[英]how to log Unhandled Exception in Silverlight 5
我想捕获并记录Silverlight 5应用程序中发生的未处理异常。 我已经连接了Application.UnhandledException委托。 问题是,在抛出异常之后,我能做什么,不能做什么? 此Silverlight应用程序在托管WebControl(IE的引擎)的C ++应用程序中运行,并且此主机正在实现外部功能。 所以这就是Application.UnhandledException的函数:
private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e)
{
var ex = e.ExceptionObject;
// This is a reference to the
var external = External.Instance;
// loop through all the exceptions and call the hosts 'external' method so the
// host is able to write out the error to a local log file
while (external != null && ex != null)
{
external.LogException(ex.Message, ex.StackTrace);
ex = ex.InnerException;
}
// If the app is running outside of the debugger then report the exception using
// a ChildWindow control.
if (!System.Diagnostics.Debugger.IsAttached)
{
// NOTE: This will allow the application to continue running after an exception has been thrown
// but not handled.
// For production applications this error handling should be replaced with something that will
// report the error to the website and stop the application.
e.Handled = true;
ChildWindow errorWin = new ErrorWindow(e.ExceptionObject);
errorWin.Show();
}
}
目标是记录错误并使应用程序保持运行。
