網上找的C# WinForm全域性異常捕獲方法,程式碼如下:
static class Program { /// <summary> /// 應用程式的主入口點。 /// </summary> [STAThread] static void Main() { try { //設定應用程式處理異常方式:ThreadException處理 Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException); //處理UI執行緒異常 Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException); //處理非UI執行緒異常 AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); #region 應用程式的主入口點 Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); #endregion } catch (Exception ex) { string str = GetExceptionMsg(ex,string.Empty); MessageBox.Show(str, "系統錯誤", MessageBoxButtons.OK, MessageBoxIcon.Error); } } static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e) { string str = GetExceptionMsg(e.Exception, e.ToString()); MessageBox.Show(str, "系統錯誤", MessageBoxButtons.OK, MessageBoxIcon.Error); //LogManager.WriteLog(str); } static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { string str = GetExceptionMsg(e.ExceptionObject as Exception, e.ToString()); MessageBox.Show(str, "系統錯誤", MessageBoxButtons.OK, MessageBoxIcon.Error); //LogManager.WriteLog(str); } /// <summary> /// 生成自定義異常訊息 /// </summary> /// <param name="ex">異常物件</param> /// <param name="backStr">備用異常訊息:當ex為null時有效</param> /// <returns>異常字串文字</returns> static string GetExceptionMsg(Exception ex,string backStr) { StringBuilder sb = new StringBuilder(); sb.AppendLine("****************************異常文字****************************"); sb.AppendLine("【出現時間】:" + DateTime.Now.ToString()); if (ex != null) { sb.AppendLine("【異常型別】:" + ex.GetType().Name); sb.AppendLine("【異常資訊】:" + ex.Message); sb.AppendLine("【堆疊呼叫】:" + ex.StackTrace); } else { sb.AppendLine("【未處理異常】:" + backStr); } sb.AppendLine("***************************************************************"); return sb.ToString(); } }
