Application.Exit Event

Silverlight

Other Versions

Occurs just before an application shuts down and cannot be canceled.

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

Syntax

Copy

public event EventHandler Exit

XAML Attribute Usage

Copy

<Application Exit="eventhandler"/>

Remarks

You can detect when an application shuts down by handling the Exit event. This allows your application to perform common application shutdown tasks, including saving data for the next application session and logging.

Important Note:
An Exit event handler should not include long-running, re-entrant, or cyclic code, such as resetting the Silverlight plug-in's Source property.

Examples

The following code shows how to handle Exit using markup and code-behind.

XAML

Copy


<Application 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    x:Class="SilverlightApplication.App"
    Startup="App_Startup"
    Exit="App_Exit">

</Application>

Copy


using System; // EventArgs
using System.Windows; // Application

namespace SilverlightApplication
{
    public partial class App : Application
    {
        public App()
        {
            InitializeComponent();
        }

        private void App_Startup(object sender, StartupEventArgs e)
        {
            // The application has started.
        }

        private void App_Exit(object sender, EventArgs e)
        {
            // The application is about to stop running.
        }
    }
}
