this.notifyIcon.Icon = System.Drawing.Icon.ExtractAssociatedIcon(System.Windows.Forms.Application.ExecutablePath);
线程池
ThreadPool.QueueUserWorkItem(callBack =>
{
XiaoAoHelper.logout();
});
解决办法:
1.
直接在窗体的构造函数中加:System.Windows.Forms.Control.CheckForIllegalCrossThreadCalls = false;此时把所有的控件合法性线程检查全部都给禁止掉了。
Thread t2 = new Thread(() => { for (int i = 1; i <= 10; i++) { this.BeginInvoke(new Action(() => { progressBar1.Value = i * 10; })); Thread.Sleep(1000); } }); t2.IsBackground = true; t2.Start();
private void CheckUpdateVersionAnsyn() { try { Uri endpoint = new Uri(string.Format("{0}v.aspx?timer={1}", App.Url, DateTime.Now.ToString())); WebClient client = new WebClient(); var are = new AutoResetEvent(false); client.DownloadStringCompleted += (s, e) => { are.Set(); if (e.Error == null) { int ver = 0; ver = ExecVaspx(e.Result); base.Dispatcher.BeginInvoke(() => { if (Application.Current.IsRunningOutOfBrowser) { OOBUpApp(ver); } else { reLogin(); } }); } else { base.Dispatcher.BeginInvoke(() => { reLogin(); App.ShowMessage("网络连接失败,未获取到新版本!", AletrEnum.Error); }); } }; client.DownloadStringAsync(endpoint); if (!are.WaitOne(5000)) { base.Dispatcher.BeginInvoke(() => { reLogin(); App.ShowMessage("网络连接失败,未获取到新版本!", AletrEnum.Error); }); client.CancelAsync(); } } catch { base.Dispatcher.BeginInvoke(() => { reLogin(); App.ShowMessage("发生系统性错误,无法更新!", AletrEnum.Error); }); } }
