ApplicationUnhandledExceptionEventArgs.ExceptionObject Property


Gets or sets the unhandled exception.

Namespace:  System.Windows
Assembly:  System.Windows (in System.Windows.dll)

public Exception ExceptionObject { get; set; }

Property Value

Type: System.Exception
The unhandled exception.

This property is read-write in the object model, but your application code would not typically write to it. The property is intended to report the conditions of an error that is raised by Silverlight.

The following example shows how to handle and use the UnhandledException event.

using System.IO; // FileNotFoundException
using System.Windows; // Application, StartupEventArgs, ApplicationUnhandledExceptionEventArgs

namespace SilverlightApplication
    public partial class App : Application
        public App()
            this.Startup += this.Application_Startup;
            this.UnhandledException += this.Application_UnhandledException;


        private void Application_Startup(object sender, StartupEventArgs e)
            this.RootVisual = new Page();

        private void Application_UnhandledException(object sender, 
            ApplicationUnhandledExceptionEventArgs e)
            if (e.ExceptionObject is FileNotFoundException)
                // Inform the user

                // Recover from the error
                e.Handled = true;

            // Exception is unrecoverable so stop the application and allow the 
            // Silverlight plug-in control to detect and process the exception.
