Question

c#线程中使用委托。委托中操作了多个控件，界面卡死

Answer 1

在调用线程之前，打开自定义的进度条控件。之后再线程委托里边操作界面上的多个控件，导致进度条和界面卡死。//打开进度条 progressBar = new ProgressShow("初始化数据请稍候..."); progressBar.Show();//线程System.Threading.Thread treed3 = new System.Threading.Thread(new System.Threading.ThreadStart(mytest)); treed3.Start(); while (treed3.ThreadState == System.Threading.ThreadState.Running){Application.DoEvents(); }//关闭进度条 progressBar.Close();/// private void mytest(){try{ delegate void delInfo(); delInfo MyDelInfo = new delInfo(newThreadInfo); this.Invoke(MyDelInfo);// (new delInfo(newThreadInfo)); } newThreadInfo中操作多个界面控件}catch (Exception ex){progressBar.Close();
