}).Start();
            }执行这个方法时窗体不能拖动了，怎么解决，谢谢！！

Answer 1

publishhouse.ToPublishHouse
这里是不是以开始就要和ui同步，执行Invoke吧所有操作都括进去了？
线程的目的是尽量释放ui线程占用。
你检查一下，在必要时候，使用
this.Invoke((EventHandler)delegate
{
//更新ui
});
非ui的消耗时间的不要Invoke中写。
Invoke就把线程和ui线程同步到一起了。

Answer 2

在for循环里面开启线程不是一个好的做法，再梳理一下程序逻辑流程，尽量不要这么干

Answer 3

PublishAllHouse这个方法的执行不要使用同步，异步解决

Answer 4

你的意思线程中创建了窗体？如何创建的？
哪个窗体要想拖动也是以来消息，你要么一段时间执行Application.DoEvents();要么再开一个线程执行Application.Run(窗体);来单独处理窗体消息。

Answer 5

开一个线程,我想你自己原来有思路的,但不知道为什么要改成在循环里不停开线程.
                new Thread(() =>
                {
                    for (int i = 0; i <= HouseId.Count - 1; i++)
                    {
                        for (int j = 0; j <= WebId.Count - 1; j++)
                        {
                            PublishHouseFactory publishhousefactory = new PublishHouseFactory();
                            PublishHouse publishhouse = null;
                            publishhouse = publishhousefactory.CreatePublishHouse(WebId[j].ToString());
                            PublishHouse.WebInfoId = WebId[j];
                            PublishHouse.HouseInfoId = HouseId[i];
                            AllCount++;
                            publishhouse.ToPublishHouse();
                        }
                    }                }).Start();
