Windows phone 未处理异常的 错误报告页面

1.创建ErrorPage页面，增加如下代码：

        public static Exception Exception;

        // Executes when the user navigates to this page.
        protected override void OnNavigatedTo(NavigationEventArgs e)
        {
            ErrorText.Text = Exception.ToString();
        }

2.修改App页面：

// Code to execute on Unhandled Exceptions
        private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e)
        {
            if (System.Diagnostics.Debugger.IsAttached)
            {
                // An unhandled exception has occurred; break into the debugger
                System.Diagnostics.Debugger.Break();
            }
           e.Handled = true;

            //theException 这是一个静态成员，所以通过类名直接访问。
            ErrorPage.theException = e.ExceptionObject;
            (RootVisual as Microsoft.Phone.Controls.PhoneApplicationFrame).Source = new Uri("/ErrorPage.xaml",UriKind.Relative);
        }
