c#winform将全局异常抛出,不用大量写try()catch()
一、在program.cs处完善成如下,但是这样后只能抛出主线程(UI)的错误,所以请看第二步
/// 应用程序的主入口点。 /// </summary> [STAThread] static void Main() { //全局异常捕捉 Application.ThreadException += Application_ThreadException; //UI线程异常 AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException; //多线程异常 Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new FrmMain()); } //UI线程异常 static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e) { WinformException.FrmBugReport.ShowBug(e.Exception); } //多线程异常 static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { WinformException.FrmBugReport.ShowBug((Exception)e.ExceptionObject); }
二、将其他线程异常抛掷到主线程
// Thread t = new Thread((ThreadStart)delegate { try { throw new Exception("非窗体线程异常"); } catch (Exception ex) { this.BeginInvoke((Action)delegate { throw ex; }); } }); t.Start();
